Unexplained Leap In CO2 Levels
Cally writes "The Guardian is reporting that atmospheric CO2 concentrations have leapt by 4.5 ppm in the last two years. This raises the ugly possibility that the capacity of a large carbon sink (possibly the oceans) has been exceeded, and the worst-case scenario is that a tipping point has been reached and a runaway warming scenario is in progress. Quote from Dr. Piers Foster of Reading University: 'If this is a rate change, of course it will be very significant. It will be of enormous concern, because it will imply that all our global warming predictions for the next hundred years or so will have to be redone.'"
Buildup of atmospheric C02 is moderated by "sinks" on the earth's surface that use some C02 and store much of the carbon in living organisms, organic matter and carbonate minerals, says soil scientist H.H. Cheng. These carbon sinks include the oceans that cover more than 70 percent of the earth surface, forests and other vegetation covering the land, and organic matter in the soil.
Interestingly, this article talks about soil as a possible source of CO2 buildup in the atmosphere, making the El Nino effect not always a good indicator of how much a rise or fall in atmospheric CO2 should be. Finally, here is article that that argues that rises in atmospheric CO2 are not a cause for alarm: PortlandTribune.com | Rise in CO2 levels is no cause for alarm

Disclaimer: I work for a company, but I don't speak for them.
I think this is the first level headed article on the subject I've come across in a while. By looking at the globe in a widespread fashion they've seen logical causes to CO2 rise.
The article does wrap up with "Based on those two years alone I would say it was too soon to say that a new trend has been established, but it warrants close scrutiny."
I've come to belive in a closed carbon cycle, but the easy "pump and use" nature of fossil fuels make biofuels a hard prospect.
Bacardi + slashdot = negative karma.
Every time there is some big post about a comet hitting earth in the next 20 years, or global warming, or any other earth ending disaster it stays in the news for about 1 day. Just long enough for every other scientist in the world to say the guy that came up with it is a crank and the whole thing doesn't matter. I give this one maybe 2 days.
David J Hofmann of the US National Oceanic and Atmospheric Administration centre, which also studies CO2, was more cautious.
"I don't think an increase of 2 ppm for two years in a row is highly significant - there are climatic perturbations that can make this occur," he said. "But the absence of a known climatic event does make these years unusual.
"Based on those two years alone I would say it was too soon to say that a new trend has been established, but it warrants close scrutiny."

Nothing to see here, run along.
I think this 'runaway' global warming effect isn't run away at all. If 30,000 died in last summer's heatwave, why can't we assume that earth is just getting rid of 'excess' baggage? I think earth has a few tricks up its sleeve, and everytime we push her to her limits, she'll fart back and wipe a few of us off until we reach the correct mass again.
Don't worry: your brain will eventually work inspite of you.
Someone will be along soon to tell us that this is all part of a natural progression and we have nothing to worry about and to all go back to driving 5.0 SUVs as we can't hope to understand the climate and so figures are irrelevant and its not are fault etc etc etc. I wonder how many of these people STILL have their heads in the sand after this?
Most of the people here look like they drive 5.0 SUVs, but I doubt they do. Not accepting treehugger mentality does not mean we work for oil companies.

Peat Bogs outburn Western Europe New Scientist 18 Oct 1997
PEAT bogs in Indonesia that have been set alight by the country's raging forest fires could release more carbon dioxide into the atmosphere over the next six months than all the power stations and car engines of Western Europe emit in a year. The finding backs up claims that the fires could have a significant impact on global warming.
Sometimes there is very little that we can do to stop the production of CO2 into our atmosphere. Natural causes, like breathing put tonnes of CO2 into the air. Why haven't we begun a program using iron oxide spread on the ocean to trap and remove CO2? It's viability was proved years ago?. Why are environmentalist opposed to a scientific solution?
"Science is about ego as much as it is about discovery and truth " - I said it, so sue me.
How much more evidence do we need before we start to do something about this problem? The problem, IMHO, is that even if we are at the point of seeing the start of run away global warming there is little incentive for our governments to do anything about it as it won't affect the current generation significantly.
If any of the governments of the world were thinking ahead though they would start investing very heavily in alternative power generation technology. In global terms it's not all that long before we run out of fossil fuels or damage the climate to the point where fossil fuels cost more than they are worth. The country that owns the technology to generate clean power will be in a very strong position. Imagine if your country didn't have to rely on the middle east for transport - suddenly your country becomes very powerful.
At the end of the day though while the American sheeple continue to vote idiots into power nothing is going to be done about the problem.

In math terms:
Barrels of oil TIMES Number of Humans = CO2 production.
Now....how many humans wish to reduce the number of the barrels of oil they use? How many "leaders" will see it eaiser to reduce the number of humans?
FireFox sucks
All the coal and oil on the planet (about 3 teratons) is only about 8% of the carbon dissolved in the oceans. Which seems to imply two things: (1) We need to stir up the oceans a bit to get some of that CO2-poor deep water to the surface. (2) If we got desperate we could mine the waters for carbon.
I tried that about 5 times but farted each time.
Sorry, but I let out more CO2 and Methane than I kept in by holding my breath.
Maybe a buttplug would help?
Leave our cars alone ! Even though they suck in air, burn it with millions years old Dinosaur-meat, then plunge out recycled Dinosaur-meat in the form of CO(2), that doesn't mean they are the problem.
I think we can only test your far fetched hypothesis by producing new 10-20 liter cars, and decrease the petrol cost by 75% at least. If, after say 25 years, we are imitating the faith of the creatures we now burn, I would say we need to discuss the consequences.
In the mean time, keep burning that oil folks !
Slashdot: stuff for news, nerds that matter, matter for news, stuff that nerd
Of course the scientists know the assumptions that their models are based on. They understand those assumptions more than anyone. Models are not just used so scientists can say "hey aren't we smart" they're also used to test the theories they're based on and if the data doesn't match the model then back to the drawing board they go. The fact that models are simplified is down to both theoretical non-understanding and computational and mathematical power (not only are they hard to model some of those equations are just plain hard to solve precisely).

There are so many compounded issues in regards to these figures. The results are very likely to be accurate. The issues that cause increases like this are always no single reason. We are still logging vast amounts of forrest even in the developed world. Its not just something that occurs in the "developing world" like people like to imagine/dream up. Compounding the massive reduction in trees (amazon, daintree etc etc being logged) with the huge and seaddy population increase, and higher than ever demand on power/services because of the increased population... coupling just these factors together makes a massive difference.
End results a warmer world, greater variety of weather patterns and a more F-ed up place to live in for most of the developing world. Most of the "first world" countries will be able to spend the money to shield our poor white arses from the additional heat.. thanks to air con.. but then the issues will be compounded further with the further increase in energy needs..
The end result is people dont want to make the sacrifices on a broad enough level to make a big enough difference fast enough to make a difference in the long term. Coupling Co2 levels with so2 levels increasing as well.. we are in for a real roller coaster ride..

This got scored as a Troll, but the author does have a point. The Earth is probably going to kill us before we kill the Earth - if that is even possible. I am in full agreement that we need to be good stewards of the Earth - but we sometimes go WAY too far down the environmentalist path.

Is anyone familiar with the Kyoto protocol?
m l
It's a United Nations framework of action based on solid scientific research. As others have noticed, the global warming science may be flawed but it's the only one we got. There is NO other real side other than the corporate stock.
for the history the USA's reason for denying it is that "jobs would be lost". spoken again by Bush on the second debate. he also said he'd use alternative versions for the kyoto protocol. Implying bush himself approves its legitimacy.
The full text of the Kyoto Protocol is here.
http://unfccc.int/resource/docs/convkp/kpeng.ht
For a kids' or easy version of the story take a look at the extra dvd of 'the day after tomorrow' movie. a great accounting on environmental issues and kyoto specifically.
He's making a point with logic instead of reacting emotionally. That is quite alot more scientific than much of the knee jerk environmentalism I've seen here so far, IMHO.
Supposing that Earth was operating in a Gaia-ish fashion and needed to "lighten the load", 30000 human death just wouldn't cut it. The human population of Earth is 4.5 billion. Assuming an earth-average pop growth rate of 0.25% (I *know* that pop growth is *negative* in US, China, Japan, Britian, and parts of Africa, but Earth average is positive still) that means 11,250,000 new people on the planet every year (at a minimum). For just summer that would be 2,812,500, and *that* is just to break even. For a healthy die back for the planet, it has to exceed that value. 30,000 doesn't even begin to cut it. Earth needs a major (NON nuclear) war to break out between two large populations, inflicting heavy civilian casulaties. Hmmm... better not give it any ideas...
Given how it's more and more apparent that the cross between geopolitics and global economics are mostly producing a lot of procrastination in facing the pollution music, it's likely we'll at one point have an "carbon-caused temperature emergency", and all carbon-producing things will have be turned off, by law, or some other no-foresight way of trying to deal with the problem at the last minute, whether or not it works.

The answer is simple, its called the precautionary principle. If you don't know what it will do then you better not mess it up in the first place. Too late!
Nah! You better stop farting first.
At best this news is a cause for increased concern and attention. The idea that because we don't fully understand the situation we should do nothing and simply ignore it is absurd.
There is very strong evidence that since the industrial revolution we have significantly increased CO2 input into the ecosystem while at the same time reducing the capacity for CO2 to be locked away as carbon in the world's forests. Now whether or not this has yet had an effect on global temperatures, or will, is still a question to be discussed, although I personally think it almost certainly has.
Someone told me once that if the size of the average car in America were the same as the size of the average car in Europe, America would remove it's entire requirement for Saudi Arabian oil. Does anyone know if that's true?
The earth's carbon sinks are not static in capacity. Everything is interlocked feedback cycles. As CO2 goes up, so too does the growth rate of all vegetation.

It is the naive simplicity of the mathematics used by many lay-men(and sometimes experts) in their discussions of climate change that cause me to seriously doubt their prediction.
Check out this web page for example
http://www.hydrogen.co.uk/h2_now/journal
which tries to use *addition* to predict changes in CO2. We produce X billion tons, the amazon absorbs Y billion tons, net change is X-Y billion tons.
This approach is as hopelessly naive as trying to calculate the flight dynamics of the space shuttle with natural numbers.
That's just not how it works in a real dynamic system and alarmist crap like this only serves to push through ridiculous laws like Kyoto, the funding for which could bring food and water to a huge proportion of the third world instead of affecting some laughable 7% of the annual *human* CO2 output.
Get those people fed and industrialized, and they'll stop cutting down their own forests, start going to school, and add their share of brainpower to the world's thinktank.
SLASHDOT: news for people who can't concentrate on work or have no life at all and got tired of yelling back at the TV.
Measurements of CO2 in the atmosphere have been continuous for almost 50 years at Mauna Loa Observatory, 12,000ft up a mountain in Hawaii, regarded as far enough away from any carbon dioxide source to be a reliable measuring point.
About Mauna Loa:
Rising gradually to more than 4 km above sea level, Mauna Loa is the largest volcano on our planet. Mauna Loa is among Earth's most active volcanoes, having erupted 33 times since its first well-documented historical eruption in 1843.
Through September, more than 580 earthquakes were centered beneath Mauna Loa's summit caldera and the adjacent part of the southwest rift zone. Such a concentrated number of deep LP earthquakes from this part of Mauna Loa is unprecedented, at least in our modern earthquake record dating back to the 1960s.
Spot the coincidence.
Fools, we MUST heat the planet now, before we die from freezing cold! The sun is reaching a low point in it's cycle, and we are threatened with catastrophy from the coming Ice Age! Only mass-consumption of fossil fuels can generate enough CO2 to save us all from a fate worse than death!
NO MORE BIKINIS!
Aaaaaahhhhh, the pain, the PAIN!
Brilliance doesn't need a sig.
Steven J. Milloy publishes JunkScience.com and is an adjunct scholar at the Cato Institute and a commentator on Fox News.
e n_J._Milloy
He has spent his life as a lobbyist for major corporations and trade organisations which have poisioning or polluting problems. He originally ran NEPI (National Environmental Policy Institute) which was founded by Republican Rep Don Ritter (who tried to get tobacco industry funding) using oil and gas industry funding. NEPI was dedicated to transforming both the EPA and the FDA, and challenging the cost of Superfund toxic cleanups by these large corporations.
NEPI was also associated with the AQSC (Air Quality Standards Coalition) which was devoted to emasculating Clean Air laws. This organisation took up the cry of "we need sound science" from the chemical industry as a way to counter claims of pollution -- and Milloy became involved in what became known as the "sound-science" movement. Its most effective ploy was to label science not beneficial to the large funding corporations as "junk" -- and Milloy was one of its most effective lobbyists because he wrote well, and used humour (PJ O'Rourke was another -- but better!)
He joined Philip Morris's specialist-science/PR company APCO & Associates in 1992, working behind the scenes on a business venture known as "Issues Watch". By this time, APCO had been taken over and become a part of the world-wide Grey Marketing organisation, and so Milloy was able to use the international organisation as a feed source for services to corporations who had international problems.
Issues Watch bulletins were only given out to paying customers, so Milloy started for APCO the "Junkscience.com" web site, which gave him an outlet to attack health and environmental activists, and scientists who published findings not supportive of his client's businesses. Like most good PR it mixes some good, general criticism of science and science-reporting, with some outright distorted and manipulative pieces.
The Junkscience web site was supposedly run by a pseudo-grassroots organisation called TASSC (The Advancement for Sound Science Coalition), which initially paid ex-Governor Curruthers of New Mexico as a front. Milloy actually ran it from the back-room, and issued the press releases. Then when Curruthers resigned, Milloy started to call himself "Director" (Bonner Cohen - another of the same ilk also working for APCO - became "President")
Initially all of this was funded by Philip Morris, as part of their contributions to the distortion of tobacco science, but later they widened out the focus and introduced even more funding by establishing a coalition -- with energy, pharmaceutical, chemical companies. TASSC's funders include 3M, Amoco, Chevron, Dow Chemical, Exxon, General Motors, Lawrence Livermore National Laboratory, Lorillard Tobacco, Louisiana Chemical Association,National Pest Control Association, Occidental Petroleum, Philip Morris Companies, Procter & Gamble, Santa Fe Pacific Gold, and W.R. Grace, the asbestos and pesticide manufacturers.
TASSC was then exposed publicly as a fraud. And so Milloy established the "Citizens for the Integrity of Science" to take over the running of the Junkscience.com web site.

