Consensus on Global Warming
FredFnord writes "Well, here's an interesting one: the fine folks at Science Magazine have done an analysis of the last ten years' published scientific articles (articles from crank or non-peer-reviewed publications were not counted) on the subject of global climate change. The results themselves are interesting, but the most remarkable part was that, of the 928 papers they found, 75% accepted that global warming was caused by human activities, either explicitly or implicitly. 25% made no mention either way. And not a single paper asserted otherwise." JamesBell submits this article by a geologist which suggests that the Earth is in serious, imminent, unavoidable danger.

Soon, it will be China and India that you're pointing fingers at, and not the US (or Europe).[1]
So... Then what?
And uh, is this news? Does anyone credible seriously disagree that emissions from human activity are at least in part contributing factors? Or is this another jab at boogiemen that don't exist? There's nothing "remarkable" about these so-called findings.
Also, the "Earth" isn't in danger. Yes, I know this distinction is splitting hairs, but what's in danger is Earth's inhabitants. Our actions are not going to alter a several billion year old rock.
[1] Don't feed me the per capita shit. China will be a far, far greater polluter in this realm, per capita or no. Further, the economic empowerment of the Chinese people will eventually drive them to a level of concern about the well-being of the environment, so, in a way, their accelerated economic development is a good thing, politically and environmentally. Incidentally, China has proven they can reduce greenhouse emissions, even while growing economically (1, 2)...but the point is, they're still on an upward trend. And they've got a lot more people who will begin to thirst for energy-hungry luxuries.

Scientists have suspected in recent years that Mars might be undergoing some sort of global warming. New data points to the possibility it is emerging from an ice age.

Regardless, the final paragraph of the article begs a very interesting question:The begged question is Will it be bad or will it be good? Wouldn't warmer climates provide more arable land? What I get out of this is "We dont know what it means, but it looks like at least SOME climate changes are caused by man".
Global warming will cause the earth to explode? Oh wait, you mean people (and possibly much of the life on earth) could be in danger. I doubt global warming will make much of a difference to the planet itself, except possibly to allow it to make more room for heat resistant lifeforms :-)
I Am My Own Worst Enemy
From the article:
The American Meteorological Society (6), the American Geophysical Union (7), and the American Association for the Advancement of Science (AAAS) all have issued statements in recent years concluding that the evidence for human modification of climate is compelling (8).The American Meteorological Society and the American Geophysica Union? What a bunch of communists. They are just trying to destroy our way of life. They don't want me to live my life the way I want. Now, where did I park my Ford Explorer? I gotta run and buy a pack of smokes...

I think the reason this is news is because the Bush administration is still trying to pretend that this is not proven science... that it's just a theory that can be ignored. They want to ignore it because it's inconvenient for their business cronies, and those business cronies fund party activities and candidates' re-elections. I don't think there will be any changes on this front until this administration is out of office, no matter how much evidence is presented. It's quite unfortunate.

The Global Warming issue reminds me of big Tobacco. Deny , Deny , Deny. Years from now their will be no doubt that our habbits accelerated Global warming.
And the US supports the principles of Kyoto, but does NOT support the exemption of countries termed "developing", like China.
I'll be dead by the time any of this happens. What incentive is there for me to really care? Honestly? I know it's a problem, but how do you get people to care about it, when 1. They'll be dead by the time this happens and 2. There are more pressing concerns to deal with (bills, life, etc.)?
I don't respond to AC's.
Despite all the hoopla, the USA is not the greatest danger to the environment. We Americans are making steady progress. Note that Honda is technically an American automobile company since Honda does more than 50% of its manufacturing in the USA.
The greatest threat to the environment is China. The Chinese have been overwhelmingly burning coal. Coal horribly pollutes the environment and unloads tons of radioactive material into the air.
Given the current rate of pollution in China, once it reaches Singapore's level of economic development, the level of pollution in China will exceed that in the USA. India is equally horrible.
How many were rejected from the peer review process which suggested or concluded otherwise? More to the point (and obviously, this cannot be known) how many were never submitted for peer review in the first place because of concern over the backlash?
Most US science funding in climate and solar research comes from the federal govt (in geological and oceanic research sizable amounts can come from private groups). When politicians don't want to look like they're anti-environment they screen funding to make sure it's not going to go to "enemies of the planet" (I kid you not, that's the phrase).
How can a survey of peer reviewed journals be a valid source of data when people are afraid to publish "the wrong results"?
Perhaps global warming is caused by adult white male toenail clippings, but I'm pretty sure we have no reasonable way of finding that out right now.

Oh right, those don't count because refuting environmental destruction claims isn't politically correct! Look, I don't agree with much of what Bjorn says, but the point is he compiled some statistics, came to some conclusions, and was then ostracized by the political machine for being "irresponsible" for advocating what a very liberal Euro nation dubbed "wreckless science". The critique of his science (that wasn't much of that) was second to the smear campaign leveled against him for being irresponsible. His work didn't "count" I guess in however cooked up his stupid statistic also.
This is the same thing John Stewart was talking about during his CNN Crossfire talk, we're so right or left now we can't have an honest debate about real issues, which we really need. No papers are published because its career death because a very liberal academia has decided anyone going against this trend is scum, without even looking at the science. Nature would not accept a paper from someone that claimed otherwise, but this is a debate we really need to have folks.

Now, there's a solution I can get behind (no, I'm not joking). Nuclear energy, pursued with a strong eye towards safety and security, would be a step forward in terms of our efficiency and use of energy.

global cooling again. in the 70's they thought the world would freeze over, someone make up their mind
I basically agree with you on this, the evidence isn't air tight. However, that doesn't change the fact that we're still dumping tons of poisonous gas into our atmosphere every day. If nothing else, we should cut back on that.
When you get to hell -- tell 'em Itchy sent ya!
I love how lately on Slashdot anything a particular individual doesn't agree with has become "groupthink". As though that somehow makes it invalid. Has it occurred to you that maybe the consensus has been reached because global warming is a real problem, and that the evidience is overwhelmingly in support of humanity being a major factor?
At the risk of being labeled a troll. There are only a few ways that can convincingly prove a scientific theory: 1) carefully done experiments where all the extra parameters are kept constant, which is impossible in this case, or 2) either analytical derivation or computational simulation from "first principles" (also can't be achieved despite all the progress in HPC).
Studies that I'm aware of either show that there is a historical correlation between CO2 levels and temperature (no control for other sources that change climate) or ad-hoc models that are made to fit past data and then used to extrapolate into the future (approach has been tried before for stock market prediction without much success).
It's just very hard to prove human influence on climate.
Having said this, I think it's a very good idea to try find a better source of energy than oil and gas.
Because back then, these big-ass creatures called 'dinosaurs' roamed the earth, and when they went swimming, it caused the sea level to rise.
Simple, really.
Oh yeah, plus sponges hadn't yet been invented.
