2006 Was the Warmest Year Ever
kpw10 writes "Dr. Jeff Masters from Wunderground has a great summary of this year's rather abnormal weather (his blog is the best source on the net for in-depth weather analysis). The post discusses some of the cyclical climate forces at work this year and compares this year's record temperatures to records from the past. There are some interesting differences, particularly in the extent of the northern hemisphere seeing record highs this year." From the article: "December's weather in the Northeast U.S. may have been a case of the weather dice coming up thirteen — weather not seen on the planet since before the Ice Age began, 118,000 years ago. The weather dice will start rolling an increasing number of thirteens in coming years, and an ice-free Arctic Ocean in summertime by 2040 is a very real possibility..." Here is the The National Climatic Data Center's report announcing the entry of 2006 into the record books.
are either closed or operating at significantly reduced loads. Hell, some of the places in Austria are suggesting hiking trips instead of skiing this year. Here in Bavaria, we had(so I'm told) one of the coldest winters in the past 20 years last year, and this year I have only had to deal with frost twice(which is nice because I am on a bike)
Meanwhile Colorado seems to be getting more snow than the rest of the world combined(I'm only being a tad dramatic there). They probably have the best skiing in the world this year, but the airports are always closed so nobody can get there!

As, probably, the most powerful country on Earth at the moment I'd like to see the US taking much more of a lead in the process of dealing with climate change.
/. and elsewhere that the problem is in the hands of not only the US administration but also the US citizens who need to all grow up, face their responsibilites and the damage they are responsible for and begin to put things right.
It is after all them who have benefitted most and contributed most to global warming in order to build up their industries and economy.
Other, not so advanced countries, such as China and India are still developing and shouldn't need to be as active in reducing greenhouse gases as the US should.
Whoever takes the lead in developing the new technologies and processes required to in this new environment will gain an invaluable lead when the rest of the world goes through the same process.
It seems to me, from comments posted on
You know, Michigan's upper peninsula. "Normally" we get about 200" of snow in a winter season. So far this season we've had one major snow storm, leaving us with approximiately 18". That's all. In December 2005, 77.5" fell. I would be surprised if we got a 1/10 of that in 2006.
This slashdot-related signature is a stub. You can help kihjin by expanding it.
If it wasnt for Global Dimming http://en.wikipedia.org/wiki/Global_dimming this would be worse. However, since particulate pollution is being cut more than C02 global dimming is falling behind global warming.
Could this really be avoided? Is it still time to revert those climate changes?
Shouldn't we be preparing for the worse yet?
Instead of deciding whether or not it's really happening ?
I just watched "An inconvenient truth" yesterday. It was the creepiest film I ever watched, way scarier then "The Shining" or "The Ring". I hope most of you out there, have seen it already... I the film Al Gore shows multiple graphs illustrating the drastic changes in the climate - due to our smoking and scorching of Earth - in the last few decades. 2005 was the warmest year, now 2006 bits that questionable record. Are we all running towards the flames of self-destruction? I would say we are all to blame here - It's true, we can all contribute something to the cause. Drive less, own less - endorse global warming awareness in our community. But that will solve a fraction of the problem - America has to wake the hell up and say no to all those fat corporations and say (in the words of the great wizard) "You Shall Not Pass". I mean - we have the technology to turn into cars and motors running on alternative types of energies - we had that technology more than 20 years. Why is the fat fuck the suit - always louder than the suffering masses? Voice out people - let's start our own revolution here - make our children proud of this spineless generation.

Not for me: 2006 UK Temperatures or for some time 1998 Temps
There may be a trend there.......
Unfortunately I couldn't find the wind speed data for this year but that seems to be significantly higher than usual.
Hmmmmmm
In the Victorian Alps (south eastern Australia) the ski season was a dismal flop due to lack of snow. Due to the drought there wasn't enough water for snow making either. But on Christmas day (which is summer here of course), there was a large snow storm up in the mountains: more snow than there was during winter. My entirely unscientific impression of the recent weather is not just that it's getting hotter - it's getting weirder.