amazing what you find on the internets
Why is it that when these scientists concoct this "global warming" theory they are brilliant and yet when their numbers go completely wrong, they're still brilliant? I'm not saying humans haven't had an impact on the environment, but there is a lot of problems with the GW theory and the media just ignores it. I didn't read all of the posts, but I'm sure there's a Bush reference in here somewhere. This is crap. Keep in mind, people, scientists 20 years ago thought we were headed for a global chill within 50 years.
In a recent National Geographic they say that the CO2 is rising, but the temperature changes through history (from ice cores and other things studied) show that temp changes over time are also tied to changes in the way the earth orbits and we are in one of those changes in orbit right now...

Some one needs to do a sensitivity analysis on all these two.
In 1998 the average concentration of CO2 in the atomosphere was 369ppm.
Decaying vegetable matter is a big CO2 source too. The interesting thing is that organic decay works faster when things are warmer (just like any chemical reaction). For an example, unplug your fridge.
Which creates positive feedback: the more the climate warms,the more CO2 goes into the atmosphere.
There are also some forms of negative feedback and other forms of positive feedback. Putting accurate numbers on them is hard. Getting numbers accurate enough for forecasts is really hard. That's why climatologists talk about ranges and probabilities, and is the reason they're truthful when they say they need more research funding.
Evil Doer!
the current co2 level is around 400 ppm and is currently rising by approx 2ppm per year. Does that mean that in 499,800 years the whole planet will reach 1,000,000 ppm of Co2 and therefore just be a big ball of gas ?

I reset my case.
Seriously, isn't it time people realised that environmental studies is still a discipline in its infancy, and political action taken on the basis of a young science is irresponsible ?
Get with the program, dude. ALL our science is in its infancy. Environmental science is no different than any other science. There is uncertainty involved and if you're not comfortable with uncertainty then you're not likely to be able to understand and evaluate the value of scientific study. What you're arguing is for the elimination of science as a basis for the deployment of policy. That leaves us with only faith to go by. I prefer to use uncertain science as a basis for policy rather than certain faith.

"Gold still represents the ultimate form of payment in the world." - Alan Greenspan, 1999
I cannot find the link at this time, but the scientists who came up with the whole Global Warming research deliberately ignored years in the middle ages where the average temperature in Europe was a lot higher than it is today. Apparently, that data did not fit their theory, so they ignored it.
Another thing to keep in mind is that one of the more recent ice ages was caused by arctic ice melting into the Atlantic, the resulting rush of fresh water causing the warm waters of the Gulf Stream to sink. The glaciers started to move in after only 70 years (a short time in Geological terms).
So, it's possible that this whole warmup is natural, and we're actually heading for an ice age. Freeze or Broil, take you pick, everyone.
I wouldn't worry, though, we'll all be killed in the Nuclear War soon, anyway.

The world will not get better through technology. We must seek to be better people.
Well even if we are really lucky and there is no relationship between climate change and pollution, we should still back off on the pollution.
It's just common sense. Don't shit where you eat, right?
This trend toward polarizing and over-simplifying every issue is really lame. I find it really scary when I see people validating their outrageous consumption levels with arguments like "global warming isn't real". Climate change is just one of many symptoms of industry's impact on this planet that anyone who is paying attention would notice.
Lets find ways to reduce waste soon. Everyone agreed? This is one of those things where "every little bit" does count and there is lots that you and me and the guy next door can do to effect real change. IMO anyone who won't even TRY to reduce their waste is a selfish moron.
For posting Flamebait, and being European.
I want to delete my account but Slashdot doesn't allow it.
Drill some ice cores, take the data back hundreds of thousands of years, and the correlation between atmospheric CO2 and mean global temperature is one of the tightest you'll ever see.
Pick a small subset of some noisy data and you can lose sight of the signal.
Humans are prejudiced to think in terms of atmospheric temperature, but most of the earth's life happens in the ocean or in soil. Temperatures there seem to be rising. Tropospheric temperature measured by satellite is not tracking the rest of the planet. All that proves is that we don't fully understand the climate system.
Since we don't fully understand the system, you can argue that major policy measures are a waste of effort. You could also argue that maybe we shouldn't run an unpredictable experiment like raising CO2 levels on a planet we're trying to use at the same time. Do you change tuning parameters at random on a production server?
BTW the junkscience.com article is mostly good.
Healthy skepticism would be to wonder whether higher temperatures caused greater CO2 levels, or whether they were both caused by something else.
The data provided is probably correct. What one might suspect is bias in favour of a conclusion that will result in increased funding for Mr. Keeling's activities. I have known far too many scholars to not suspect that most of these 'soft' sciences include heavy bias in favour of one side of the issue or the other. If anyone feels like having a quick go at the raw data, it can be found here: ftp://ftp.cmdl.noaa.gov/ccg/co2/GLOBALVIEW/gv/ As you will notice, the variations are rather large, some even to the point that one must suspect an anomaly local in nature. The variations are also seasonally variable. Might this just be part of a larger seasonal variation? Sun spots? Might a scientist secretly have taken up smoking? As it says in the article, the rise is not uniform across the globe, so it might just be local volcanic activity that sets the Mauna Loa meter off. Is this really data we want to use as a basis for banning fossil fuels? And even if the data correctly predicts rising CO2 levels, is the correlation between CO2 levels on Mauna Loa and global temperature reliable? And if it is, will we be able to substantially affect the outcome by using alternate (more expensive) fuels? And even more pertinent: Will China be in on the deal? One billion Chinese who are rapidly reaching the same levels of industrialization as the West might be reluctant to give up higher living standards for that warm, fuzzy feeling that alternate fuels give you. The advantage of this whole scheme would be that we wouldn't have to kill so many brown people when we don't need their oil anymore.
If you believe all this crap, I've got a bridge I'd like to sell you.

Well...you made a statement that can't be proven wrong. It's slick, but misleading. Relative to the other branches of science, environmental sciences are very immature. For the record, what would qualify a branch of science as mature to you? That can't really be quantified in a meaningful way...it's all relative.
We've been dealing with mathematics, for a few thousand years now. We've been dealing with physics for at least several centuries. Metallurgy and chemistry goes back quite a long way as well. We've been studying the C02 levels in the atmosphere for a few decades at most...particularly since we have satellites to give us a better view of it.
I often think about what happens to the petrol that is used by my car. At the moment, I'm a fairly light user of my car. But it doesn't take long to go through 10 litres of petrol.
Once that petrol has been used by the car, it has been converted into gases, and released into the atmosphere. Matter can't be destroyed, so it's not like the petrol was 'used up', it purely changes form, releasing energy. Secondly, a gas takes up a much much larger space than a liquid, and that liquid petrol is turned into gases (and water vapour, which I guess condenses eventually).
Cars burn thousands of litres in their lifetime, and there are millions of cars. I know the earth is huge, but the atmosphere is still finite. I live in relatively small city compared to others (Adelaide, Australia), yet there is often a morning haze over the city from people driving to work. The haze is caused by the exhaust from cars reacting with sunlight, etc... No-one seems to think that it's a problem as it eventually drifts away with the wind. Out of sight, out of mind. But the gasses are still up there!
The fact that we are not seeing more of a greenhouse/atmosphere problem I find amazing.

I guess this is the oppositeScroogle
Having been involved with the Oklahoma Anthropological Society the last several years; and we work closely with the Oklahoma Archeological Survey. I have learned that at least for Oklahoma the climate goes through dramatic changes about every 1000 yrs or so. I can also tell you from the archeological record there that Oklahoma is about 30 yrs over due for a Major Drought that will bring Sand dunes as far east as Oklahoma City. The point being the Earth goes through dramatic climate changes on a regularly scheduled basis. IE yes the earth is getting warming, but it is right on schedule doing so. Man Kind has little to do with it. Note: If you listen to NPR for news, well that just lets the rest of us know your political views. 1) Your a John Kerry Supporter 2) You hate George W Bush 3) You hate Capitalism 4) Vladamir Lenin is your Hero 5) Fidel Castro is your Uncle 6) Your so far to the left you couldn't see the right if you wanted too.
"If we make it a little faster, then we just eliminate ourselves as a species a little faster, something else will take over eventually."
You hear this kind of statement (or at least I have...) sometimes when talking about climate change. "climate varies over time" and "these things happen in earth's history naturally".
Man, who cares if it's a natuarl phenomenon if it still kills us dead? I don't give a crap who did or didn't CAUSE the global catastrophe. I just don't want it killin my ass off. "Humans are / aren't to blame" -- who cares?
Look - the goal here is to prevent me from being dead. Seriously. I just got married and my wife would be super pissed off if the world got all screwed up just after she got a hold of the plates she wanted. And I've made her pissed off a few times, trust me it's no good.
Perhaps the climate is fluctuating normally. Perhaps it's humanity doing it. Maybe all the cows farting in the fields are doing it. What we need is to try and figure out if we can control it. If we screw up the environment then my wife is just gonna start tearing around the country kicking people's asses.
If you ask the Florida folks that is being hit by ever increasing Hurricanes I would say Yes, but they indirectly decided to scrap the Kyoto accord so on balance I would say no it doesn't matter.
Help fight continental drift.
First, over 95% of the greenhouse effect is due to water vapor - not greenhouse gasses. While Carbon Dioxide is the largest contributor to the greenhouse gasses that make up the rest of the greenhouse effect, the human contribution to this is estimated somewhere between 0.2% and 0.3%. The impact of the Kyoto Protocol will have only about a 0.04% effect on the total greenhouse effect. Natural changes are much more significant.
Furthermore, the greenhouse effect is only one minor factor in the global warming equation. Bigger factors are due to precession and eccentricity of the Earth's orbit, changes in axis tilt, plate tectonics, and solar fluctuations. Global warming periods are a normal "feature" of our planet's life cycle, as are ice ages. If you want to have a real impact on global temperatures, you probably need to do something about that pesky gravity that's really causing all this havoc.
However, before you run off and stop global warming, you might want to reconsider. The Earth is about 5 thousand years overdue for it's next ice age...
Finally, realize that one man's science is another man's bunk. While it is true that many scientists are measuring increases in global temperatures, you should understand that this is based on a sampling methodology where temperatures are measured at various "accessible" sites, but not uniformly around the globe. An alternate scientific method uses satellite thermal imaging to measure the overall global temperature trends. Satellite measurements show that we are actually in a cooling trend. Who's science do you choose to believe???
There's a lot of good reasons to cut fossil fuel consumption, but global warming is probably not one of them. Plus, whether we are headed for a roast or the big chill, there's very little that we can do about it... In the immortal words of Douglas Adams... "Don't Panic!"

You know, burning oil pipelines and cities *do* produce some CO2.
Wonder if that has something to do with it?
Look, this thing is totally safe! Built it myself, you know. You just press that button like this and then turn that lev
Like I said before, the Larsen B Ice Shelf in Antarctica collapsed in 2002, and exposed glaciers have had accellerated movements and melting. Could all this melted ice have affected the carbon sink capacity of the oceans, since this unexplained leap in CO2 coincidentally started around the same time?
Oh, and I just watched The Day After Tomorrow on DVD, and it was all about cataclysmic natural disasters, and the movie began with the collapse of the Larsen B Ice Shelf. Coincidentally, I watched it after my previous post about the ice shelf, without knowing the movie was going to mention it. Kind of wierd.
But I guess when that's all you have left to fight with, it's what you use.
Look at China's booming economy and their insatiable demand for oil driving rates up to insane levels and devouring all supply.