The Bush Administration rejects the Kyoto protocols, whether for good reasons or not, and then refuses to do anything else about global warming.
Bullshit.
14 Nations to Participate in Plan to Reduce Methane
This is largely driven by the US and it includes India and China. It'll have the same greenhouse effect as removing 7% of US fleet of cars from the road and it costs next to nothing.
Just because Bush doesn't sign up to a program with name recognition, doesn't mean the US government isn't doing anything.
Blaze a trail to the New World
I was unaware that there existed separate journals for each conclusion on politically controversial topics. Maybe you should learn more about how the peer review and journal submission processes work. Oh, and by the way, the article never said that "crank" journals were singled out and rejected. It said that any journal in the ISI was searched for relevant articles, and one would assume that the ISI does not include crank publications in its listings, and it certainly doesn't include non-peer-reviewed publications.
I agree that the scientific community has a history of being affected by groupthink and politics.
But, this is the scientific process. That community has come up with most of the innovations of the last few centuries, including the computer and networks you're reading this on. They can be and sometimes are wrong. But betting against them is not a smart bet. Especially with life as we know it on the line.
Books generally don't count since they are not filtered though peer review. The one you link to, "The Skeptical Environmentalist" has the distinction of generating some peer discussion in scientific magazines. The only problem is that the discussion has been unilaterally negative. At least he did get some arguments started, so hats off to him. But if he's serious about changing scientific opinion, he should (and maybe has) submit to peer reviewed papers. They may not be published, but that's where the true battle is waged.
-Ryan C.
Just because everybody is saying it, doesn't make it true.
But okay, I'm the last person to deny global warming is upon us. Other than some US folks still not convinced or thinking it's not that big a problem (or simply putting their head in the sand), global warming is observed, and the only question is about how much of it is the result of human activities, and how much by natural causes. Oh yeah, and what to do about it.
For the rest: nothing to see here.
This is a rebuttal to right-wing politicians' common claim that there is controvery in the scientific community about global warming. This is a lie, and it's the same tactic that creationists use to drive evolution from public schools. They claim that biologists are split on evolution, so it shouldn't be taught in schools. (In reality, there is only debate about certain details, like whether natural selection is the exclusive mechanism driving the observed process of evolution. No biologist worth his salt is going to dispute that evolution occurs.)
Except that the sea level won't rise if the ice caps melt. Ice displaces more volume than water.
That's not what was shown in the documentary 'Waterworld'...and hey, if melted polar ice caps means a world with Kevin Costner with gills, well then, bring it on! I loves me a good freak show.
Interesting conclusions, and they seem entirely valid. One thing I was wondering just last week, though: Astronomers point to a period of reduced solar activity (sunspots, flares, etc.) about four hundred years ago and say that this accounts for a "mini-Ice Age" experienced in Europe at the time. That is, without the flares sending huge amounts of radiation towards earth as they normally do, the quiet period on the sun lowered our temperatures significantly during that 80-100 year period (in the 1600s). No one is quite sure why that happened, nor can they predict when it might happen again, though at least a couple people have suggested something like a 400-year cycle, which would be some point in the next decade.
So the interesting question will be: How will our human-generated global warming (which they didn't have during the Maunder minimum four hundred years ago) affect the climate if temperatures already drop due to lower solar activity? Just something random (and hopefully interesting) to contemplate.
The world-averaged temperature could remain unchanged by cooling some regions and warming others, and both things could be difficult in terms of crop adjustment, etc. And there is a lot of concern about water as well as heat; think drought.
The expanded phrase also includes the "climate of weather", i.e. the slowly varying statistics of the quickly varying fields. For example, we ask whether the weather would be more stormy in the future.
I've never heard it said that climate change is a euphemism ... to folks like me who work in this field, it's a more encompassing phrase.
Bush didn't "pull out of" anything. Why YOUR revisionist history, Anonymous Coward?
The US is a Kyoto signatory, but "On June 25, 1997, before the Kyoto Protocol was to be negotiated, the U.S. Senate passed by a 95-0 vote the Byrd-Hagel Resolution (S. Res. 98), which stated the sense of the Senate was that the United States should not be a signatory to any protocol that did not include binding targets and timetables for developing as well as industrialized nations or "would result in serious harm to the economy of the United States". Disregarding the Senate Resolution, on November 12, 1998, Vice President Al Gore symbolically signed the protocol. Aware of the Senate's view of the protocol, the Clinton Administration never submitted the protocol for ratification."
All of this happened under Clinton.
So, sorry, but your bullshit post is just that.
Well, I HOPE you aren't anyways.
Yes, groupthinking like 2+2=4 and the earth is round, is just sooo bad.
How are mathematical statements and established facts groupthink? Groupthink is belief in an opinion or hypothesis because it is the most popular one. There is consensus based on scientific observation of climate data that global temperatures are rising along with atomspheric CO2 levels. There is actual evidence of this.
The evidence pointing to the CAUSE of global warming isn't so solid. All we know for sure is that CO2 and other greenhouse gases are heating up the planet. The impact of human activity on CO2 levels may be negligable for all we konw. One major volcanic eruption, for example, can pump out more climate-altering emissions in days than all of humanity could do for years. The observations in this article do not present any evidence at all, they just demonstrate that scientists who write papers happen to have come to a consensus that human CO2 emissions have an impact on global warming. Being there is not SOLID, DIRECT proof of that one might say it is "group think"...scientists have succumbed to "group think " before...
The article itself makes a good statement:
The scientific consensus might, of course, be wrong. If the history of science teaches anything, it is humility, and no one can be faulted for failing to act on what is not known. But our grandchildren will surely blame us if they find that we understood the reality of anthropogenic climate change and failed to do anything about it.
Science isn't always right. One thing is for sure though, reducing CO2 emissions due to the burning of fossil fuels might not stop global warming for sure, but it certainly can't make the problem worse. And besides that, it is probalby wise to conserve the worlds biggest NON-renewable resource, much of which happens to be unfortunately located in politically unstable countries where mentally unstable terrorists like to hide.
It is still surprising to me that only 1 in 4 bothered to include alternative polution sources...
Because they're professional geologists, so that goes without saying? These are peer-reviewed scientific journals, not introductory textbooks. If a physician writes an article claiming some chemical causes cancer, is he going to also mention everything else causes cancer? Is he going to mention the sun also causes cancer? Of course not, because he most likely is not a complete and utter moron, and he assumes his readers aren't either.
Find me a single geologist anywhere who has ever publicly stated that anthropogenic sources are the only things that cause global climate change.
Maybe this is just a nitpick, but people tend to overestimate the importance of humans and our impact on the planet. The issue here is our own survival. The opening of the article lays it out plainly:
Global climate change is increasingly recognised as the key threat to the continued development - and even survival - of humanity.
Exactly. The Earth will go on spinning and evolving new land masses and creatures as it has done for billions of years, no matter what we do to it, short of actually blowing it to pieces. Even massive global nuclear contamination would fade away eventually, becoming a mere hiccup on a geological time scale. Our activities might destroy a lot of species in addition to ourselves, but in planetary history mass extinctions are routine non-events.