Think about it...Hot Eskimo chicks in BIKINIS!!! Just give it ten years.
That's quite a strawman you've got there.
and there are loads.... okay one... decent scientist who says it isn't Man made or true or nothingExactly correct. Everyone knows that the present of a specific scientific principle is decided by a central committee and then approved by the electorate at large. It's an excellent system, look how the Catholic church managed to keep us at the centre of universe!
Well said, refreshing to read that.
/.er to see past the techno-fix as this is the general mindset here.
I just read in 'Revenge of Gaia' that this period of warming may take 100,000 years to subside. R'uh-oh.
A critical fact in Al Gore's film: after compiling the results of 1,100 serious scientific papers about GW not one suggests that it is anything but man's fault. The percentage of journalistic articles suggesting that it may not be man's fault: 53%.
That's where this argument stems from I think. That and big oil sponsored research. Additionally It's very hard for a

Temperature in the UK has apparently been tracked for 350 years and last year had the highest average temperature of those 350 years.
Quoting from http://www.junkscience.com/ on this article:
"s it happens we're just reformatting the thermometer graphic to give people a better idea of global mean temperatures and trends. Using a thousand less-urbanized sites from the METAR database suggests the last year (calendar date to calendar date, in this case) was about as near average as can be expected, within a tenth of a degree of the calculated mean without any enhanced greenhouse forcing.
Is the world really hot and getting hotter? That's a very good question but one to which no one has a good answer. The urbanized record is a little warm but that doesn't mean very much. The planet? Well, that's an open question as yet."
Dammy
This just shows that people don'r really understand what global warming means. Sure, temperatures are going to be one or two degrees higher ON AVERAGE, but that does not mean warmer winters and hotter summers in general. It means that the system as a whole will have more energy, so weather phenomena will be more intensive and fluctuations will have higer amplitude. Think of more powerful storms, more destructive hurricanes, etc. Cold winter 2005 and warmest year 2006 is a nice example of such fluctuation.
I wonder why people start to worry about our environment now, when even 20 years ago it was obvious that something like that will happen.
But now, when it begins to get really expensive (think about damages caused by hurricanes, floodings etc.), people start to care. Before that, the attitude was "Uhh, greenhouse effect? Doesn't concern me, as long as I can live like I used to."
It's almost too late..
i want to remark that we have better technology now, so China needn't pollute as much as we did, and go straight to windpower/solarpower instead of using coal.
Yes, I'm left. You have a problem with that?
The way that the warming effect manifests itself is in the spread of the regions, that is. towards the equator we have an hot arrid region, at the poles we have cold frosty regions and inbetween we have somewhat of a gradient in temperature but also the crucible of interaction between the two. This is how weather is "made": in the interaction between the hot and cold air and water of the equator (solar heated) and poles
Heat up the planet and the hot,dry band around the equator expands, initially the temperate zone is squashed, concentrating the effects of the cold/hot interaction and producing the "extreme" weather we are seeing.
Which is how a globally hotter climate can cause colder weather events in temperate areas.
basically the hotter the global temperature the steeper the gradient of temperature increase is from the poles. the poles themselves recieve little to no solar heating so will continue to sit there stubbornly trying to remain icy cold. steeper temperature gradient = wilder weather with greater extremes
If you don't risk failure you don't risk success.
Firstly the hurricanes were dwarfed by the El Nino effect. This wasn't known at the time the predictions were made. As for the question about the deep freezes that's a misunderstanding. Global Warming is a misnomer, a more accurate name would be Global Climate Change. On average the earth is warmer, however in the short term you are going to end up with more extreme weather. You will end up with places that deep freeze, other places that face rather sudden flash floods, as well as extreme winds and drought. On average there will be less rain fall, but when the rain falls it should be extreme and sudden.
You can expect deep freezes and heat waves, no snow and blizzards. On average it will be warmer and dryer, but you can pretty much get anything day to day.
It is no longer uncommon to be uncommon.