It has been tried recently. Despite what lab results may suggest, it turns out that in reality, adding iron salts to the sea removes less CO2 than is generated by the ship that is used to transport it... doesn't sound like a viable solution to me.
> Why are environmentalist opposed to a scientific solution?
Because they may in turn also have unexpected and undesirable consequences themselves, or indeed carry a risk that they may make things worse in the long run?
E.g. we could bury liquified CO2 in the oceans or in deep mines, as some oil executives suggest, only for it all to bubble up in a few decades time as the temperature rises, or because of natural landslips, leading to local suffocations and dramatic increases in global temperatures. (There are precedents with natural, underwater C02 and methane deposits in lakes in Africa, where entire towns and villages have been suffocated as a result.)

Some scientists are in it for the greater knowledge. However, for many it's just another effing career and they are just as political, just as scheming, just as corrupt, and just as human, as the population they come from.
Do a little effing reading in the atmospheric sciences. Pay attention to the grants and contracts while you read. Look at who gets paid for what and then re-read with a critical eye and see how many are seeking evidence to support the idea of global warming rather than taking an objective view of the data.

Yeah. That's right. Better safe than sorry. Don't fuck with the earth dude, you don't know what the hell you're talking about
Sure, we don't know what Normal levels are. But what if you're wrong, and the normal level IS a stable level. Then we're fucked.
We cannot claim to have altered the cycles. Therefore, we cannot claim that we can claim that we have not affected the cycles.
You see, it goes both ways. You can't just say "Oh yeah, we don't know if we affect the cycles" without also saying "We don't know if we don't affect the cycles."
That's why your argument is so much bullshit.
Scientists are often right at predicting physical outcomes. Who'd have thought that all that "relativity" mumbo jumbo actually worked? Of course it did for atomic theory and nuclear bombs? When people criticize scientific "theories" for being useless because "they are just theories" I can't help but think of atomic theory and the politicization of science. When science is politicized, as it was with Nuclear physics, (and as it is now with Climate), disasters occur.

I don't know s**t about science, or the atmosphere or anything else related to this CO2 level thing. But I can tell you this: I am tired of hearing all these cries from scientists about global warming and CO2 levels, and all this other stuff.
First, if I remember correctly from grade school, humans have been on this planet for an very small fraction of the earths "life", so how can they even pretend to assume they have any clue what is going on here?
Second, a decade here or there does not a trend make - especially when you are talking about such a huge amount of time.
Can't someone just say, "This is weird, the CO2 levels have risen quite a bit but we have no idea what that means, we'll have to watch it over the next 100 years to see what happens"
Oh, and for those of you who are going to tell me: "We have to be cautious, and make sure we don't harm the planet" I say, If the planet doesn't like what we're doing we will be killed off - perhaps along with all other life as well - and the planet will slowly move back to an equilibrium. Done deal.
"Oh, you hate your job? There's a support group for that, it's called everyone, they meet at the bar."
There's an overwhelming amount of biased moderation going on in thread, more than is usual even for a global warming debate.
Can mods please stop shooting down well written and insightful arguments from the other side? What are you afraid of? being convinced?
The tundra is releasing huge amounts of methane and carbon dioxide now, from microbial processes. Plus, as the oceans warm up, increasing amounts of methane gas are released as the molecular methane bound in methane clathrate ices is freed by melting. Just to give an idea of how this is changing the atmosphere now, Summer temperatures at the North Pole were 15F warmer than normal -- just a few weeks ago.
Right now, these newly-active natural sources of GHGs (Greenhouse Gasses) may exceed the amount of industrial GHGs being produced. The process is certainly self-reinforcing, and the feedback loop is now fully established.
It's no longer a matter of turning off lights and buying hybrid cars. Global Warming will not stop until the natural mechanisms now producing it stop. We should manage the energy sources we have as best we can, but there's nothing we can do about climate any time soon.
Since the time that the Earth formed a crust, the planet has been bi-stable in terms of climate: either hot or cold, stadial or glacial. The balance has been seriously threatened about half a dozen times, AFAIK: During the early Proterozoic "Iceball Earth" episode 2.3 BYA; during the pre-Cambrian Vendian period, 900-600 MYA, 4 glacial epochs; and during the Permian extinction (251 MYA). Why the climate recovered, I don't know, but it did. But this time, if we keep pushing the atmosphere with increasing amounts of waste heat and heat-trapping GHGs, we could push it beyond its ability to recover at all. No one knows what that point is, but within a few centuries of it starting, the surface of the Earth would be too hot to support life.
We started the ball rolling, but now it's gotten beyond our control. If we survive this era, I hope our decendants learn not to do what we have done.
The rise in CO2 is because GWB's disasterous policies - his "clean air" iniatives set 'target levels' but mandated no _enforced_ levels, infact it repealed enforcement of almost all clean air standards from previous administrations.
If you cannot keep politics out of your moderation remove yourself from the Mod Lottery.. NOW!

If we don't know for sure it would be a good policy to be cautious.

How do you prove a tipping point in a complex system? If you're looking strictly at statistical variations from the norm in a complex system the variations in any one element prior to calmity can be quite small initially. It's a little like trying to predict the butterfly effect.
I certainly wouldn't be so quick to dismiss a 4 ppm increase as insignificant because it falls within the range of monthly variations. If that turns out to be a sustainable average increase the previous author's suggestion that our first real indication of trouble could be plans to relocate Miami are not inconceivable.
I'd also remind you that it wasn't that long ago that the suggestion of the scientifically valid possibility that the Earth could experience an extinction event caused by a giant rock falling out of the sky would have not only been ridiculed by their fellow scientists, but the author might well have been burned as a heretic.

Furthermore, you didn't address my point - is taking (political) action on basis of flawed data and models responsible ?
See what you did there? You used a loaded word ("flawed") to describe current science. By your use of the word, life itself would be considered "flawed" because it is filled with uncertainty. It's as impossible to remove all uncertainty from science as it is to remove it from life itself. Use some wisdom instead of twisted rhetoric.
- Hail to our fearless misleader! Fool speed ahead!
Someone will be along soon to tell us that this is all part of a natural progression and we have nothing to worry about and to all go back to driving 5.0 SUVs as we can't hope to understand the climate and so figures are irrelevant and its not are fault etc etc etc. I wonder how many of these people STILL have their heads in the sand after this?
It just makes you feel *so* smart and superior to type that, doesn't it?
Hate to penetrate your smugness, but we still don't understand the dynamic systems of climate. And unless you were typing that on some sort of birch bark, nuclear powered computer (hey, no CO2!) you might want to tone down the superiority complex.
Do you have any ideas, other than lousy, inequitable treaties, or full-of-it smugness?

We know that humans have slightly increased CO2 levels in the atmosphere
Actually, we don't. We do not have an accurate record of what 'normal' CO2 levels are, so we cannot even say *if* CO2 levels have increased.
Actually we do. While it is true that we don't know exactly what normal levels of CO2 are, we have some pretty strong evidence that we're about as high or more likely even higher than it has been in the last 1/2 million years. Even ignoring that, we can still detect the influence that humans have made on the amount of CO2 in the atmosphere.
Where the evidence? Look at the cosmic rays. They are continually produding C13 and C14 at the edge of our atmosphere. This carbon also gets mixed into the carbon cycle, going in and out of available sinks. Lets just assume for now that fossil fuels were created several millions of years ago. The C13 locked in at that time has all but disappeared because C13 decays relatively quickly. So what happens if the to the relative amount of C13 in CO2 as we burn up C13-depleted fossil fuel. Bingo. Less C13 in the atmosphere. Set against any changes in the cosmic ray background, it's a done deal. It has been measured, and it is a simple undeniable fact that humans burning fossil fuels are increasingly responsible for at least part of the increase in the amount of CO2 in the atmosphere.
Here's a nice carbon cycle explanation for anyone who's interested http://seawifs.gsfc.nasa.gov/SEAWIFS/LIVING_OCEAN/ TEACHER4.html] A google will throw up lot's of information about C13 and C14. (The latter can also used as evidence to bolster the measurements.)

Quote from Dr. Piers Foster of Reading University: 'If this is a rate change, of course it will be very significant. It will be of enormous concern, because it will imply that all our global warming predictions for the next hundred years or so will have to be redone.
Because him having to recalculate his models is the biggest concern, I'm sure!
/John Sjolander, project manager Contribio
So what you're saying is: "They've increased because they must have". That's a great argument.
I think you missed the logic train. "We put out a lot of CO2" does not in any way, shape, or form mean that "The global level of CO2 is increasing because of us". There may be natural fluctuations which we are nowhere close to understanding and which would completely automatically dwarf anything put of by humans.

I grew up in Pennsylvania and now live in Connecticut. It is true we've had a few cool years. Global warming projections specifically point out that some areas will cool - at lest for a while.
If you take the time to examine weather patterns, you will notice that New England is not getting the Jetstream southern dip effect lately. This means the stream is not dipping into the tropics (Gulf of Mexico) and up the east coast. This is why we are cooler.
You'd also notice that the west continues to be unusually hot and dry. You'd have to be under a rather large rock to not have seen the massive forest fires throughout the west in the last five years or so. This year, they started in May, when the usual expected period starts in August.
Our oil-coal-nuclear-timber industry run government is responding to these fires by "thinning the forests". That is, logging wild forests nowhere near communities. Brilliant.
You'd also notice that the weather pattens are pushing warm air into the arctic. Guess what? If you push warm air into the arctic, where does the cold air go? - SOUTH!!! In this case, into northeastern United States.
We here in the U.S. of A. need to take our collective heads out of our extremely fat asses and take a look around. Stop listenning to soundbites from our government and start researching the truth (or lies) behind them.
To our friends across the globe, I can only reassure you that we the people of North America are not all clueless, but we do seem to be powerless in a democracy that is going awry, and awash in Orwellian newspeak. I am truely frightenned for our country.
Following your logic, we'd be restricted from doing almost *anything* - based on the simplistic concept of "Well, we never had a problem with item X before people started doing item Y - so let's seriously investigate stopping item X!"
It seems fairly obvious to me that the planet is still operating just fine. The only "signs of a problem" we've received are some scientists spouting *theories* based on watching numbers changing by a few parts per million.
Meanwhile, just as many scientists are arguing counter-theories cancelling those theories out. This hardly sounds like "cause for alarm" to me.
We've already spent many millions on reducing CO2 emissions at power plants, among other places - and yet nobody seems to be able to show evidence of any improvements from it.
We get to choose between 2 idiots this year. I sure wish we had a better choice too.

Even if the icecaps melt and the earth gets flooded, people would still say "I don't think we have enough evidence" and "The earth used to be this hot a billion years ago, so stop complaining" and "These scientists are just trying to get more research funding", and "It's just a natural phenomenon we can't do anything about it"
It is amazing how people will ignore the whole scientific community in favor of several more pleasant sounding lies told by opportunistic politicians.

Unlike you and many of the American population who demonize science and those who follow it, I trust these scientists to follow the scientific method and monitor the situation of the world.
This is not a joking issue. This is serious. It is not an issue where we should be panicking and running around like chickens with their heads cut off. This needs reasoned thought and we need to listen to the people who are capable of it.
Sadly, most of the population of the United States is incapable of calm reasoning and sound logic (ha, when was the last time that was taught in public schools?)
Just because it tells you something you don't want to believe doesn't make it untrue, or unimportant.
I still find it amazing that science has gone from being worshipped in the '50s to being demonized in the 21st century. It's cool to be the bully, but not to be the geek...
P.S. The Day After Tomorrow was a total flop and no amount of handwaving is going to get people to buy it.