What motivates my concern is not that we need to preserve this or that for its own sake, but that we want to maintain a pleasant world to live in. For some people that might include spotted owls and obscure mud lizards, for others not. I think the environmental movement might get more attention from the people who make the decisions if they give up on the sacred earth-spirit thing and focus on the fact that nobody wants to think of their great grandchildren living in shelters and subsisting on hydroponic fungi.
Of course, 600 years ago a "peer review" would call you a crank for saying the world was round.
There is human influence on the climate. The harder question to answer is to what degree and how fast? Most of the global simulations have some pretty fatal flaws. Some do not account for the oceans ability to hold heat very well. Others do not take into account how changing currents in the deep levels of the oceans will affect upper currents. Heck, the GFS[NOAA's main forecast model] had a 30 degree miss on the weather in New England this past weekend three days out. Computer modeling is not the be all end all.
This is not to say that nothing needs to be done. I think there is a bit of Chicken Little in the research community. Especially the ones who know that fear brings them more funding.
Some have stated Kyoto was a "start." In international treaties, there are no such things as starts. Once you get a bad treaty, you tend to be stuck with the damn thign forever because the other countries feel like they did what they needed to do. That is politics. You can not accept a bad treaty like Kyoto. It had major flaws and would have been a band aide on a monster gash.
Is the administration doing enough, hell no? However, Kyoto flat out sucked as a treaty goes. It had been rendered as nothing but a way for third world countries to make money by selling their pollution rights. It was full BS.
It is an undeniable fact, backed by a large volume of evidence, that the climate is changing worldwide. Whether or not we humans co-caused this, we will have to live with the consequences! And if we're sufficiently open minded about what is going on we may be able to mitigate some of the bad effects, or at least slow down these unwanted changes by pro-actively looking for "solutions".
I simply fail to understand how scientifically educated people can be so stubbornly blind to this simply because "they don't like the consequences"!

"The article started off with an ominous warning about climate change from the 1970s about...global cooling."
Not only that, but the "warnings" for global cooling and now global warming are coming from the same individuals. Can you say book sales? I know you can.
The climate is always changing. Sometimes it gets warmer and sometimes it gets colder. What is controversial here is 1) should we attempt to stop changing the climate if that is indeed what is happening, or 2) save our resources for adapting to the inevitable change?
If you think 1) is correct, then you worship Kyoto as the God that will Save Mankind (nevermind the fact that if the predictions are correct, and they are not likely to be, that Kyoto is only intended to reduce the INCREASE IN CO2 emissions by less than 10%).
Kyoto will do nothing to actually save us, but it WILL cause a huge amount of resources to be consumed. Somehow, environmentalists think that consuming resources to no good result is good IFF the intentions are good. You see this all the time. That's because environmentalism is a religion, and has nothing to do with science.

What Saddam did was in the middle of war; we are prepared at any time to fire nuclear missles at other countries, which just might be a bit worse on the environment than Saddam's oil fires. FYI when Saddam asked the US about invading Kuwait, Bush Senior's administration told him they had no opinion on the matter. Not that I'm defending him, but I can see how he might have been a bit bitter on his way out of Kuwait.

After the most recent Slashdot story I actually steeled myself to do something about it. I re-read the whole story at Threshold 2 to gather UIDs of people who might help. The idea is to build a list of myths and authoritative answers to them. For example, the old line that the sun's getting hotter, and that this explains global warming, comes up over & over again. Many, very patient! and knowledgable people posted to that story with excellent refutations of such nonsense.
I'm going to put my plaintext mail address in this comment, that's how serious I am about this! You can even help if you believe that Climate Change is hippie nonsense trotted out by pseudo scientists who just want more funding!!
What I am looking for:
If you have violent objections to the idea that global warming is a bad thing, please email me at the address below describing why you think this. As you will see if you hit 'see the rest of this comment', the existing list - which were collected from a single Slashdot story - is already pretty long, so this isn't so vital.
If you can help knock down such gibberish- if you have posted with a calm, well-argued and ideally knowledgable or carefully referenced refutation of a wild claim - please email me and make yourself known; I will get in touch in the next few days.
If you want to subscribe me to lots of spam lists, don't bother; Gmail are very good at spam filtering, you'll get yourself blacklisted when I hit 'report spam' and you won't be helping your cause one little bit.

>>Mt St Helens when it blew in the 80's? It blasted more toxins and pollutants into the atmosphere than mankind has since the beginning of the industrial revolution.
Uhhhh...no it hasn't. But then again neither I nor you are backing up either of our assertions with information...how many cubic kilometers of dust and ash were release? Not sure? Go pick up a study and read up on it.
likewise...if you're unsure of any of the global warming studies done out there...go find one...and read it! Some are very dry, and boring for many I assure you but the science is there...and it doesn't lay out a concrete series of future facts. Science as always only draws lines from parallels of known data.
As a Canadian I know it's going to be national concern #1 very soon because we've let atrophy our navy and the arctic sea ice is disppearing so fucking fast that we're going to have to build 10 to 15 ship armada just to police all that new open water. Other nations have even started planting rogue flags to claim territory we haven't been using.
in the end all our posturing is psuhed aside by cold hard fact...Earth warms = less sea and land ice. That is happening now.
I think he always pronounces it "nucular" in public addresses. "Nucular" is an incorrect but very common pronounciation of "nuclear"; as this dictionary entry explains, it's common because so many other terms (circular, spectacular, molecular, ocular, vascular) end with a "-ular" sound, whereas "-lear" is comparatively unfamiliar.
An analogous word would be "minuscule", very commonly misspelled as "miniscule", because so many familiar words begin with "mini-".
All employees must wash hands before seeking equitable relief.
I saw this article on the front page and wondered to myself if there would be yet another stream of comments denying that there is evidence of climate change or that it could have any deletarious impact. Of course there was.
I am a scientist, not working directly on how anthropogenic activities are effecting the atmosphere but on what the predicted effects may have on vegetation.
As a scientist I look at all the available evidence for a question and come to some conclusion based on that evidence. There is no other sensible way to make a decisison. Where the evidence is lacking, I would try and do some work that would provide evidence one way or another.
Virtually all available evidence points to anthropogenic emmisions causing climate change and there is plenty of evidence as to what those changes may be and what the effects of those changes on the biosphere may be.
Consequently, what I wonder about the, extremely predictable, Slashdot response to an article such as this is whether it reflects the attitude of the US or whether it reflects the attiude of the predominently young, middle-class and technical readership of Slashdot?
Either way, I'm fearful of the general ignorance and lack of logical thought.
Si hoc legere scis nimium eruditionis habes.