What amuses/terrifies me is the people that argue that global warming isn't humanity's fault, and as such we don't have to do anything about it. I mean, the apocalypse may be coming, but if we didn't cause it, no point in us trying to stop it *shakes head quietly*
Any proposed solution that involves hurting the economies of the nations with resources to actually deal with the problem is not the answer.
Whilst it would be desirable to have a solution to climate change that does not involve hurting the economy (and I believe this is certainly possible), we should get our priorities straight. I would not want a bigger television at the expense of living in a filthy polluted desert.
Nah.
The first thing I thought when I saw those charts was 'correlation doesn't equal causation'.
You're joking right? Correlation does not *necessarily* imply causation but it gives you the right to be damned suspicious that it does. And this is a very good correlation, with a known scientific model that points to causation.
Speaking of strawmen, never mind that the lack of observable stellar parallax made stationary earth models scientifically more tenable. See the discussion of Tycho's observations here: http://csep10.phys.utk.edu/astr161/lect/history/b
Personally, I never subscribe to the "we can't possibly understand it" argument. That also explains my deeply atheistic beliefs.

Be yourself no matter what they say
Exactly. Kyoto would buy our children time to figure out and implement more technologically-advanced, cheaper, and less-painful ways of altering their world.
Coincidentally, Kyoto has not been ratified by the same country where "lower taxes!," i.e., lower taxes for me and higher taxes for my children, is the one political rallying cry that always works.
Why the party that campaigns on lowering taxes and refusing to ratify Kyoto hates the world's children has yet to be determined.
Despite the fact that this is the warmest year since we've started keeping track, I do believe we are still geologically below the average temperature of the earth overall. I would never argue that we don't contribute to the warming of our current era, but to what extent is and probably always will be pretty inconclusive. We should be careful when we make these comparisons, and realize that even without our help the earth will be both warmer and cooler than it is now at different points in the future. So the penguins and the polar bears were going to be soggy toast eventually anyways, just perhaps not so soon. Besides there are plenty of other reasons to want to do something about our pollution problem. For example I just read on bbc news that there were 3600 deaths attributed to smog in Iran just last October. The problem with the Global Warming band wagon is that its hard to quantify, but who can deny air quality problems in urban settings. It seems to me that perhaps Global Warming is over emphasized in comparison to things it might be relatively easier to get people to care about. People are generally short sighted, and pretty much only care about what is right in front of them right now, not whats going to happen in 2040. Trying to get a signifigant portion of the earth's population to change their ways is probably a lost cause no matter how you present it, and the looming spectre of global warming definitely won't be signifigant enough in the herds mind until its way way to late. The problem should be attacked from a different angle. Thats my $0.02 anyways.
Global warming is making everything hotter, ice is melting, seas are rising. We're all in deep doodo. Now, back in the 80's we were all panicking about Nuclear Winters which would freeze us all in the case of a nuclear war (as if the radiation and big holes in the ground weren't enough hassle).
I notice in the news that Israel is thought to be preparing a nuclear strike on Irans nuclear facilities with Neutron bombs. That ought to kick of a nuclear war quite nicely so we're all saved!
Well, it sort of makes sense...
I want a list of atrocities done in your name - Recoil
So the choice is:
1. Try. Make the environment cleaner in the process and more friendly to other species. Develop technologies that will also help human survive the hotter environment as a side effect.
2. Don't try. Either hope maybe - just maybe - it's not happenning at all or that all the effort is useless anyway. Blindly carry on as far as possible without inconvenciencing oneself and either get *really* lucky and all the statistical data was just an error, or die happily as one of the two hundred last humans on the Earth.
Well... I guess it's a question of personal values and philosophy.
(The bottom line is: how does it matter if humans actually were the major cause, and how does it make it bad to try to reduce human environmental impact? So if it's 50-50 (very optimistic for you) we still have answer that works great in _both_ cases, so why still argue against it?)
It's not the fall that kills you. It's the sudden stop at the end. -Douglas Adams
Correlation does not prove causation. Yes, this is skeptical, and I am for environmental protection, but I must add that even 118,000 years of data does not even begin to understand the climate of an Earth that is millions of years old. There is no way to truly test global warming as variables cannot be isolated. ------------- What would a longitudinal study to test global warming entail?