-------
Information piece ONE:
Measurements of CO2 in the atmosphere have been continuous for almost 50 years at Mauna Loa Observatory, 12,000ft up a mountain in Hawaii, regarded as far enough away from any carbon dioxide source to be a reliable measuring point.
In recent decades CO2 increased on average by 1.5 parts per million (ppm) a year because of the amount of oil, coal and gas burnt, but has now jumped to more than 2 ppm in 2002 and 2003.
------------
-------
Information piece TWO:
Peter Cox, head of the Carbon Cycle Group at the Met Office's Hadley Centre for Climate Change, said the increase in carbon dioxide was not uniform across the globe.
Measurements of CO2 levels in Australia and at the south pole were slightly lower, he said, so it looked as though something unusual had occurred in the northern hemisphere.
-----------------
Our first piece of information is that CO2 levels have gone remarkably up at one observatory. Our second piece of information is that CO2 levels have gone slightly down at two other observatories.
How come that everyone exclaims information piece 1 as "the big news"? How come that people discuss information piece 1 to the exclusion of information piece 2?
Most interestingly, which guidelines do newspapers follow when selecting which information piece to base a headline on? Are these guidelines publically available?
It will be of enormous concern, because it will imply that all our global warming predictions for the next hundred years or so will have to be redone.
Redone, redone! The world is ending (according to the dire media predictions) and you're worried about having to redo your prediction of when it happens?
--Where are we going? And why am I in this handbasket?
People ignore the "scientific community" because they have been desensitized by the steady stream of dire predictions that appear in the press. In addition, the remedies recommended are always some way-out impossibility. Stop driving your car to work, stop eating, stop breathing.
p.s. the ozone hole is smaller this year. too bad nobody saw fit to put that in the newspaper.
4 years of a dazzlingly stupid drunkard (okay, I know he's just stupid, but he seems drunk) at the helm of the world's largest polluting country, arrogant flouting of the Kyoto protocol... who can honestly be surprised that we've seen a leap in CO2 levels!
'bout fucking time. Speaking of fucking. Since we are going to all die because of global warming, it's time to get laid.
Scripps did a study of microbe skeletons in ocean floor layers. From the skelitcal remains they showed that indeed there is more co2 in the atmosphere today than in the past. The graph was very cyclical with peaks of the same magnitude for thousands of years. The chart shows a spike beginning at the industrial revolution that is larger than all the preceeding peaks on the chart. They took core samples off the coast of south america.
I think its the problem is a rate game. The rate that the environment can process back the co2. eg. acid rain reacts with the earths surface. Or acid reacts with all the metal in the sea sand or other materials like lime. ( stick a magnet in the sand ) If the production rate is higher then we have accumulation.
16 of the 20 most polluting cities are in China. I saw an article yesterday that France signed a multibillion dollar deal with China to build industrial equipment. They were going to invite president Chirac to an airshow. But they had to cancel the airshow because the atmosphere was at a toxic level. Most people were told to stay indoors. Most of that c02 comes from chinese peasants burning coal pallets to stay warm. Most of the new Chinese cars have low emissions standards. Also, the massive demand in China is driving up commodity prices like oil.
My question is simple: How many of the people saying "No conclusive proof means stay the course" are Libertarians?
And how many of the people saying "No, wait a minute, perhaps human activity is the problem" are Libertarians?
I'm very curious to know if Libertarians are more apt to think that manmade CO2 emissions are a problem or aren't.
I don't understand Libertarianism at all and this is just an attempt to get a better understanding of you creatures.
Yes, I agree that Global Warming could be beneficial. While we may lose some cool places like lower Boston, New Orleans, San Francisco, etc. we will also have the great benefit of losing Hollywood and Florida.
If only Utah were near the coast, then I would buy a Hummer and commute 50 miles to work everyday just to hasten that great day!
Don't worry, it all balances out.
More CO2 means more plantlife growing that will give off O2.
This just more of the same old, "The sky is falling!" crap that we hear year after year without much consideration for the bigger picture.
Is that no one who seems to be speaking out about the rising levels of carbon dioxide in the atmosphere and the possible effects on the "global warming" phenomenon seems to think about the issue in a truly critical manner.
For one thing, I personally don't believe that the rising concentration of carbon dioxide is really having all that much effect. I think the CO2 issue is merely a symptom of what is actually causing the average temperature to rise.
Here's the kicker--why is it that no one really seems to be talking about all the waste heat that the human species tosses into the environment as a direct result of our ever-increasing consumption of energy in all its forms?
The Kyoto Treaty was *not* the answer. That's why the US effectively pulled out. No long term solution to global warming can be effective if the rapidly expaning economies of countries like China and India do not accept the same committments we do. Yes, right now the US consumes more. That will not be true for very much longer. While the US does, indeed, need to reduce it's per capita consumption, we all need to make sure that no other country ever even approaches current US levels of consumption. This, of course, does not sit well with developing nations, but perhaps they should be more concerned about learning lessons from American failures than trying to duplicate American excesses.
Look, a modern Hummer engine puts out less emissions than much smaller engines of yesteryear. But it still produces an amazing amount of waste heat!
We cannot ignore this issue any longer. The only answer is, we need to stop using so much damned energy!
Yes, right now, the US is the biggest problem--and the US's problem will be particularly difficult to solve, given the profligate nature of most US citizens. It is sad to see that in a time when the US needs the help of the global community the most, the Bush Administration has chosen to erode our moral position even further by squandering much of the trust we have been able to build in the world.
None of this is to say that carbon dioxide does not contribute to global warming by trapping heat in the environment--but CO2 is not a source of heat, and the environment's ability to cope with increased levels of CO2 is very great. The real problem is that we've created a positive feedback loop here--more energy consumption causes more heat and more CO2, more CO2 helps trap more heat, especially from a heat source which we cannot control. Reducing consumption *will* reduce CO2. Reducing CO2 without reducing consumption will not have enough of an effect to matter.
Technology cannot solve this problem. Conservation is the only answer.
PS: I apologize for my lack of ability to produce a subscript...but there's only so many times I can type "carbon dioxide" without getting bored, and you know what I mean...

A lot of the people that don't want to believe in "Global Warming" aren't against the idea that the Earth is increasing in temperature, just that humans have a measurable impact on it. We are insignificant compared to the natural processes of the planet alone. The temperature on a geological timeline moved up and down "A LOT" (technical term) and since we've been running around with R12 and chain saws it's been pretty stable. But, it's way too soon to say, oh yeah WE doomed the planet... Everybody hold your breath and read your Junior Skeptic magazine or plant a tree or something. ;)
The end of the world has arrived. And its about time. I was getting bored waiting for it. Hurricanes, volcanos, Supermans death,all portent the end of our time.
Uhh, wouldn't the scientifically responsible thing to do before publishing this fearmongering tripe have been to go MEASURE the CO2 in the ocean to see if indeed it has absorbed as much as it can?
Here's what is likely causing the increase in CO2:
1) China is consuming oil and burning it as fast as they possibly can.
2) The world economy is picking up, which naturally causes the world to need more energy, which it gets most of from burning fossil fuels
3) Massive wildfires have contributed massive amounts of CO2, albeit temporarily, while at the same time reducing the amount of plant life to absorb it. (this will negate itself when the plants grow back)
All of these have happened in the last two years, especially #1, that could easily explain a quick spike in CO2 levels. Scientists are not supposed to jump to conclusions.
Speaking of reliable measuring points, FTFA:
"Measurements of CO2 in the atmosphere have been continuous for almost 50 years at Mauna Loa Observatory, 12,000ft up a mountain in Hawaii, regarded as far enough away from any carbon dioxide source to be a reliable measuring point. "
Uhhh, isn't a volcano a huge source of CO2? It's there an active volcano somewhere in hawaii? Did they look at any possible shifts in the prevailing winds that might bring in CO2 from another source?
Also FTFA:
"It is possible that this is merely a reflection of natural events like previous peaks in the rate, but it is also possible that it is the beginning of a natural process unprecedented in the record."
Uhhh, isn't this a completely speculative non-statement? It's also possible that aliens have dropped a CO2 bomb somewhere on the planet in order to suffocate us and take over. It's also possible that monkey are about to fly out of my ass at hypersonic speeds. Of course, part of the scientific process is speculating as to why things happen, but this is just pointed fearmongering.
"Dr Keeling said since there was no sign of a dramatic increase in the amount of fossil fuels being burnt in 2002 and 2003, the rise "could be a weakening of the Earth's carbon sinks, associated with the world warming, as part of a climate change feedback mechanism. It is a cause for concern'."
This is a blatant LIE. The price of oil would not be twice what it was 3 years ago if demand had not increased dramatically. As with any economic upturn, energy consumption NECESSARILY increases. Ergo, more fossile fuels MUST be consumed to generate that energy.
Tom Burke, visiting professor at Imperial College London, and a former special adviser to the former Tory environment minister John Gummer, warned: "We're watching the clock and the clock is beginning to tick faster, like it seems to before a bomb goes off."
More blatant fearmongering. There is no scientific evidence to support any of the things they are trying to scare you with.
The article FINALLY starts to make some sense after the point which most modern ADHD people would have stopped reading:
Measurements of CO2 levels in Australia and at the south pole were slightly lower, he said, so it looked as though something unusual had occurred in the northern hemisphere.
"My guess is that there were extra forest fires in the northern hemisphere, and particularly a very hot summer in Europe," Dr Cox said. "This led to a die-back in vegetation and an increase in release of carbon from the soil, rather than more growing plants taking carbon out of the atmosphere, which is usually the case in summer."
Finally some speculation that is direct, and could make sense with the proper research, stating some SPECIFIC possible causes rather than just "oh this could be very very bad!"
So, after pages of FUD on "global warming," the article finally closes with a spurt instead of a bang:
"Based on those two years alone I would say it was too soon to say that a new trend has been established, but it warrants close scrutiny."
well DUH... talk about people just trying to get published somewhere...
Jeez...
political action taken on the basis of a young science is irresponsible ?
And political inaction on the basis of "well hey, it might not happen" is what exactly?

the weather has been interesting. Very warm summers, but more extreme winters. (How does that play into the picture?)
My 80 year old Grandmother has an interesting take having to do with cycles. She does not see anything different yet, unless the current cycle does not end...
She says it works on about 11 year swings.
I know, not scientific, but I thought her perspective interesting. (Yes, we did talk about this 'whole dang global warmin thing' a while back. She is old, but still very interesting to talk to. Her favorite new tech: Cell Phones and VCR +. Does not use the computer at all however. "Why bother when you can just call?"
My own take is that we don't really have a good picture of our environmental trends yet. For all we know, we could just be living in a brief (on cosmic scale timelines) period of stability that we have little control over. Of course common sense says burning lots of things combined with the diminished forests has got to do something...
Guess I am just rambling this morning --need coffee... I don't see a warming trend, but I do see greater temp. extremes similar to those about 10 years ago here. (Hmmm.. maybe grammy might be right)
Blogging because I can...
Oh know the world is going to end.
Get a grip on reality. The planet has been here alot longer than all of us and it will be here even after we are long gone. This global warming stuff is just alot of FUD by some scientists that want the spot light. Just look at the history and you will fine that the planet has gone thru far worse cases than abuse by us humans.
Maybe that CO2 increment could be related to the Global Dimming effect.

We've got bigger problems than "terrorism" and "perscription drugs" (all of which will go generic in about 20 yrs.) I wish we had visionary leadership that would deal with the real problems we've got. I am sick that we have to import oil from the Saudis, decently efficient cars from Japan, and get our nuclear fuel reprocessed in France. And hitchhike our way to the spacestation on Russian rockets. We've gone from the scientific leaders of the planet to a bunch of sissified head-in-the sand consumers.
Or maybe it's just Monday.
His conclusion that the warming of the planet will greatly accelerate the release of carbon from the soil, which in turn, will warm the planet, which in turn will release more carbon from the soil. As you can see, he predicts a nasty spiral.
One way to drastically drop the carbon level is to seed the southern Pacific ocean with small amounts of iron. This has been shown to cause an algae bloom, drastically increasing the sinking of CO2 from the air. (A major fraction of the algae die without being eaten and sink, taking the carbon with them to the deep ocean where it sits for millenia until the sluggish currents bring it to an upwelling.)
If we have a runaway we can try using this to turn it around. Attempting to fine-tune the carbon content of the atmosphere with it now risks the opposite spiral and a new ice age:
- Carbon sink lowers the C02 level and greenhouse effect.
- CO2 drop produces global cooling.
- Cooling results in more glaciation on Antarctica and the polar extremes of the other continents.
- Sequestered water and cooler temperatures reduce rainfall.
- Reduced rainfall expands deserts.
- Expanded deserts result in more dust in the atmosphere, including iron and other micronutrients.
- Some of this dust falls in the ocean, reenforcing and expanding the algae blooms.
There is currently some question as to whether this, rather than (just) solar cycles or continental drift modifying weather cycles, is the cause of ice ages.

article says: "Measurements of CO2 in the atmosphere have been continuous for almost 50 years at Mauna Loa Observatory, 12,000ft up a mountain in Hawaii, regarded as far enough away from any carbon dioxide source to be a reliable measuring point."
Well perhaps Mauna Loa is no longer "far enough away from any carbon dioxide source to be a reliable measuring point." I'd like to know what's changed in that area in the last two years...
1. We aren't likely to destroy a planet. At most, we're going to change its atmospheric composition and climate to the point where it is no longer a viable environment for many of its current species, including ours. However, more than likely we will continue to thrive as a species, and will merely be forced to operate at a lower level of technology, and/or in a different geographic range.
2. Most people who are concerned about global warming are also concerned about the global dominance of America, oil companies, and so forth. These interests vitally depend the current geographic range of the human species, and its current social behaviors including the use of technology.
3. Problem solved. Just wait.
Now, if you are concerned about your own prospects as a competitive individual within the species, you should consider what the change in range and/or climate is likely to do to you, and plan appropriately (since you, uniquely or at least ultimately among species, have that capacity).