Don't get me wrong. I am not saying that scientists are any different than most human beings. Individual scientists can succumb to greed, lust for fame, etc and, occasionally, will get away with publishing intentionally erroneous data. Usually when this happens, especially in an area where so many scientists are working (like climate change), their lies will be uncovered and they will be ruined (ex: cold fusion, etc).
The article being discussed here states that the vast majority of hundreds of studies on the subject have all come to the same conclusions: global warming is both real and anthropogenic. I suggest that the groundswell of /. opinion that all these researchers are wrong/lying is due to the rather unfortunate consequences of the truth. We will have to face the facts that our climate may change. Maybe for Canadians, this will be a good thing. For ocean algae and those in the lower lattitudes it will most certainly be bad.
Society invests a huge amount of money in scientific research each year, and does so in a way that ensures maximum objectivity and honesty on the part of the researchers. Averaged over time and sufficient numbers of studies, science usually hits pretty close to the mark. Therefore, to all those doubting, suck it up and deal with the damage we've done. Don't blame the messenger if you dont like the message.
(1) there has never been any doubt that human activities contribute to global warming. The only point of contention is wether an alteration of our current activities would cause a significant change in the rate of global warming, and wether, if this is the case, we should attempt to do so.
(2)Consensus has nothing to do with truth... unless you subscribe to the WOD view of the universe, in which case we could fix all our problems by believing at them really hard.
Good to know that human foolishness is once again aligned in a predictable direction, though.
...it's really a sad day for America when we require a goddamn ACT OF CONGRESS to make our DVD players work properly. ~
Science is founded upon doubt--constantly challenging existing theories in search of physical truth. Considering most predictions concerning the earth's climate are based on poorly performing computer models, current theories are far from conclusive. Check out Patrick Michaels http://www.cato.org/people/michaels.html.
By asking this question you raise doubt about the quality of the work without actually presenting evidence that only a minority of the scientists do serious work on this. But if you are driving an SUV a statement like that might seem insightful even though it's completely void of information.
what wonderfully circular logic. don't question an article for its lack of information, as doing so is devoid of information. wow.
Benny Peiser, a senior lecturer in Social Anthropology & Sport Sociology at Liverpool John Moores University and the editor of of CCNet (Cambridge Conference Network) webzine, labeled Oreskes' essay a disturbing article.
"Whatever happened to the countless research papers published in the last ten years in peer-reviewed journals that show that temperatures were generally higher during the Medieval Warm Period than today, that solar variability is most likely to be the key driver of any significant climate change and that the methods used in climate modeling are highly questionable?" Peiser asked.
"Given the countless papers published in the peer-reviewed literature over the last ten years that implicitly or explicitly disagree with the hypothesis of anthropogenic global warming, one can only conclude that all of these were simply excluded from the [Science Magazine] review. That's how it arrived at a 100 percent consensus!" he added.
According to Peiser, Oreskes' assertion that there is a 100 percent consensus about the issue is not backed by science.
"Even [former Soviet dictator Joseph] Stalin himself did not take consensus politics to such extremes," Peiser explained. "In the Soviet Union the official 'participation rate' was never higher than 98-99 percent.
"So how did the results published in Science achieve a 100 percent level of conformity? Regrettably, the article does not include any reference to the [unpublished?] study itself, let alone the methodology on which the research was based. This makes it difficult to check how Oreskes arrived at the truly miraculous results," he added.
There's no time to stop for gas, we're already late.
The Earth is decidedly NOT in "serious, imminent danger". The planet is going to be just fine for quite a while, as far as anyone can tell. Get it right. Life on Earth might have a hard time adjusting to rapid climate change, but that's happened before, and life (and, yes, the planet Earth itself) has continued to exist. The REAL question (as the discussion appears to notice) is how much of this climate change do we have control over, and what should we be doing to keep ourselves out of trouble?
Time for rampant hedonism and fornication. We're all doomed.
Can we get an exact date on the doom? I want to start the bacchanalia about a week before, so as to optimize my avoidance of consequences.
It's rare that you're presented with a knob whose only two positions are Make History and Flee Your Glorious Destiny.
Simple point is that a scientific consensus has not always been the most accurate thing in the world.
Simple point is, that science in the way we know it today is a thing developed during the 19th century. Before it there was knowledge, there was lots of speculation and there was no separation between hypothesis, theory and fact.
Even the great scientist of the late 17th and early 18th century, Isaac Newton, was more interested in alchemic experiments and metaphysical speculation than in the Physics and Mathematics where he laid the fundamentations for today's Calculus and Mechanics.
Today's scientific consensus is still lacking, and it is no replacement for a thoroughly tested theory. But it is the best thing we can get, if said theory is still missing. Just because it's not perfect you shouldn't just throw it away.
this criticism is pretty slack. it ignores the point of Crichton's diatribe - that being concensus is often used when there's no hard supporting science - in favour of a rib jab. E=mc2 is a quantifiable equation, as is the distance to the sun, and the effect of malnutrition. human affect on the environment, on the other hand, is not honestly quantifiable as the historical data is severely lacking in context. regardless of the simple fact that i'd look sideways at any scientist that claims we're not affecting the global climate, i'd probably look *down* on a scientist that claims it's proven.
does that dismiss human affect on climate change? absolutely not, but there are people who believe that questioning an absolute certainty of it does dismiss it. they're wrong, they're arrogant, and they're not learning from history.
Jesus told Bush it's all part of the Rapture, so don't worry about it.
Any time you see every scientist agree...
All scientists agree that the Earth is round.
All scientists agree that the sun is made up of Hydrogen.
All scientists agree that gravity pulls things down.
All scientists agree that smoking is bad for you.
All scientists agree that splitting the atom will produce energy.
Why is it that when all scientists agree that human activity is having an effect on Global Climate, all of a sudden your hear all these people begin to doubt them. Claiming that all that these scientists care about is their funding is ludicrous, because many of them will get funding either way. Of course, those that are really into money, like Bjorn Lomborg, will actually argue against the mounting evidence. In exchange they'll get huge grants from industries whose profits might be diminished by scientific enquiry. And those who doubt only when scientists challenge their love for their SUVs, like ostriches, will be happy to put their heads back in the sand and say: see, there's a couple of scientists who say that Global Climate change isn't happening. They must be right!
Personally, I'd rather not take the chance. If Global Warming has only a 10% chance of being true, then the odds are still way too high, because the consequences are catastrophic.
So, in response to you, I say that if every scientist agrees (or at least no scientist disagrees) that Global Climate Change threatens us, then we should be very concerned. We should fund their studies, and if we find out that they misused the funds or overstated the threat in order to get more money, we can always cut that funding. In other words, unlike the most catastrophic scenarios linked to Global Warming, it's a reversible mistake.
Better safe than sorry, especially when the future of humanity is at stake.
Reminder: find a new sig
Unlike Christianity, science is not a religion. The "truth" is based on the basis of observation and data. If someone had compelling data that say North American deforestation was a natural process and not due to the timber and pulp industries cutting of trees and conversion of that land to agriculture, industry, and mini-marts, it would be published. In this case as in the case of global warming there is compelling evidence that there are human factors.