You mean the model in which when you heat up water the solubility of CO2 decreases, so warmer temperatures would cause CO2 levels to increase?
Or the one in which CO2 increases cause a greenhouse effect so increasing CO2 levels cause warmer temperatures?
This post has been made with my current understanding of the problem; if a more informed person can correct me wherever I am wrong, I'd be grateful.
Ok. You use the logical fallacy "straw man" twice. "this is the fallacy of refuting a caricatured or extreme version of somebody's argument, rather than the actual argument they've made. Often this fallacy involves putting words into somebody's mouth by saying they've made arguments they haven't actually made"
For instance. You imply that "green eco-activists" say that CFCs are (solely) responsible for the antartic ozone hole. Most of us do NOT say that. We KNOW that ozone degradation occurs naturally. And by the way, ozone is not decayed by lack of sunlight. UV radiation breaks down oxygen molecules, and ozone molecules, so it both creates and destroys ozone. Cold however, accelerates the breakdown.
The problem is that the degradation was accelerated to dangerous levels.
And the same thing is true for global warming. We know climate goes through natural fluctuations. You are again using a strawman when you say the claim is that it has been caused by "the U.S., industry or humanity".
That is not the claim, the claim is that human activity has caused a huge increase in the rate of change.
Being bitter is drinking poison and hoping someone else will die
Not to mention all sorts of fun deceases you are not used to. Warmer weather means some of the insects will migrate carrying fun stuff like malaria or sleeping sickness.
It's going to be real fun trying to survive in a few decades if we don't deal with the problems right now.
A critical fact in Al Gore's film: after compiling the results of 1,100 serious scientific papers about GW not one suggests that it is anything but man's fault. The percentage of journalistic articles suggesting that it may not be man's fault: 53%.
This is an extremely important point. From reading regular articles, many people believe that the scientific community is evenly balanced on the question of whether human activity is causing global warming.
There's a trap in journalism that can cause this. In an effort for scientifically untrained reporters to report "fairly", they may try to get both sides of a story, even if the other side is not scientifically valid. This leads to the disproportionate number that you quoted above.
That said, there are enough reports that news articles and supposedly scientific studies have been influenced by corporations that I can't blame the journalists entirely.
AFAIK the industrial economy of the USA is heavily subsidized by the government, especially the heavy industry, like metallurgic plants.
With such subsidies, industries tend to invest less on their infra-structure, use less than optimal processes, be less productive and pollute more.
I think that the real problem here is that the USA don't want to pay the price that everybody else already payed to be able to compete on the global market. Take for example the metallurgic industry, here at Brazil we have the most competitive, and efficient, plants... yet the Brazilian steel has a hard time to enter into the USA market because of the subsidies.
If anything, investing on more modern equipment, that pollute less and is more efficient, would drive the USA industry forwards and probably increase the number of jobs. But its easier to rely on governments subsidies.

January is the coldest month in Finland. Usually we have had snow cover by November/December. This year, there has been one freak snowstorm in the beginning of November, and right now it's raining outside. No snow cover for two winter months. Not your typical winter in Finland where temperatures in January can be -20 to -30 degrees Centigrade.
Disclaimer: I know weather does not equal climate.
My other SIG is a Sauer.
The pattern I see from those in the denial business is not one of serious honest skepticism, but of cheap shots, hazy generalizations, unsupported assertions, cherry picking research data out of context etc. There is no new facts that they wish to present. They only wish to undermine the facts of human influence on climate change.
To counter information about melting glaciers they will point out that certain parts of Greenland has accumulating glaciers, but they leave out the information that this was predicted as the edges of the glacier melt more rapidly and result in more snowfall inland. The also leave out that there is still a net loss.
Another ridiculous claim was that 1998 was the hottest year and we have not been getting hotter since and therefore climate models are broken (I saw this in a newspaper article in the last few months) It neglects that 1998 had a strong El Nino and thus was somewhat anomalous, and that 2005 was as hot or even hotter than 1998 (depending on data, google hottest year on record) or that 2006 was quite warm and turns out it will now have the record.