Hmmm.... Sudden rise in CO2 in the atmosphere... start of the USA Presidential election campaigns... I think I see something here...
Amazing coincidence! I'm a 'computer' scientist and informed and I'm convinced from all my research into the subject that we are on a course with disaster. Any other scientists care to comment?
Did he inhale?
This is of course just FUD. From the tones of the article, the scientific incorrectness, powered by frightening language trying to cover the fact that the data shown just is not so different than what we're collecting since years, it should be clear that this is FUD.
This is not to say that climate should not be studied more in depth to discover the real links between CO2 levels, human population, global and local temperature changes, etc, but as for now very little is known, and very little is certain about all these links.
The problem to find causes and consequences in climate study is really hard so beware of "this is the answer / this is the evil cause" assertions.
Just my 2c.
Yeah, there's a book by that name, too. All the CO2 alarmist stuff is actually pretty decent, in my opinion. I'd rather see us not using oil from any other countries (or "energy" in general). I guess they need the money for funding all their advertisement, so we should all donate to Greenpeace.
We'll do just like in Sid Meier's Alpha Centauri.

They take the data from here:
http://cdiac.esd.ornl.gov/trends/co2/graphics/v
Which are extrapolated atmospheric CO2 measurements from the ice core in Antarctica, and then tack on the modern CO2 measurements from the actual atmosphere in a different climate.
That they don't even mention the caveats of this dangerously speculative merging of incompatible data sets makes it clear that they are more worried about convincing you than finding the truth.
The two methodologies (trapped CO2 measurement in ice vs CO2 measurement in the atmosphere) cannot be merged like this, even discounting the vast differences in climate between Hawaii and Antarctica.
For failing to mention glaring caveats that should be obvious to anyone with a critical scientific eye, I have to dub this alarmist propaganda which is informative and interesting, but not empirical.
Never never stop reading. Always keep on reading. Always listen to arguments from both sides and evaluate them on their own merits and compare them. Always keep a lookout for new arguments for both sides. This is a quite young area in science, not all rules and formulas are known. And when the formula is known the parameters are not certain, resulting in a wide range of results and predictions. More is known every day, but until we have a solid comprehension of the environment, nobody can speak on the subject with 100% authority.
This is not a trivial issue. What happens in the others' backyards may come to haunt you. Never stop reading.
Isn't that when the Hummer 2.0 came out? :)
Do not stare at the sun. It might hurt your eyes.
But, if the "solution" for the problem is to implement a "sustainable" carbon cycle on the planet, there are some pretty significant changes coming down.
First off, can we take it as a given that all practical forms of energy use produce undesirable byproducts? OK, I suppose a windmill does not produce many, but it is difficult to envision the current electrical consumption being supported by wind power. Solar (PV electric generation) in a large scale will produce far more pollutants than any other generation methods except perhaps nuclear - just from manufacturing the cells in large enough quantities.
The question then becomes can we continue with current energy use levels? Wouldn't seem so. The main problem isn't just pollution - it is the waste products from energy use. CO2 is one of those. Heat is another. If the target is "sustainable" we need to look at the effects of using any form of energy over hundreds of years. Simple - if we were using sunshine as the only energy source at the same levels the planet is consuming energy at this would cause serious side effects. So, the answer must be to reduce energy consumption - not decrease energy "wastage" or increase efficiency, but actually decrease consumption. This is the only effective long-term answer.
I think you can pick a date between 1800 and 1950 where energy use became "unsustainable" over the long term. If nothing else, the waste heat from this energy consumption would spell the end for the planet. Therefore, if the goal is to have a "sustainable" environment we must reduce the energy use to those levels which will allow natural processes (heat radiation to space, carbon recyling, etc.) to cope with this energy use. Some improvements can be obtained by greater effiencies available today than were available previously, so we can actually choose a date at which previously unsustainable energy use was taking place and still be able to have a sustainable environment. However, it is not possible to make this up at today's levels. This would entail a world population of perhaps 10 million at most with a comfortable lifestyle. It might be possible for the population to be as high as 50 million, but these people would have a low life expectancy and live in conditions that could only be described as abysmal - something like Bangladesh today, or worse.
The threat is clear - if we want to choose a sustainable environment, we need to begin implementing population reduction measures immediately. There are just too many people to reduce the energy consumption levels to that which could possibly be sustainable. Anyone that says differently is deluding themselves. At the current world population level we would need to kill more than a million people a day just to make a dent in the problem, and even at that rate it would take nearly 20 years.
The other way to look at the problem is that energy use isn't sustainable at a planetary level and resources from outside are needed. We have the technology and skills to move in this direction, but it would require some understanding that this was actually necessary for our survival. I don't think we are there, and universities are churning out people that believe we must be sustainable within our planetary environment. Do you think they understand the population problem? I don't.
Tell Smith to stop breathing on the detector!
There have been attempts to reconcile the two sets of data, mostly having to do with the difficulty of maintaining calibration of the satellites. These tend to produce corrected satellite records that agree with the larger warming measured on the surface, but the jury is still out.
Hmm how about a Southpark one?
Darryl Weathers: How the hell is global warming gonna cause an ice age?!
Chet: Well you know, the... global warming could bring on, like, a climate shift or somethin'?
Darryl Weathers: Chet you are a fuckin' retard, you know that? Even if global warming were real, which all proven scientific data shows it isn't, it would take millions of years for a climate shift to happen. You think at ice age can just happen all of a sudden-like?
Chet: Well I was just tryin' to be helpful.
Darryl Weathers: Well help yourself to a fuckin' scence book, 'cause you're talkin' like a fuckin' retard! Now come on people, we've got to think! Damnit, they took our jerbs!
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
We should just sit back, throw up our hands and do nothing about it? "It's God's will that the Earth get warmer, nothing we can do." The fact is, it doesn't matter why the Earth is getting warmer or why there is more CO2 in the air. The actions we need to take remain the same.
We can't afford to just wait and see. We need to start doing something to reverse the trend or the costs will be catastrophic. The causes don't matter and the facts are indisputable: the Earth is getting warmer and there is more CO2 in the air.
- None can love freedom heartily, but good men; the rest love not freedom, but license. -- John Milton
When I read thread about this topic I see that some people present evidence of global warming and other denouce that there is no proven correlation between xyz (in this case CO2) and temperature rising or something like that.
For what I undestand there is no certainty or proof that the temperatures will rise fast and provoque many damages so many people feel that's not the time to act ('cause acting means $$$).
However during theses discussions I rarely see people saying that there is absolutely no problem and everything is fine. I would says that people disagree more on when we should begin to act.
In my opinion, we should not take the risk of inaction when our habitat in only planet is en danger.
So, by your reasoning, every time the media runs a story about a satelite in orbit, they should also have someone from the Flat-Earth Society on for balance? We might not be able to model the entire atmosphere, but our thermometers work pretty well. Global Warming is a fact: things are getting hotter.
As for modeling: asking to model the entire atmosphere before you accept a global warming explanation implicating CO2 levels is like asking for a model of every particle in the solar system before you accept a model of planetary mechanics that implicates gravity. Using the word 'PROVEN' in big letters like that shows that you don't have a strong grip on how science works, or how good public policy is made. Science (and this holds in both Popper's and Kuhn's account) is inherently provisional, and doesn't admit anything resembling capital-P proof, let alone the all-capitalized proof you want.
And as far as public policy goes, when the potential consequences are so catastrophic, and when the system has such a lag in it, it's irresponsible to quibble over absolute proof: by the time the proof comes in, it'll likely be too late to do anything. Good public policy manages risks, and with climate change, the risks involved with twidding our thumbs while we wait for enough evidence to satisfy petrochemical executives are simply too high. There's a clear scientific consensus on the issue. That's all the balance that we need.
Highly localised anomolies are not that unusual. You get temperature inversions, for example, in many places. Where this coincides with a city, this produces some of the most evil smogs. Aside from the fact that this isn't good for the inhabitants, it probably traps a good deal of the heat in as well.
You've also got to consider that different molecules absorb at different frequencies. Thus, the infrared (ie: heat) given off by direct reflection from the ground is going to be different from that given off by sulpher dioxide, nitrogen dioxide, ozone, and other pollutants. the pollution is going to absorb some of the radiation and then re-radiate it at different frequencies.
What this means is that the temperature of the troposphere is not a good measure of what is happening overall. There are just too many variables. Localized effects, changes in frequency, etc, mean that trivial analysis is not going to produce useful results.
Sure, I'm certain this has all been thought of before. Climatologists aren't stupid. However, they don't exactly have the kind of budget you'd need to build a network of comprehensive sensors to scan all layers of the atmosphere at all wavelengths. Even if they did, they don't have the computing resources to process that kind of data, either. They can barely scrape together enough procesor time to carry out research on the data they DO collect.

You expressed this so concisely and simply - and I hope you continue to do so. People just don't get this message, and they urgently need to.
The argument that this is applicable is flawed. First of all, what is the source of the numbers. I hear the right claiming it all the time, yet never see hard evidence. Second, even if there are more trees, the replanting of new trees does not re-establish the same leaf surface area immediately. It is tree leaves that absorb CO2 from the air, and young trees have fewer and smaller leaves, and fewer branches. So young trees on a per capita basis are not as effective as older ones as carbon sinks from that standpoint. Third, we have to consider global quantities of trees, not just North America. In Latin America, far more acreage is clearcut daily than is being replanted in the US. Hence, the removal of carbon sinks by third-world countries is not balanced by any phony PR efforts by American logging companies. And finally, there are huge and increasing numbers of CO2-belching vehicles you're not counting. Talking about trees and lungs alone is misleading.
So 2 years of readings out of almost 50... that means that 1/25th, or 4% of all the measurements are these "high" values. If these numbers had shown up 10% of the time should there be panic? 5%? 4%?
Can you say insufficient data?
Today's message is brought to you by the numbers 2, 4, 50, and 100.
We need to start doing something to reverse the trend or the costs will be catastrophic. The causes don't matter and the facts are indisputable: the Earth is getting warmer and there is more CO2 in the air.
Using your logic, you could also say "the Earth is getting warmer and there are more humans on Earth than 100 years ago. Therefore, we should kill enough people to put our population numbers back to what they were." You've just arbitrarily chosen CO2 as the linchpin of your argument. You could have just as easily chosen a huge number of other variables, each of which may be just as important or even more important to the overall climate equation. But, hey, doing something is great, right? Sure, let's just make a decision based on incomplete, unsupported findings by a few scientists and disregard the equally-valid counterclaims of other scientists.
Your mentality in this is alarmingly uninformed, but common these days. It amounts to saying "we don't care what science says, we know what's going on and we're going to do something about it." Try being a bit more humble and you'll see the utter folly of your argument.
Let me tell you what would happen if everyone suddenly decided to think like you: everyone would focus on CO2 emissions to the exclusion of everything else. Research into possible other causes of global warming would wither and die. If you're wrong, you just made the situation much, much worse by jumping to an unsupportable conclusion.
There are three possible cases here: CO2 is reponsible for it all, CO2 is partially responsible, or CO2 has little or nothing to do with it. You're taking case #1 and calling everyone else liars. However, with better studies and more exacting information, we can emphatically say that CO2 is or is not the bogeyman we need to be pursuing. I'm not saying we wait forever, but a delay of a decade might give us much more valuable insight into a global climate we know very, very little about.
If history has shown us anything, it's shown that the more important the decision being made, the more reliable and voluminous the data must be before making that decision. Your thinking would shortcut that entire process. I again urge you to rethink your position on this and consider that science is far from being "done" with the entire question of climate change. This is not the Dark Ages of mysticism, so quit acting like you've got a crystal ball telling you the infallible truth.

I noticed on your homepage that more of it is in French than in English. This seems to fit with the annoying Canadian tendancy to intentionally misinterpret what "American" means.
Here's a tip for you: In English, if the context is unknown, "American" means a person from the nation with the Statue of Liberty and the stars and stripes on the flag. American is VERY VERY rarely used to refer to all peoples of North or South America. In fact, America unambiguously refers to the country, while the term for the 2 continents is "The Americas".
PS. Before you start to go off on that why don't you just say "United States" tangent, I'll answer it for you. There are two United States in the region: the United States of America, and the United States of Mexico. And we don't say, "people from the United States of America" because that's just way to long.
Lets presume you're right, then what? Do we proceed on some half-baked 'plan' to save the environment? What if whatever we do doesn't actually solve the problem - or worse, makes it worse?
The proper and necessary course of action is to actually come to a consensus as to what effect - if any - human output has on the environment, particularly with respect to 'global warming'.
Here is where the arrogance of so-called 'environmentalists' becomes staggering. To assume that humankind has any hope of significantly impacting a system as large and powerful as the earths atmosphere. Alas, arrogance trumps science, which is all too common these days.