If scientists cannot agree whether mean temperatures will rise by 3 degrees or 5 degrees, it is not particularly fair to dismiss their theories outright.
Sound policy in my opinion would be to immediatly consider at least the easier reductions in our emissions. It certainly won't harm anything. In the decades when some were in denial of the harmful effects of smoking would it have been unhealthy to quit?
When the people fear their government, there is tyranny; when the government fears the people, there is liberty.
"In other news, 75% of the owners of McDonald's franchises believe that including McDonald's in your diet is not a bad idea. The other 25% had no opinion but that may be because they didn't stop munching on their Big Mac.
This is not surprising at all. Very few human beings bite the hands that feed them and scientists are human--those in academia are especially human and especially political. They're not going to be out there proving that global warming isn't happening or that it is a natural phenomenon when doing so, in sufficient numbers, will guarantee that funding will dry up on the topic and they'll have to find another research gravy train.
This also doesn't consider how many studies may have been done, submitted for publishing, and rejected. This could be just as much a political condemnation on those that decide whether or not a study is worthy of being published as it is any comment on the validity of global warming and/or its possible human sources.
Any time you see every scientist agree (or at least no scientist disagree) on a very controversial topic, be very suspicious.
"
And your basically saying "I have no credible proof of my side of the agrument, so it must mean all the credible proof is magically hidden from us".
There as much money to be maid refuting global warming (Halberton and the auto-industry would dearly love to see a credible study refuting climate change) as there are supporting global warming.
"There are more things in heaven and earth, Horatio, than are dreamt of in your philosophy."
Not really. But even if you found some funding (probably from a corp) to do some research in a 'forbidden' direction, try getting your conclusions published in a peer reviewed journal. Won't happen.
It won't get published for reasons such as poor methodology, maths etc. Not because you view is 'forbidden' or not politically correct. You are simply suffering under a conspiracy theory view of Science if you believe otherwise. In fact, while perhaps not in Science, oil-industry funded research, and some not funded by the oil industry, which argues against the consensus of climate change, has been published. It's rare, true, but this rarity is because the bulk of the evidence points in the opposite direction, not because of some grand conspiracy aimed at ensuring funding for climatic research.
> What's controversial about this issue? By asking that question it is clear no rational discourse is possible with you, you too are a religious zealot.
I'm neither religious, not a zealot, and it's called a rhetorical question. I'm asking (as should be clear from the rest of the passage), "where does the controversy here come from?" My point is that there is little scientifc controversy. The controversy is largely injected at the political level.
Hopefully others reading this thread are less invested in the theory to reject all discussion out of hand on the issue.
Again, I'm not going to reject out of hand any discussion based on evidence and a scientific understanding of that evidence out of hand. Quite the opposite, I genuinely hope that we are all wrong! I hope to wake up tomorrow and that it was all a bad dream, a mass delusions of the world scientific community caused by some faulty maths somewhere down the line. And you know why I hope this? It's because, at our current state of knowledge, the conclusion that we are headed for a very nasty time climatically is ineluctable and because I have children. But I'm not going to stick my head in the sand on this one.
[I]f one is politically aware, one notices that the loudest voices in the Global Warming crowd also want to dismantle Western Civilivation
I consider myself fairly politically aware, but I'm quite unable to see how shifting from oil to uranium amounts to a dismantling of Western Civilization. Perhaps you can clear that one up for me? Again the opposite is true, it's through technological advance alone that we are going to beat this one. We have to move away from this C19th energy source.
You might want to think of someone other than yourself for a change. Our children and our children's children maybe...
The race isn't always to the swift... but that's the way to bet!
I knew that was coming when I posted it. That's why my original post was written "Any time you see every scientist agree on a very controversial topic, be very suspicious." The issues you mentioned are not controversial.
Convenient quoting on your part. Usually indicative of an agenda.
Why is it that when all scientists agree that human activity is having an effect on Global Climate, all of a sudden your hear all these people begin to doubt them.
If all scientists truly agreed that human activity is having an effect on global climate (lower case is fine) then I don't think you'd have a lot of people doubting them (not just beginning, we've doubted them for a long time!). The fact is that all scientists do not agree this is true. The only thing this article proves is that the collection of articles they selected from the subset of scientific literature that they deemed worthy of reviewing supports their conclusion. You don't even have to be a scientist to recognize just how hokey the whole basis for this article is.
Claiming that all that these scientists care about is their funding is ludicrous
I'm not claiming it's the only thing they care about. But you're naive if you think it doesn't enter their mind.
Oh really? Who is going to fund research proving that global warming is not real. Industry, that's about it. So they'll be quickly labeled an industry stooge by their colleagues (just as you did in your message) and their standing in the community will go down. Not because they're wrong but because they're going against the grain.
And those that would (or would have) funded research to prove that global warming is not ocurring has already done that. We know that there is a lot of doubt regarding global warming. Anyone with an open mind and critical thinking skills can recognize that there is more than reasonable doubt as to the accuracy of the predictions of the pro-global warming crowd. As their models become "more accurate" their predictions of natural calamities slowly become less and less severe. And they spend more time engaging in gloom and doom and explaining why the satellite record doesn't confirm their predictions than actually getting real science done.
In exchange they'll get huge grants from industries whose profits might be diminished by scientific enquiry.
Or by "junk science." Take your pick of terms.
Personally, I'd rather not take the chance. If Global Warming has only a 10% chance of being true, then the odds are still way too high, because the consequences are catastrophic.
Sorry, that's extremism talking. If there is a 10% chance of it being true and it's going to cost a trillion dollars worldwide to fix the problem then we had better be avoiding at least $10 trillion worth of damage. If not then it was not a worthwhile investment. It may be cheaper to just move the people that live too close to the ocean than to try to keep the ocean from rising and pay a little more in insurance for the supposedly more frequent severe storms.
Not to mention no-one really knows what the consequences of global warming is if it's true. All we have are models created by scientists that find themselves, quite frankly, in a position of power and public importance that scientists would not normally find themselves.
So, in response to you, I say that if every scientist agrees (or at least no scientist disagrees) that Global Climate Change threatens us, then we should be very concerned.
> You are simply suffering under a conspiracy theory view of Science if
> you believe otherwise.
Ignore the political biases of the Global Warming crowd, ignore everything but blatent self interest, and unless you want to be laughed at you must admit that scientists are human and subject to act in their self interest. At this point in the game, if someone DID debunk Global Warming and managed to get published, how many climatologists would still have careers since every last one of them has staked their professional reputations on this theory being fact? No, at this point is is illogical to expect reason from the scientists on this issue. Religion clouded their judgement and now they are in too deep to even consider whether they were wrong.
> Again, I'm not going to reject out of hand any discussion based on
> evidence and a scientific understanding of that evidence out of hand.