Bottom Line: We dump billions of tons of C02 (heat trapping gas) into the atmosphere annually and it is accumulating. How could this not be having an effect? Wishful thinking?
I think we owe to future generations to at least make an effort to slow the damage we are doing.
Higher energy taxes, more renewables, more nuclear plants, higher CAFE standards would be a start. The climate deniers will whine that this might cost the economy $$$, but seriously do you really think it will be that much of a net cost, how about the Trillion dollars spent on misadventures in Iraq? Would it cost more than that?
Consider the trade deficit benefits of importing less oil, the price for oil would probably drop along with this further improving the deficit. Conservation efforts will have offsetting economic benefits. Putting money into locally constructed nuclear or renewables is money kept in country and not sent out to purchase oil from volatile regions.
Until we find Earth 2, we need to treat Earth 1 with a tad more respect.
It's a multipart question, and the people who either have a vested interest in the answer or a political motivation (ie because they enjoy attacking Republicans/Bush, usually forgetting it was Clinton that refused to sign Kyoto...) cheerfully build strawmen to ignore this.
1) is there climate change?
2) is it caused to a significant degree by human activity?
3) is the result of climate warming bad?
4) can the human activity be changed such that the effect is altered, and what is the opportunity cost for doing so?
(each question is followed by an "if yes, then...")
Few people debate 1; as the poster(s) above pointed out, climate has *always* changed, and is changing. It appears to me that only eco-nuts are claiming that climate should somehow be static from here forward (apparently to remain convenient for humans, ironically). Yet eco-nuts nevertheless like to claim that the 'neanderthals' of the Right are constantly denying 'global warming'. No, as a likely member of this cohort, we don't deny the warming we merely deny your nutball hysteria and most of your solutions, swampie.
2 seems likely, although I haven't seen conclusive proof. We're putting a LOT of heat out, as well as large amounts of CO2. So anecdotally it seems credible to me. But the earth is a BIG system. Almost inconceivably big. Larger shifts in CO2 and temp have occurred historically, and just as quickly, long before humans showed up. It's NATURAL for humans to try to correlate events and their own actions - that's how we got dryads, superstition, and arguably, God - but that doesn't mean they are actually connected causally. Further, it's not impossible that something happens for the first time; it doesn't mean that the observer somehow caused it, no matter how politically convenient he'd find it.
3 NOBODY seems to know, although we managed to live quite successfully at lower tech levels and higher temps at regular periods in our history.
And 4 is what's really under argument. Environmentalists stamping their sandal-clad feet and crying that "we have to" is unpersuasive. And a report claiming that global warming is going to cost X is (nearly) meaningless unless it's compared to the Y cost of mitigation.
Environmentalists' arguments are only going to convince the choir until they first acknowledge that their history of 'global prediction' is really quite bad. Have we run out of clean water? Space for landfills? Food? Trees? Oil? No. None of the 'sky is falling' predictions have come true, so pardon me if I am somewhat skeptical of your latest crisis cry.
-Styopa
Is the planet warming at the moment? - we aren't sure
This is just not true. Spreading FUD and lies will sure make people THINK we aren't sure but that doesn't mean that an informed and educated person can be as sure about climat change as they are about the "theories" of physics which we can safely rely on despite being "just a theory".
Is the planet hotter than at any point in the past? - certainly not.
Your arguement is a textbook case of a fallacy of logic called the appeal to tradition, if i remember right. You try to make it seem like the fact that this is not THE HOTTEST it has ever been means that it's not getting any hotter.
Is there anything we can do about it? - this is the biggie.
The only way we won't be able to do anyhting about it is if enough people are stalled with partisan rhetoric about how this is a polical issue that people need to take sides on based about political values. The energy companies managed to exploit the fact that we are a divided country and they simply chose a side to be against (liberals) and they got the other half of the country aon their side becuase of it.

There is no "-1 offended" or "-1 you don't agree with me" mod options for a reason.