Billions of tons, in gas form. Whoot.
Has any research been done regarding which plants are the best CO2 converters, and would increasing their numbers help at all?
Most people don't realize this.
Or, wait, did you think you were being ironic?
That would be funny!
Of F*CKING COURSE the planet is warming up! The planet is just trying to warm back up to it's natural state. AHHH!

While many agree that nobody is exactly sure what will happen with increased CO2 in the atmosphere, most models predict major problems. Should we wait until someone develops a perfect model, which might not be possible due to limited computing power, or do something about it now. If there's a 50% chance that widespread damage will occur due to global warming (i.e. rising oceans, more hurricanes/tornadoes, stronger weather, more drought, frozen Europe), then doesn't it make a lot of sense to try and limit the damage we cause?
Bush and others claim huge costs with complying with Kyoto. I don't buy it. Some companies (Du Pont, BP) are already complying and have found that they're saving money because they use less energy. Sure, hybrid vehicles cost a bit more to produce than regular vehicles, but I think the extra efficiency will more than make up for it over the life of the vehicle, especially with the rising cost of oil.
And using the fact that China doesn't have to comply is just an excuse. If the rest of the world follows Kyoto, it will help encourage China and those who don't to follow. Not only that, it will make the technology they need to comply cheaper.
I've seen a number of articles about other effects caused by the warming of the oceans. For example, while melting the polar ice cap won't in itself raise the oceans, it will raise the temperature further since ice reflects the sunlight back out into space whereas water absorbs it. A rise in the ocean temperature could cause massive amounts of methane to enter the atmosphere from all the methane hydrides at the ocean floor, and methane is a much bigger greenhouse gas than CO2.
Ignorance of the full global warming effects is no excuse for inaction when we have enough evidence that serious problems are likely.
Maybe we should also try and aid Indonesia with putting out their peat bog fires, which are releasing huge amounts of CO2 as a start.
As it is, today I was contemplating replacing my ancient inefficient refrigerator with a new efficient one. I think I'll go ahead and do it (it helps that Orchard Supply has a tax-free day today when sales tax is 8.75%).

How do the CO2 scrubbers in space vehicles work?
In SeaQuest 2032 or whatever, the earth's atmosphere was destroyed by global warming; there weren't enough rainforests to process CO2. So they build massive CO2 scrubbing refineries.
Would something like that be viable?
Please give the poor human population on this planet a sign that will let them know the world is much more complex, and better balanced than we could ever hope to understand. Show us, in some manner, that we as humans cannot destroy our world.

Since my Prius engine shuts off when it's not needed - like for instance when I'm sitting still in a traffic jam - I find the air immediately around my car is cleaner than around other people's cars.
If I let six feet or so open up between me and the fume-belching Hummer in front of me (target demographic for Humvees: same as for penis enlargement - it's true!) I can open the windows and enjoy a nice breeze...
Most of my family died, is dying, or expects to die from cancer. So the Prius is an investment in my own health, because it's part of a larger program of reducing my exposure to carcinogens.
"CO2 is not a greenhouse gas! My daddy said so."
Hmmmm... Difficulty in maintaining the satellites is the problem? Or perhaps its the weird and subjective fudge factors that are applied to the service record to compensate for heat islands?
Sorry, I trust the satellites. You should too.
As a show of solidarity, I'll start holding my breath first. Anyone else who feels so inclined, go right ahead.
Hey, just wondering if you could enighten me a little more of how, if in fact, the satellite not reading an increase in temperature is supportive to the global warming thesis? If I understand the greenhouse gas effects correctly, it is that more heat is retained, thus resulting in LESS radiant energy being detected from space... right? (I understand that there was no mention of detected radient temperature dropping along with the comment that it wasn't increasing. If it is otherwise, then I would like a url so I can also be infomed.) IF, (and a big if at that), there is no decrease in radient energy then this also goes against the global warming thesis, unless the sun decided to add a massive amount of extra energy to the earth all of a sudden. -- also, I would add that I am somewhat curious and amused at this entire argument. Instead of just telling us what is wrong, how about suggesting a cure? ...Or is there no such suggestion because it is too complex for us to actually know if we would be able to have an effect? Are we really this haughty as a race, or are we actually advanced far enough to presume to 'control' the global climate? -- just curious.
"Our Constitution was made only for a moral and religious people. It is wholly inadequate to govern any other" -John Ada
At least, too young to remember the drought and heat wave of 1980. It caused somewhere in the neighborhood of 10,000 deaths in the U.S. and billions of dollars of damage. The years around it were no picnic, either. I remember frying an egg on a cinderblock for brunch at my grandmother's house in eastern Oklahoma that summer. I have read accounts since then that say it can be done if the temperature is as low as 95 degrees, but we tried several other times and never got one to fry if the temperature was lower than 105 - maybe something to do with using a cinderblock instead of a sidewalk (there aren't many sidewalks in the country).
And you're a moron for believing it.
I just wanted to throw in my view for a second (thats what we do around here anyways). I bet there are people around here that might not mind having the environment get a little warmer. Who is to say that beachfront property in the middle of the US isn't desirable. Some people might like it a little cooler too. So if we all stop producing any CO2 and find new ways to make it colder, it would be nice to not have to run the AC all summer. The point I am trying to make is that argument can go either way. The people that are intelligent enough to look at the available information will do so. They will draw their own conclusions and they will use their system of ethics and morals to decide a personal course of action that may include lobbying for reform. The media is just like the annoying 13 year old that will say ANYTHING just so that he can get a rise out of you. Just kick him in the groin and get on with your day!

I there
Here's what we (or rather, I) know and don't know about this. We know that the Earth is trending warmer, empirically. We know that the amount of carbon dioxide in the atmosphere is increasing, and that CO2 is a greehouse gas. We don't know how significant the amounts involved are. You can make anything look impressive by plotting it ona graph with a small enough scale. What I want to know is how much CO2 we can dump in the atmosphere before the temperature goes up a degree. We don't know whether there's anything we can do about it, or whether it's already too late. We don't know how much warming may be due to non-greenhouse factors such as orbital fluctuations or whatever it is. We don't know what the cost/benefit structure looks like. If we're only going to lose New Orleans and Holland and everybody else is safe, and we'd have to go back to living in caves to prevent the climate change, then it's time to move those folks to high ground. I, for one, am open to persuasion on these issues, but I want solid answers (some of these may already be answered, but I'll admit to not having done the research). If the solution is "let's go back to living in caves now and see what happens," I'm out. If it's a matter of pursuing some reasonable alternative energy policies that we should be pursuing anyway to ease our dependence on foreign oil, I'm in. If it's Kyoto, which appears to have a huge cost for a relatively small reduction in human CO2 even in the unlikely event that everyone hits their targets, and which exempts huge stretches of the polluting world, I'm extremely sceptical. If all these answers are known, and the result is that we have to dismantle the industrial economy to survive on this planet, I'm still out. Once we do that, there's no going back and no long-term possibility of survival when the planet's resources are exhausted. Technology is our long-term hope, period. Time to move to Mars instead.
Or maybe you read it in the Spectator, or heard it on Limbaugh...
The scientist (note use of SINGULAR here) who came up with "the whole Global Warming research", as you put it, did not need to cherrypick data. His data was all accessible to the public when I personally verified it after listening to him speak around a decade ago.
God, you people are sheep. Baaaaah!!! BAAAAAAAAH!!!
just out of curiosity, has anyone done a serious study covering heat polution, as opposed to 'greenhouse gasses'? i mean -- having a couple of billion internal combustion engines, who knows how many power plants (using the old heat->steam->mechanical energy->electricity cycle), internal environmental controls (e.g. furnaces, air-conditioners, &c.) running, for which there is no serious analog, just 2 centuries ago, has got to be doing something to the environment. is all of this waste heat (e.g. not just del-H, but del-S) just radiating off into 'space'? how many BTUs of extra heat [beyond what we were generating back in - say - 1804] are we generating/liberating, these days, and where is it all going?
It's funny how certain so many people can be of something that we, as a species, know so little about. For those of you who are so certain that humans are the sole culprit of the atmosperic changes, I want you to consider a couple things. Being that we have been studying this phenomenon for what is a geological blink of the eye, how can you be so certain this isn't part of a cycle that we are still discovering. Explain how we have come out of the previous 9 or so ice ages without SUV's, factories, and excessive bovine farts?
This raises the ugly possibility that the capacity of a large carbon sink (possibly the oceans) has been exceeded, and the worst-case scenario is that a tipping point has been reached and a runaway warming scenario is in progress.
Oh, shit!!! Time to buy land in north Canada.
The permafrost apparently contains a HUGE amount of trapped methane that is being released as it melts. This new finding will have to be studied and added to the global warming models.

Keep in mind that methane is a much worse greenhouse gas than CO2 -- 25 times worse!

The CO2 levels increased more in the last 2 years than they did from 1958 to 1999 !
Grow up americans, take some responsibility for your actions and stop denying any wrong-doing.
Meh.
This is very insightful. I had known about these potential super-tsunami landslide sites, but never thought about the terrorist connection.
What is interesting is that this is old news, about average CO2 during 2002 and 2003. The record high 2003 increase was reported already at the beginning of the year, and then there were news about record-high March announced by someone with access to the information in a conference.
Does anybody know the origin of the current news story? Was there a press release somewhere? Why just now? Because of the US election or because the trend has got more confirmation during the recent months?
(Yes, models are uncertain. No, warming is most likely not due to natural causes. CO2 increase is definitely mostly of human origin. Biosphere is very complex. We have played Russian roulette enough for now.)
Why not quote from the Weekly World Standard? Or the National Enquirer?
Both papers have the same level of journalist standards.
The balance of evidence suggests that the world is indeed warming up, but climatologists do consider the microwave sounding data to be a real anomaly that they can't easily explain away.
The Intergovernmental Panel on Climate Change also says, in their report Climate Change 2001: The Scientific Basis that "It is very likely that these significant differences in trends between the surface and lower troposphere are real and not solely an artifact of measurement bias," (p. 102)and that "uncertainties due to limited temporal sampling prevent confident extrapolation of these trends to other or longer time periods. ... [A] full explanation of the lower-troposphere lapse rate changes since 1958 requires further research." (p. 123)
See, for instance, Global Warming Trend of Mean Tropospheric Temperature Observed by Satellites, by K.Y. Vinnikov and N.C. Grody, Science 302, 269-72 (2003), which points to the difficulty of maintaining calibration of the microwave radiometers through the diurnal cycle and the problems of determining appropriate weighting functions to calibrate measurements taken with the radiometer pointing somewhere other nadir.

Think about it...when did temperatures start to rise...right about the time that countries, all around the world, started to implement daylight savings!
You introduce an extra hour of sunlight...every day...for a third and sometimes half the year...and wonder why it starts to get hotter!!! Crazy. It's just common sense!!
Stop daylight savings and you'll have an hour less of sunlight during the day...it's bound to cool back down then.
I have told my theory to many leading atmospheric scientists but they, or rather the officer issueing the restraining order, were unwilling to enter into debate about the subject. I think there may be a massive coverup underway by the leisure craft industry.
Bravo! You just gave a brilliant example of why democracy sucks!
Laws are horrible moral guides, moral guides make even worse laws.
I understand that China is keenly interested in HYBRID vehicles being given entry priority.
I have harped away off and on over the past 2 or so years, as if I have a Chinese Officials audience, with, essentially, these points for China:
China, PLEASE, PLEASE, for your domestic consumption, national security, and local and global pollution concerns:
--don't let in ANY foreign vehicles which don't offer hybrid or Honda ULEV (ultra low emission vehicle) standards
--don't let your nation have hundreds of thousands or millions of new drivers monthly taking to the roads in pollution-belching, smog-assisting vehicles. If Ford, Chevy, Dodge, Chrysler, GM, and the rest of them drag ass/drag feet and don't want to DO what they technically CAN and KNOW how to do, then to heck with them. Honda and Toyota can give you what you and the world needs: Cleaner vehicles
--DON'T let your nation become more addicted to oil for all those new vehicles coming ashore. If you do, you could find yourself in the position of being AT THE MERCY of the US, should the US decided to grab the oil fields you and Japan and the rest of Asia need to remain opened and unfettered. If you face being starved by the US, it could force your hand and make you precipitate a war, war which no on needs
--Lighter vehicles, particulary the non-allowance of SUVs, would allow your roads to last longer, requiring lest tar, asphalt, cement and other materials which also exude chemicals under harsh sunlight, and material which is worn off and sent into drains or into the air
I rattled on with more details, but these are the salient points. Besides, if more cars are produced locally there, and are cleaner, less maritime/marine fuel would be used shipping all over the place.
So, to me, it seems China WANTS to publicly, if not actually, do a nice part. We'll see, though, in a few years, based on satellite imagery.
The time is NOW for automakers to get off their oil-shackled asses and start mass-producing hybrids and lower-horsepower vehicles so that economies of scale will forever shut down the squealing, lying-assed manufacturers garbage about "we're losing money on hybrids".
First of all, they're outright lying to maintain their comfort zone.
Second, they're being manipulated from within and without to dupe the public into not pressuring them as much.
Third, NO, I repeat NO average citizen joe or jane deserves or has any RIGHT to drive a recklessly irresponsible, gas-swilling vehicle high-horsepower. Why should civilian vehicles (other than the weak argument of allowing citizenry to "blow off steam on occasion) have over 150 horsepower? WHY? Just to pass up somebody? Show off some status? Evade or speed away from a stalker? BS excuses, and poor, weak states of mind, I think.
Horsepower, necessitated by heavier, show-off vehicles, and coupled with mindless demand for ever-increasing "POWER and SPEED" contribute to the production of major gulpers of fuel.
The ONLY I repeat ONLY entities entitled to drive powerful vehicles should be:
-law enforcement
-heavy construction
-product transportation
-mass transit
-fire, medical, and rescue teams
-agriculture
-SOME, but not all, individuals who demonstrate a need to be securely transported from point A to B
and similar.
Individuals who THINK they need a gas-swilling vehicle need to rethink their options, and change their habits. If they think this piece of my mind is an encroachment upon "their rights" then maybe THEY should play chicken in the road to earthmovers that can crush them; maybe THEY should be put into rooms hooked to CO2 and other exhaust by products; maybe THEY should have a greatly higher property tax or use tax on road-wearing, air-heating, intimidation-exuding vehicles.
I don't expect "perfection", but dammit, the progress towards cleaner combustion or pure electric with reduced horsepower needs to be sped up.