Ok, then consider these items:
1. Sunspot activity has been increasing over most of the 20th century. If Mr. Sun is responsible it is natural climate change.
2. To the best of my knowledge, No computer models exists that can be loaded with 1900 and then allowed to run and produce the 20th century without a lot of unexplained fudge factors to make it come out right. No model exists which has been allowed to run into the future and then checked with what actually happened a decade later has produced a match.
3. Very few records of long term tempratures exist where the measuring station is not now inside a urban heat dome.
Taken together, just those three items means we can't say with confidence the temp is actually currently rising globally, and even if it is we can't say whether our actions are responsible. And we can't make any sort of meaningful predictions as to how much it might go up, whether other forces will act to accelerate or moderate any rise, etc. Basically all we CAN say is global and regional tempratures change over time and they may or may not be changing now.
Yes there is also a lot of very compelling evidence on the other side, but not enough to call the matter settled, and in my opinion not enough to justify preemtive war against ourselves that will certainly cause massive social and economic harm.
> I'm quite unable to see how shifting from oil to uranium amounts to a
> dismantling of Western Civilization.
Why not call for Fusion power while you are at it. Too many (so called) Scientists are just as religiously opposed to anything related to the N word to seriously consider it as an option. To get a paniced retreat from fossil fuels would require the Global Warming zealots to be in political ascendence and that means they would say no to more reactors.
I'd say build reactors to get us away from depending on Middle Eastern Oil, and that argument is equally valid whether Global Warming is real, natural, wrong or an outright hoax. And if the Earth does start warming we can always just orbit some mylar sheets and block a fraction of a percent of the Sun until we rebalance, problems we create by being overly clever primates we can probably fix the same way, especially ones that operate over such a long time horizon.
Democrat delenda est
What I am trying to say is, people have made careers out of studying global warming. If they all suddenly came out with research showing that global warming doesn't exist or is naturally occurring, it would be the end of their careers. Grant money would dry up. Most people are unwilling to self-terminate their careers, so they engineer research (intentionally or not), that will assure them more grant money and continuance of their field of study.
As has been pointed out above, there is more money out there available to people to want to show that global warming is not a result of human activity. If you could come up with a plausible mechanism which explains the observed climatic changes, and totally discounts anthropogenic causes, you would not be wanting for funding.
In any case your reply is not really pertinent to my post. Your theory doesn't explain, for instance, the climatic change that has already been observed, nor why the insurance industry (which does not fund itself by grants) is so concerned about the impact of climate change.
Scepticism is ususally a very healthy thing. When it is coupled with a conspiracy theory, however, it can be pathological. It really is a bit late in the piece to be indulging in this kind of fantasy my friend.
Better to be despised for too anxious apprehensions, than ruined by too confident a security. --Edmund Burke
Are you utterly clueless? Have you seen the Los Angeles skyline, or worse Mexico City? Decreasing emissions is beneficial whether or not they cause global warming. The first thing the government should be thinking about is the health of the people, not the economy.
Time makes more converts than reason
- Scientists think about funding, but pushing an agenda to acheive funding is ultimately a career-limiting move when the political pendulum shifts, as it has in recent years. And as with most things, the scientific ego supercedes the need to seek acceptance through funding - scientists will push theories they believe in, and try to swing funding their way, not vice versa.
- Have you actually read any of the literature regarding climate change? It doesn't sound like it - you don't see much politicizing in peer-reviewed journals. Certainly the exacting of personal/institutional spats occurs, but the literature certainly doesn't read the way you imply it does.
- I don't think stating that no scientific paper reviewed discounts anthropomorphic climate change will have a chilling effect on climate research: scientists are well aware that correlation is not the same as causation, after all. When reliable evidence that supports the theory that climate change occurs independent of human activity surfaces, it will be published. When reliable evidence that supports the theory that climate change occurs because of human activity, it will also be published. Until then, we'll continue to study the mechanisms behind climate change and look for links. It's just that simple.
- The Science article merely states that the bulk of peer-reviewed literature allows for the possibility of anthropogenic climate change, nothing more. Anything you read into it sounds more like your agenda than anything else.
Anyways, take it as you will - I doubt seriously you're prepared to think critically about this topic. But making blanket statements accusing scientists of massive malfeasance to further a political agenda that counters your own smacks more of conspiracy theory than a reasoned argument, and it certainly doesn't impress the average scientific Slashdot reader.But what does my opinion matter, I just vote here. It's not like I have any money or anything.
Ignore the political biases of the Global Warming crowd, ignore everything but blatent self interest, and unless you want to be laughed at you must admit that scientists are human and subject to act in their self interest.
I started off by arguing that self-interest would lead scientists from accepting the much more lucrative funding which is available to the skeptics. In any case you cleary are indulging a consipracy view here, which leaves little room for sane discussion, so next topic.
Sunspot activityYou really believe this isn't (has been) incorporated into the models?
No computer models exists that can be loaded with 1900 and then allowed to run and produce the 20th century.Two things. 1. Agree, computer models are just complex models. I'm unconvinced that the specific predictions being made will come to pass. On the other hand, it is beyond doubt that singificantly altering the constitution of the atmosphere will have climatic implications. It is also beyond doubt that climatic changes, which are not inconsistent with theoretical predictions are being observed. You need also to remember the geological record.
2. Your statement seems to indicate that you are confusing a model with a simulation.
Very few records of long term tempratures exist where the measuring station is not now inside a urban heat dome.A valid argument in 1989, but no longer in 2004. You will find peer reviewed papers from this era pointing that out (which argues against your conspiracy theory). In the meantime the instrumental record has been corrected for this effect. There's no longer any doubt about warming. Nowadays even the most extremist skeptic only argues about the anthropogenic nature thereof.
Why not call for Fusion power while you are at it.Simple. It's not a proven technology (or any technology). I might as well called for solar, wind etc. power. But you haven't answered my question, which was "how does moving from oil to uranium amount to a dismantling of Western Civilization?"
Being overly clever primates we can probably fix the same way, especially ones that operate over such a long time horizon.Yes, but what about immediate time problems like global warming? We think we are overly clever primates, but the very fact that we are still arguing about whether a problem exists, rather than getting on and fixing it would seem to evidence the opposite.
All scientists that I've met have, thus far, been human.
:)
:)
:) But laugh if you will.
:)
Man, could I show you a thing or two, then...
"Think twice about publishing your anti-global warming research because everyone disagrees with you."
Again, you're not reading the literature. Plenty of people win their spurs from publishing theories that dispute anthropogenic climate changes, or by positing hypotheses that negate any warming that might occur. Google for the 'Iris Hypothesis' by Richard Lindzen - makes for great reading, and even better back-and-forth literature articles. FWIW, not even Lindzen out-and-out discounts global warming, but he obviously doesn't think much of it, and he's done just fine from publishing his research.
At no time in human history have scientists had so much influence on politics as global warming scientists do today.