First of all Lomborg is not an authority. He has a PHD in political science. The fact that you would hold him up as an authority in the study of climate change shows exactly how ignorant you are.
Secondly you want people to take your word over the scientists that actually study this. Tell me one reason why I should believe you instead of the scientists.

Regardless of potential difficulties involved in satellite temperature readings, I'll take an unbiased satellite reading that is calculated by a computer to a collection of hundreds or thousands of individual station readings that are manually massaged by what can only be called a "fudge factor" to compensate for local urban heat island effects.
You suggest that we completely understand the atmosphere and the things that drive it. We don't.
Here is the issue we have with it. At least 3 times in the last 2000 years the sun has, for its own mysterious reasons, stopped producing sunspots. These are called the Wolff and the Sporrer and the Maunder minimums. (Excuse my spelling) These sunspot minima are correlated with signifcant atmospheric change. The last one, and by far the best observed, the Maunder Minimum, happened the same time as the Little Ice Age. Periods of high solar activity correlate well with increases in terrestrial temperature, eg. the Dust Bowl Days.
Right now, we are entering a period of exceptional solar activity. [I am of course talking about years at a time, because at the moment, we have just started into the declining phase of the solar cycle.] And likewise, we notice the Earth getting a bit warmer. This happened in the Middle Ages too.
The only real objection, is that we have no idea, how this is happening. It doesn't appear to be Total Solar Irradiance, but we have not had high quality observations for that long. More likely, it has to do with the sun's extended magnetic field, and whether we are impacted by slow or fast solar wind, or both. That does have an effect on the upper atmosphere.
I admit, this is not an objection to be ignored, but nor is the very good correlation between global temperatures and solar activity.
Stop acting like anyone who disagrees is a crackpot or a terrorist. That is devisive and short-sighted.

So at 30 billion tonnes per year into an atmosphere of 1800 billion tonnes... that's a 16% man-made increase in atmospheric CO2 over 1 decade, except this sort of thing has been going on in various amounts since the industrial revolution.
C yc le/carbon_cycle4.html
Sure CO2 levels are naturally cyclic, sure we might just happen to be on a peak, but current atmospheric carbon dioxide levels are above 370 parts per million, that's higher than any level ever recorded from an ice core, ~30% higher than any peak the natural cycle has ever produced, and over 150000 years it just co-incidently happens to be occurring while we spit out 30 billion tonnes of it a year.

Russia wants to join Kyoto because the very essense of the Kyoto Treaty creates a "pollution credit" as a form of tradable currency. Credits were calculated based on 1990 production output. Russia has since entered an industrial decline, and thus under the Kyoto calculations would have a incredible excess of "allowed pollution" amounts. Under the treaty, they could trade away these credits for cold hard cash, possibly as high as $3 billion a year income stream...
China loves Kyoto because they managed to get themselves exempted from it under some "third world status" clause, despite the fact that they have since grown to become the world's second largest consumer of petroleum resources.
So in this case, the U.S.'s policy of doing nothing is, in fact, the best political action for them to take. "Yeah, I want to sign myself into an agreement that will cost my country billions in retrofitting factories, while exempting my philosophical rival nations from any responsibility. Oh yeah, and we're going to allow them to compete commercially with us on the open markets, such that their goods will always be the lower cost (since they don't have to follow the environmental regulations) which will only hurt my future gross domestic product." Brilliant!
Hey lets face it, if Global warming were WMDs there is more than enough evidence to go to war.....
This is a real problem, but people have been working hard on it for 15 to 20 years. Just last week, a paper was published in Science Express (the advance version of Science) that suggests that the uncertainties in measuring past climates are greater than what are commonly accepted by mainstream scientists. The article is available only by subscription, but the New York Times has a good balanced account of it.
http://www.physorg.com/news1041.html
I'll also agree that we need more data. We need to know what's happening, why it's happening, and what effect it has on the biosphere, both short-term and long-term.
The only thing I'll add is that we need that data as soon as possible. If the sun is a larger factor than environmentalists have considered, we need to know now for economic reasons. If the sun is actually a smaller factor, then the models need to be scaled up accordingly.
Whichever way it is (or even if the current models have the sun's influence dead-on) we need to know BEFORE we go down a catastrophic path, and we won't know how long we have before we go down such a path until we have the data.

We have over 400,000 years of useful atmospheric data. Your ignorance of this very basic fact disqualifies the entirety of your statement.
I grew up in the 1950's, in Virginia. The air was fresh, Monarch butterflys visited our "butterfly bushes" every summer as they migrated south. They were so very beautiful. Over the last year I have been blessed to figure out why the LN2000 nitrogen engine failed to work properly. I share your sentiment there bigberk. I don't want to have the noose of History around my neck for being the generation that killed Mankind. In the U.S. last I heard we spent $15 trillion last year for medical care, and much of our worst medical needs stems directly from air pollution. I recently completed several pages describing as best I could how a "steam-enhanced" nitrogen engine can be totally non-polluting. I also wrote 5 pages I called "Icy Hot". All of these links are reached through http://www.newpath4.com/NNINDEX/nnindex.htm and http://www.newpath4.com/effectsofairpollution.htm. The original LN2000 pre-warmed the nitrogen, expanded it to where it didn't have much power left, because the inventors were trying to keep the supercold liquid nitrogen from freezing the engine piston to a crawl or a dead stop. Sucked the power right out. By adding steam before the nitrogen, I showed how to get the FULL EXPANSION & UNLEASHED BLAST OF POWER inside the engine cylinder. By using two inert mediums as donkeys to carry energies into the cylinder, all of the power -an explosion without combustion- occurs where it's needed. Soon we'll be able to drive to our heart's content and not pollute this planet. We can drive SUV's and stretch limos if we have the money. [And why shouldn't we once we're using a free fuel supply?] Also, I'd like to make a note, that by using these cold & hot energies, the engine is TEMPERATURE-BALANCED and does not need a COOLING SYSTEM. Which means we can do away with poisonous antifreeze for all our cars that has been adding to the planet's overall pollution and groundwater soilage, not to mention leachate from our dumps. I released the engine for free onto the Internet to counter what you're saying, how the corporate moguls seem to be dropping the ball for profits. If Detroit refuses to build it, I'm sure the Japanese will be there for us. Oh yeah; it doesn't need a heavy starter or battery either...

I normally don't comment on slashdot articles, but this time the topic is in my area of science, as i am a Masters Geology at a New Zealand university and i have substantial spatial modelling experience.
m /co2.html
:-)
Firstly, my comments based on my geology background. Taking CO2 measurements from the peak of a large active volcano and using it for broad scare-mongering stories on a potential approaching cataclysm is, well, stupid. The only legitimate use for such data is to form theories on relationships between CO2 emissions and basaltic volcanos and the Hawaii Volcanic Centre, and build some predictive models of C02 emissions and future volcanism. At the most you could claim you are investigating volcanic contributions to worldwide C02 concentrations.
See here for basic data on Mauna Loa:
http://hvo.wr.usgs.gov/maunaloa/
See here for a study on C02 emissions from Mt Erebus, the most active Antartic volcano:
http://www.ees.nmt.edu/Geop/mevo/geoche
Secondly, my comments from a spatial modelling perspective. Pre-satellite data collected in the past on C02 concentrations and temperature in the atmosphere (from balloons etc) and nearer the Earths surface (ground stations etc) are taken from discrete sampling locations, often at discrete points in time, often located near major urban areas. This leaves CO2 and global temperature models based on this data inherently biased due to:
1. the assumed spatial relationship between two or more points of data, ie a bogus belief by some
modellers that you can simply interpolate data over regions of land or volumes of atmosphere between two or more real world locations.
2. the assumption that a measurement taken at one point in time is representative of all values possible over a certain time frame, e.g. taking a measurement at midday on one day of the year as being representative of all times in that day, week, month, season, year etc.
3. the inevitable complication of rising urban temperatures, not just purely in terms of temperature rises, but dramatic changes in the distribution of temperatures throughout a given day. This is largely caused by the thermal properties of concrete and other building materials. Search the Internet for "Urban Heat Island Effect" or similar. I imagine similar problems arise with C02 measurements taken near urban areas and airports, but this is not likely a problem near Hawaii.
And another point: do not trust the Guardian, or the Independent, or New Scientist or any other popular media publication, for accurate scientific sumnations. If journalists knew a damn thing about science they would be getting far better pay actually doing scientific research, rather than working for partisan media publications.
Try "Science" or "Nature" instead.

Why doesn't it work? Well, there's always the difficulty of choosing the True Religion. Then there's always the difficulty of getting people to give more than lip service to any part of it other than their own favorite hobby doctrines.
And there's the issue that God, if God exists, seems to be quite content to let the average joker screw him/herself until reality hits.
So the real problem seems to be lack of patience. The problem will be solved one way or another.
In the meantime, I want to see something that can be done without making things worse:
Passive solar water heating seems to be good.
Windmills seem to be good, but I'm wondering about the hidden production costs. I'm not too worried about the effects on wind patterns, but I think there should be some simulations run. (Do we have the technology?)
Bicycles seem to be good.
Jobs close to home seem to be good, but there seem to be socio-political-advertising problems with those.
Telecommuting ought to be good, if we could get the semiconductor industry to slow down their pollution now that we have what should be enough power in the average desktop to support it.
Farming our own land seems like a great solution to the global warming, if only everyone would do it. Of course, some people think there are too many disadvantages to that, worried, I suppose, about the carbon dioxide, natural gas, and heat produced by septic tanks, composts pits, and cattle.
What is amusing about the articles title is that any variation in CO2 is unexplained. The existing models do not explain any of the CO2 levels, including methane, water vapor, etc. The assumption is that CO2 increases (including methane) are caused by humans. However, when levels decrease humans are not given the credit. This is a standard example of circular logic. Lorenz
Now, if you meant "levels are higher now than they would have been without our presence", then you might be "more" correct, but even then there is the possibility that humans putting out CO2 could in fact cause some sort of negative feedback effect where the "final" levels of CO2 wouldn't in fact be lower than they would otherwise have been. The point is: Without much more solid evidence of causation (correlation isn't even close to good enough if you want to "prove" a positive) there is no way to know, and using such faulty logic is dangerous and counterproductive. (You know you really have to watch out when words like 'obviously', 'clearly' and 'of course' are being thrown around.
It's not that I don't tend to intuitively agree with you that it seems likely that we are affecting CO2 levels (although I am far from certain that it's any more than a 'blip' in the grand scheme of things) -- I just don't know of any proof and admit as much.
I won't respond to the rest of your post which is basically alarmist rhetoric based on the false assumption that the mere potential for grave consequences of something we don't even know is happening requires us to Act Now.
HAND.
Let's get definitions straight: theory means "a well-substantiated explanation of some aspect of the natural world; an organized system of accepted knowledge that applies in a variety of circumstances to explain a specific set of phenomena; 'theories can incorporate facts and laws and tested hypotheses.'"
And forgive me if I don't trust the people that have been massaging the data for 15 or 20 years since many of them depend on ongoing funding that would be in jeapordy if they were to massage the data a little more conservatively. Just like some people don't trust global warming skeptic scientists as pawns of some industry, I don't trust pro-global warming scientists when their potential source of investigative funding is at stake.
Rather than trying to fudge an inherently inaccurate and incomplete surface record, these scientists should focus on resolving any problems they have with the satellite record which is the only truly global temperature record we have. After all this is supposedly global warming. You're being naive if you think we're going to be able to adequately monitor it by some strategically placed thermometers in heat islands of urban sprawl and generally ignore the 75% of the earth's surface that is covered by water.
I would also point out that even Lindzen agrees, in the document cited above and in his testimony to the US Senate, that "global mean temperature is about 0.5 degrees Celsius higher than it was a century ago," but he claims that we can't tell whether this temperature rise has anything to do with the rise in CO2 levels.
I also find it strange that you would assert that over the past 20 years the Reagan, Bush 41, and Bush 43 governments would have cut funding for scientists who found that the world was not warming up ("many of them depend on ongoing funding that would be in jeapordy if they were to massage the data a little more conservatively"). I can see this charge against the Clinton/Gore administration, but for most of the last 20 years we've had conservative Republican administrations. Can you substantiate this claim?

The problem is that to distinguish anthropogenic warming from natural climate cycles, you need a very long climate record. We don't have satellite records from 100, 1000, or 10,000 years ago, so even if satellites unambiguously said that the world had warmed up significantly in the last 20 years, this information would not tell us whether the warming was part of a trend that correlates with CO2 concentrations or merely a coincidence.
For this reason, we use both instrumental records (which do suffer from the urban heat island effect you discuss) as well as indirect records (dendrochronology, hydrogen isotope ratios from ice cores, etc.).

The 75% of the earth's surface covered by water is measured, albeit incompletely, by water samples drawn by ships crossing the oceans. We have a few hundred years of data from this, but just as with urban heat islands, there are problems comparing old data with new (e.g., evaporative cooling of water sampled in canvas buckets on old sailing ships vs. measurements at subsurface water intakes on modern vessels).

.I could try to engage you on the issues, but, it seems to me that you're either a shill for the petrochemical industry (the bit about a "catastrophic solution" was a nice touch), terminally dumb, or a plain old troll. So any way you cut it, saying anything more would be a bit of a waste of time.We have 500,000,000 years of data from ice cores that indicate co2 levels have either no or the opposite effect on global temperatures. This data carries more weight then the short term data collected today that is based on the assumption that co2 increases global temperatures. It is assumed by many that because of the correlation between increasing levels of co2 and global temperatures that there is causation. There are many different mechanisms at work and which ones are at work in our atmosphere are difficult to determine over the short term. Thousands of years of data are required to make accurate predictions about global climate changes over the long term. Please keep in mind that greed and power can also be involved in the need to scare people into rash action. The following is a non-profit organization that puts data out that shows there is a legitimate other side.

"If you would be a real seeker after truth, it is necessary that at least once in your life you doubt,as far as possible
But did they actually read any of the material cited in the bibliography? And, more importantly, did the politicians who made policy recommendations read the bibliographic material or even the the full IPCC report?
I doubt it. And I can understand that. Most politicians don't have time to read hundreds of pages of dry climate information. They read the summaries and while it's been awhile since I've engaged in this discussion (and as a result I don't have links ready and I don't have time right now to dig them all up again) it has been my observation in the past that even the full report doesn't give adequate time to the reservations. They talk about the results of climate models and, last time I checked, essentially devote a single sentence that effectively says that the climate models aren't necessarily accurate and are "always improving." Considering the more the climate models improve the lower the global warming predictions become, basing policy decisions on these models is premature. And the IPCC full report addressing this absolutely paramount concern with a single sentence tells me just how much science there is to be found in the IPCC full report and how much politics.
If you can find otherwise please let me know. I'd be glad to be proven wrong. But in the past I did read a large portion of the full report and specifically scanned for comments on the accuracy of the models and was dismayed at how that whole topic was pretty much ignored.
I also find it strange that you would assert that over the past 20 years the Reagan, Bush 41, and Bush 43 governments would have cut funding for scientists who found that the world was not warming up ("many of them depend on ongoing funding that would be in jeapordy if they were to massage the data a little more conservatively"). I can see this charge against the Clinton/Gore administration, but for most of the last 20 years we've had conservative Republican administrations. Can you substantiate this claim?
It's not that the government would cut funding for those that find that the world is not warming up. It's simply that the much academic research is government-funded and funds tend to not be forthcoming when you say nothing is happening. If a scientist says "We did this investigation and found that human-induced global warming is not happening" then he's not going to get any more funding. Not for any political reason but simply because if they've already said the global warming isn't happening, why give them more money to investigate global warming? Ongoing funds are insured by investigating the theory and either reaching alarming conclusions or leaving the investigation inconclusive to warrant more research.
It's like the idea of building a light-bulb that lasts forever. Not a good financial idea for the light-bulb makers because they'll make one sale and then they're done. Likewise scientists that conclude that human-induced global warming is not happening are eliminating their possibility of getting more global warming research funds in the future.
Logiacl conclusion: We have insufficient data to make a rational recommendation. I don't subscribe to the belief that "Even if we're wrong about global warming, drastic cuts in CO2 production is the right thing to do anyway." The impact on humans of significant reduction in CO2 could be as drastic as the worst fears of global warming. We should not embark on major policy changes based on insufficient data.
For this reason, we use both instrumental records (which do suffer from the urban heat island effect you discuss) as well as indirect records (dendrochronology, hydrogen isotope ratios from ice cores, etc.).
My understanding is that the information taken from ice cores, etc. is significantly less alarming then what we would be made to believe from the instrumental record. And I believe that the effects of heat islands, etc. on the instrumental record are so severe and the impacts are impossible to know with certainty that the data should be pretty much thrown out. Certainly not used as a basis for recommending draconian CO2 reductions and rationing.
So we have a satellite record that is too short to be helpful and an instrument record that is too inaccurate to be helpful. We don't have enough information.
The 75% of the earth's surface covered by water is measured, albeit incompletely, by water samples drawn by ships crossing the oceans. We have a few hundred years of data from this, but just as with urban heat islands, there are problems comparing old data with new (e.g., evaporative cooling of water sampled in canvas buckets on old sailing ships vs. measurements at subsurface water intakes on modern vessels).
Of course we have samples from ships at see but they are incomplete and generally only cover the major shipping lanes. If you're lucky instead of missing 75% of the planet covered by water we're only missing 74%.
I feel hugely compelled to point out that the Neo-Con smack for brains have failed to launch a pre-emptive strike against Global Warming...

The 2001 report also has detailed discussion of model uncertainties. Chapter 8 is all about model evaluation and concludes with a section on what is and is not reliable about the models on a scale ranging from "well-established" to "speculative."
There are numerous graphs showing model calculations versus observed climatic data (see, for instance, figs. 8.15 and 8.19).
The authors of the scientific sections of the IPCC report are indeed real practicing scientists, many of them the best in the field, and they do seem to have read the literature quite comprehensively.
On self interest and scientists, it's amusing that you accuse them of exaggerating their certainty about global warming to keep the funds coming. A couple of years ago, Roger Pielke, Jr., and Daniel Sarewitz accused climate scientists of exaggerating their uncertainty about global warming on the grounds that if everyone accepted that warming was a real threat, politicians might divert funding away from research and toward action. Thus, Pielke and Sarewitz accuse climate scientists of accepting research funding as bribes for continuing to say that things are uncertain and further research is needed. P & S argue that honest climate scientists would say that we know all we need to know; further research is unlikely to resolve uncertainties in any useful way, so we should hang up the expensive research and start taking political action.
I don't buy either your idea that scientists are exaggerating fears of climate change to keep funding coming or Pielke and Sarewitz's idea that they are playing up the uncertainty to keep funding coming. I think they are being honest and recognize that even if they stopped doing climate change research there would still be a lot of well-funded opportunities at predicting ENSO events, droughts, tropical storm trends, etc. It's not as though natural climatic variability is economically or politically negligible.
Sadly we have presumed in many cases that CO2 concentration in the atmosphere, and global warming as a whole is a linear process. As we are now seeing, and could have easily predicted if we hadn't been desperately trying to justify our American SUVs or Chinese fossil fuel powered industrialization.
Permafrost represents nearly a third of the vegetative surface of the earth. It has locked up in it, as much or more CO2 than currently present in the atmosphere. At it's melting fast. All through northern latitudes the phenomenon of "Drunken Forests" is becoming all too common. These are forests rooted in permafrost, that is now suddenly melting and the trees are slowly falling down (the ones standing do so at drunken angles.)
Another potential horror, is the real possibility that changes in the temperature and salinity of water in the Atlantic, could cause it to suddenly and without warning belch up a catastrophic cloud of CO2. If this were to happen close to a populated shore, the results could be the death of tens even hundreds of thousands of people.
Huge CO2 sinks suddenly releasing their stored gases could amplify global warming (and associated feedbacks.) The results are still very hard to predict, but the best likelihood is that higher life on the planet would have a very bad time of it. We need to begin addressing this problem now, or it will address us in a extreme and permanent manner soon.

I heard that NPR program too. The attempt to be fair was a bit underwhelming, and may have been deliberately sarcastic. Here's why:
:-(
First they interviewed a scientist, giving the standard scientific view. Then they said, "but some scientists disagree..." and proceded to interview a LAWYER [?!] glibly saying he knew lotsa scientists who thought [insert environmental catastrophe here] wasn't a problem.
They certainly could have done better by not playing along with the lawyer's pretense that his scientists existed. But to let a lawyer pretend to speak for a rumored scientific community--that was pretty facetious of them! Too bad the joke is probably lost on most of the public.
Similarly, we are facing decisions today about the environment where any reasonable scientist will say that we can't be very certain about the consequences of our choices.
If we put off reducing CO2 emissions and global warming turns out to be on the bad side of the range of estimates, we may be faced with thousands of years of environmental disaster.
On the other hand, if we prematurely cut CO2 emissions and global warming turns out to be on the benign side of the range of estimates, we will have condemned billions in the developing world to unnecessary poverty and disease that could have been helped with the money earned by faster industrialization.
For about ten years, I have taken the position that the focus on the climate record of the last century has received too much attention. If we step back from the details of the short-term temperature record and ask about long term climate futures, I see a different picture: Right now, we can be quite certain that the amount of carbon dioxide in the atmosphere is more than 20% higher than it's been at any point in the previous 400,000 years and almost all of the increase in the last 15,000 years has occurred in the last 50 years, exactly as we would expect if the increase was solely due to burning fossil fuels. With less certainty, it appears that CO2 concentrations may be about 20% greater than they've been at any time in the past 22 million years.
While reentrant feedback loops in the climate make it difficult to sort chickens from eggs and conclusively demonstrate causality, there is a clear correlation between CO2 levels and temperature over the past half-million years. The physical basis for a causal connection between CO2 concentrations and temperature is well-understood, although it's legitimate when critics point out that feedback effects can be large enough to completely overwhelm the primary forcing.
It's also true that our uncertainties about aerosol forcings are larger than the total effect of anthropogenic CO2 emissions to date (IPCC discusses this and clearly states the uncertainties). This means that we do not understand climate well enough to state with certainty what has caused the climate changes that have been observed in the last century. The balance of the evidence suggests to most scientists that CO2 emissions are responsible, but there is certainly room for reasonable people to disagree, and they do!
Where I come down with this uncertainty is as follows: Over the past 100 years, we have increased the amount of CO2 in the air by about 25%. If we continue the current trends of CO2 emissions for another 100 years, atmospheric CO2 at the end of this century will be several times its preindustrial value.
We don't have any reasonable climatological data from the past to tell us what the earth would be like with four times its current CO2 concentrations. There is good reason to worry that there could be severe climate disruptions. If there were, it would take thousands or years or more to bring CO2 levels down to their preindustrial values, so we would be stuck with a changed climate for a long time, even if we assume that there is no hysteresis in the climate system (events such as the Younger Dryas suggest, but do not prove, that there may well be hysteresis that would make it even harder to reverse the climate change).
If we are wrong and slow down industrial activity for several decades and then find out that
Thats all you've got? I'm sorry to say that none of those were ever inconceivable to men of learning and intellect.
The notion that man, whose collective energy output is 114 gigajoules (114 x 10^9) could ever significantly impact a system which contains 131 terrajoules (131.0 x 10^12 joules) of energy, is quite frankly ignorant. If the global climate were really so fragile that a thousandths of a percent of fluctuation would destabilize it, then we would have been wiped out by solar flares eons ago.
Knee jerk reactions to unsubstantiated problems are probably more dangerous than the problems the are intended to solve.