Yeah, because everybody signed that Kyoto Accord and put it into action, right? C'mon - your statement is ludicrous and you know it. Scientists have little influence on politics unless they've found a way to blow people up.
So why the hell did Science publish this silly article that proves nothing?
To sell ads, maybe? To encourage further discussion from the scientists that suspect that global warming is hooey but haven't found proof yet? To keep the thing interesting? Scientists read dozens of new articles every month, and a little light entertainment is sometimes just what the doctor ordered.
We already know that climate change occurs independent of human activity. Or are we to believe that the climate was static until we humans started messing things up?
No, no, no, read that carefully now. What I said was no paper has been published which posits that climate change is (as in, is now) independent of human activity. Certainly before humans existed, climate change was independent of human activity. The global warming debate boils down to whether or not this is still the case. Stop playing semantics.
Althought right now we aren't really discussing global warming but whether every scientist agrees with it.
Again, that's not what the Science article says. I know plenty of scientists who are skeptical about anthropogenic climate change (I myself have reservations about the magnitude of any human impact) but, that doesn't mean that we don't agree that global warming is a possibility. Why? Because nobody's proven otherwise. Neither do we necessarily believe that global warming must exist (which is what you think the Science article claims) because again, nobody's demonstrated the link past a first-order radiative affect.
The average scientific reader of Slashdot? Hahaha.
You should have gleaned this by now, but I mean what I write when I write it, because I try to write carefully. I didn't say the average scientific reader of Slashdot, I said the average scientific Slashdot reader. The former puts the emphasis on 'reader of Slashdot' while the latter puts the emphasis on 'scientific'. There's plenty of scientists who read Slashdot, and more often than not, we wonder why we even bother when we read the comments. No doubt some other scientist is out there rolling their eyes at my charging at windmills, but hey, this is what I do after a few whiskey sours.
Anyways, this is a tempest in a teapot - the Science article merely states that there exists a scientific consensus that global warming hasn't been disproven. Perhaps their angle is suspect, but nothing else, and I wouldn't get all hot and bothered about it if I were you.
But what does my opinion matter, I just vote here. It's not like I have any money or anything.
Most people don't feel like spending green on being green. They'd rather have a plasma TV set.
I bought a $1300 fridge that runs on $40 of electricity a year. Extra insulation, new design, better motors, whathaveyou.
Now the payback period on that is almost ten years. Worthwhile as the fridge should last at least that long. But in the meantime I've lost opportunity on that money and I don't have a plasma tv set.
My God, it's Full of Source!
OUTSIDE_IP=$(dig +short my.ip @outsideip.net)
Since I don't feel like finding another post to attach this to, here's a response to a couple of other points:
1) Forget the whole theory that global warming is simply an artifact of urban heat islands. We fixed that particular problem with the data in the early 1990s. The urban heat island effect is without a doubt the best-understood phenomenon in climatology, and even with the effects removed climate is still warming.
2) Sunspot activity doesn't explain most of the climate change story either. It's part of the story, but definitely not all of it. If you want to check out a paper on the subject, I suggest the following (I know its a few years old, but the findings haven't changed subsantially since this paper):
Cedric Bertrand, Jean-Pascal van Ypersele, Potential Role of Solar Variability as an Agent for Climate Change, Climatic Change, Volume 43, Issue 2, October 1999, Pages 387 - 411
note: I'm not telling you to believe the paper. Just to read it. If you understand enough about what's going on to do so, please feel free to poke holes in it. That's part of science.
Wow, that's an impressive wall you've constructed around your mind to avoid confronting the truth.
First you start with "There you go again, implying that only those that question global warming could be influenced by vested interests. That's just plain naive." So I'm reading this, and I figure I'll be conciliatory, and grant that, yeah, even though that's not what I said, it's a big world, billions of people, lots of vested interests in it, so I'm sure there are at least some vested interests to be found on both sides of any issue, even a severely lopsided issue like this one where all the scientists in the world are on one side. I don't want to appear "naive", you know.
But that was a mistake, because then you shift right into "gotcha" mode: "So there are vested interests behind the neutral observers and scientists? Just how neutral and scientific are these people supposed to be when they are backed by vested interests? That's kind of like expecting a Microsoft employee to be vocally supporting Linux."
You guys are like unsinkable rubber ducks.
Scientific debate is good but there are two possible reasons why something is in very high agreement:
The first option is unlikely, and in this instance, wrong! There are several noted studies that "show" that global warming is not really all that bad, is normal, or that there just isn't enough evidence to support it at this time. Unfortunately for them, these guys are the ones who really are paid for their opinions by oil companies and their subsidiaries. Google this to find what I'm talking about or attend a presidential press conference.
However, funding for the ones mentioned in this study does come from many different sources for the people that are finding there is evidence that we are now in global warming. Again, Google if you want to find the different organizations involved.
So, when you have an agreement on the meaning of given evidence from many sources that use good, sound, scientific reasoning to come to their results, you have what must be viewed as a high likelihood that the conclusions reached are correct.
In other words, since it isn't essentially one source/industry paying for the results; since the opposing viewpoint is paid essentially by one industry and frequently is viewed by suspicion by the academic review process, the only option left with any high degree of certainty is...
2 - They're coming to the same conclusion because that conclusion is correct!
It helps that good science is impossed but I'm sure someone will point out how nearly unanimous scientific agreement has been wrong in the past. So I'll just say that it is highly likely but not certain that we are experiencing global warming / greenhouse effect right now.
If you don't feel that's the case, go out and smoke a few gross of cigarettes for many years and find out if, indeed, cigarettes don't cause health problems such as cancer. Same type of argument exists there too.
but at core, Global Warming is religion
You are using a conspiracy theory to argue against a scientific theory. You may be right but your arguments are less than rigorous.
I would like to see some actual scientific rebuttal of the available evidence for global warming (and there is some, Ice cores, melting glaciers etc. Also there is no doubt that CO2 levels are much higher).
Fight science with science. Not just a conspiracy theory.
Definitely worth a read: http://www.lomborg.com/ for a solid statistical analysis of environment trends. Also I don't think the mathematical analysis underlying the classic global warming curve stands up to analysis. Just because a whole lot of people believe something doesn't mean it is true.
The ozone either breaks down in time, or absorbs some more UV, and breaks apart again. The real defense against UV is the O2, NOT the 03!
Did they teach you about two things called rate and equilibrium?
You are correct in remembering that
3 02 + UV -> 2 03
but also
CFC + UV -> Cl* (Cl radicals)
and then
Cl* + O3 -> ClO* + O2
ClO* + ClO* -> Cl2O2
Cl2O2 + UV -> 2Cl* + O2
overall: 2O3 -> 3O2
Chlorine is very effective in catalyzing the decomposition of O3 into O2 faster than UV can turn O2 into O3. Given a constant flux of UV, the equilibrium concentration of ozone relative to normal oxygen is much lower in the presence of chlorine radicals.
If Global Warming has only a 10% chance of being true, then the odds are still way too high, because the consequences are catastrophic.
Catastrophic? - How do you (or anyone else) know that?
It is an undiputed fact that the Earths climate has been wildly different at different times through the eras and life always managed to survive.
It is also a fact that man is the most adaptable living creature ever discovered; we've been able to live everywhere on this planets surface, plus in the air, under the water and even in space and on the moon. We as a species will survive any climate change given enough warning to adapt (using technology if nessesary).
Now IMHO instead of blindly trying to return the climate state to the level of 'the good old days' we should rather accept the changes (which still may be natural, and which in any case has happened naturally before and may again) and begin the adaption process. The sooner the better.
Sure, things will be different but it doesn't mean it'll be worse (or catastrophic), and it might even be a change for the better in way we cannot imagine at the moment (due to lack of data).
"For every complex problem, there is a solution that is simple, neat, and wrong." -- H.L. Mencken (1880-1956) --
All scientists once believed the Earth was flat, was supported on pillars or carried by Atlas etc.
Ah, I see your problem. You are confusing "scientists" with "religious nuts". The former base their theories on observations and critical thinking while the latter just go on wonky rants for no reason whatsoever.
sigs are hazardous to your health
is that all these are consensus despite the evidence, global warming is a consensus because of the evidence.
No, but all too many 'scientists' are Gaians or worse.
Some scientists in the environmental areas do subscribe to the Gaia Hypothesis, but even that has many levels. At it's most basic it means treating the whole ecosystem as a macro-organism. It doesn't mean you think the Earth is one living creature, or you are some tree-hugging hippy, just because some of those people believe in the more extreme end of the hypothesis.
Of course they are the only voices you will hear in the mainstream press.
You must have missed that whole Slashdot thread based on a Wired article, about how media's desire to show both sides of the argument in cases like global warming meant they had to hunt around for people on the "humans have no effect side". The mainstream press was out there looking for these guys, but all they could find was people in the pay of companies. The whole thing was about how they got a disproportionately large amount of media coverage in the name of balanced reporting.
Or the scientific papers, because dissenting voices can't make it past peer review and scientists being generally above average in intelligence know this so would tend to not bother attempting to publish a career ending paper.
Proving the rest of the scientific community wrong is about the best career move you can make. Scientific history is full of examples, indeed, the whole scientific process relies on it. Science establishes a consensus, until there is sufficient evidence against it,
If nobody brought up anything against the current scientific consensus, science would never move anywhere. Your tinfoil hat ideas about how science work just undermine your whole credibility.
If a proven danger to thee, me and everyone exists, then yes our government then has a duty to act in the common defence as provided for in the Constitution.
It would be nice if life always gave us all the information we need before making a decision. Sometimes though, it doesn't. You have to try and assess the risks, and potential consequences, if you wait too long for proof, it will be too late.
Unless you happen to be one of the ones who loses their livelihood in the economic chaos that signing Kyoto would bring.
Because all those other countries that signed up are head straight for economic chaos, right? Kyoto has flaws, but those aren't an excuse for doing nothing because you don't want to upset big business. It looks to the rest of the world like the US Government isn't just showing some scepticism, which would be no bad thing, but sticking its fingers in its ears and going 'la la la' to the topic. As irrationally opposed to the concept as these fiendish "worse than Gaian" types whose danger you highlight for us.
This is pretty offensive. Research is not a "gravy train": it's something we do because it's stimulating, challenging and interesting. Scientists don't want to spend their lives working on ideas that they know are wrong.
That's not to say that they we are never wrong, and many of the greatest leaps in our understanding came about when someone went against the general consensus. However, what you're suggesting is that scientists are wilfully suppressing the truth because it's in their own personal interest.
There is an excellent response to this point later in the thread, by someone involved in scientific publishing.
Why? The subject is only controversial because (if true) it means we have to make some painful changes to our lifestyles. Just because that's hard to swallow doesn't make it a conspiracy by the scientific community.
Oh, wait, none of that happened. So why are you claiming that scientists are close-minded?
There are a few things that are known beyond any principled denial:
- Earth is roughly 50 degrees F warmer than a body with its absorptive characteristics would be at our distance from the Sun, absent other influences. (Venus is an extreme example.) This proves the greenhouse effect.
- The greenhouse effect is due to a number of gases in the atmosphere, including carbon dioxide.
- Adding more greenhouse gases to the atmosphere, particularly non-condensible ones, will have a warming effect on the Earth.
Now, you can have principled disputes about the interactions of mechanisms at work (greenhouse vs. reflective clouds), but you cannot deny that increasing the concentration of the most important non-condensible greenhouse gas by a large fraction is certain to do something. I see you dismissing the entire concept as religious dogma; it appears to me that your dismissal is itself dogma, like the political attempt to dismiss evolution from biology classes.You also engage in non-sequiturs.
You are using a claim of economic damage to deny a scientific conclusion which suggests a need for action. Well, gee, if I posit a scientific conclusion about the way that cholera and typhoid are spread it might suggest a need for billions of dollars of investment in water treatment systems! Our budgets are too tight, so by your "reasoning" my conclusion has to be wrong.Or maybe it's time for you to realize that the world isn't always as you like it. In other words, grow up.
Time is Nature's way of keeping everything from happening at once... the bitch.
Can you? Or your thinkalike buddies?
Even if I grant that global warming is occurring, do you have a shred of proof that things like the Kyoto Protocol will result in a net benefit to the welfare of most people? Ever hear of unintended consequences?
Poverty kills, and if there is one thing we can take as near certain based on experience, it is that collectivist prescriptions from the watermelon Left will result in increased poverty and misery.
Too much Law; not enough Order.
Ok, if you put it that way, then I guess the duty comes out more on the lines of "know enough to judge who actually knows what they're doing". For instance, simple empirical test tell me that the 'expert' who tells me what the wether is going to be like tomorrow is unreliable at best, making his analyses useless. Likewise, I know that I can trust the guy who built my house on how to build houses, because my house hasn't fallen down yet. The ideal, the state to be achieved, is to be educated enough in the everything to be able to make that kind of call with everyone.
Yeah, it's practically impossible. But I'm getting closer every day. And if I can't judge the reliability of my source, I just refrain from judging the analysis as well.
In all honesty, you seem to do the same thing, you just have a more regular criterion for trusting people's judgement. If "it's their *job* to study it" then you accept. I guess that's more efficient than my way, but I'm going to hold off on adopting it, as it would force me to become a member of at least 100 different religious groups. After all, it's the *job* of a fundamentalist southern baptist preacher to tell me what god wants, but I'm still not entirely certain of his assessment that the world will be a better place if we burn out all the gays and non-whites.
Just my 2 cents, eh.
...it's really a sad day for America when we require a goddamn ACT OF CONGRESS to make our DVD players work properly. ~
Has it occured to you that the greenhouse gasses keep the heat trapped at the lower portion of the troposphere, away from the satellites?