Eh, no, sorry, not quite. All that Kyoto buys is more coal-powered plants for third world nations. If anything Kyoto is more likely to harm the environment, and is, in any event, more of a wealth redistribution scheme than it is an environmental management plan.
It's also funny to note that the country which "hates the worlds children" has made bigger strides in combating GHG emissions than several Kyoto signatories.
But hey, who needs facts and logic when you can get all your opinions from the "down with HaliBusHitler" maniacs, eh?
Actually, that is the only thing we have to do: cut back on CO2 emissions - problem solved.
Not true. While that may buy more time it won't reverse the damage that has already occurred.
Time is what keeps everything from happening all at once.
As the AC pointed out, both effects happen and enhance each other. Greenhouse CO2 makes the Earth warmer, which releases more CO2 from the ocean, amplifying the warming trend, which in turn releases even more CO2, in addition to the continuing increases in atmospheric CO2 due to human emissions (under business-as-usual scenarios).
The Earth is 4 Billion years old. This talks about the weather over the last 120 thousand years.
That is 0.003 percent of the age of the Earth.
Maybe they should look a little farther back. Maybe 4 Million years. Of course, if we want to look at the last 1% of the age of the Earth, we would have to look back 40 Million years.
The fact is, the climate over the last 120 thousand years could be the exception and not the rule.
There is no "-1 offended" or "-1 you don't agree with me" mod options for a reason.
Coincidentally, Kyoto has not been ratified by the same country where "lower taxes!," i.e., lower taxes for me and higher taxes for my children, is the one political rallying cry that always works.
Why the party that campaigns on lowering taxes and refusing to ratify Kyoto hates the world's children has yet to be determined.
You seem to be suffering from a rectal-cranial inversion, let me fix that. In 1998 the US Senate(the branch of the US govt. that ratifies treaties) voted 95-0 against the treaty. Now in case you don't know there are only 100 senators in the US senate. So before you go think one party or another voted against the Kyoto treaty, actually it was both. How you managed to achieve rectal-cranial inversion has yet to be determined, but hopefully this little factoid will help reduce its occurance in the future.
This "economy vs environment" debate is full of shit. Ever heard of the term "dysfunctional production"? Let's use an example:
Some company builds a house in a foreign country. Jobs created, lotsa money. good. Then, the weapon industry lobbies another country to go to war with the other foreign country. Lotsa money, lotsa jobs. good. End result? House is destroyed, bombs are consumed, nothing *useful* have been created in the end, but in the balance sheet, everything is positive, GP is raising (and everyone likes it when GP is raising). All it did is to redistribute some capital from the taxpayers to the weapon/housing industries, for a nil end result.
We have to change the way we see economy.
perception is reality
And by "Ever" we mean since the 1860's, which is the limit of accurate records. If you try to estimate temperatures based upon other data (gases in ice core samples, tree rings, etc.), there were years warmer than this one including the medieval period and a time when the arctic circle was tropical, long before SUVs.
Just to address a couple of points in your ill-informed confused rant:
We're putting a LOT of heat out, as well as large amounts of CO2. So anecdotally it seems credible to me.
The amount of heat we produce is negligible. The major concern is the CO2 we are producing which is trapping the sun's heat.
But the earth is a BIG system. Almost inconceivably big. Larger shifts in CO2 and temp have occurred historically, and just as quickly, long before humans showed up.
This is completely wrong. This is, to the best of our ability to measure it, the fastest increase in CO2 levels (and, not conicidentally, temperature) in the history of the Earth.
There seems to be a common theme in arguments against taking action against climate change: Just Making Shit Up.
These comments are my personal opinions and do not necessarily reflect the opinions of the other voices in my head.
But there is no way to do that.
Fifty years ago there was no way to go to the moon, but motivation, research, and yes...money solved that problem.
Time is what keeps everything from happening all at once.
Let's say that instead of climate change, a large meteor was headed for the planet in, say, 2029. Would we argue for twenty years over whether mankind's radio emissions (or whatever) caused the meteor to near the earth or would we try to think up ways of doing something about it?
I personally think that climate change is caused by increased CO2 emissions from human industry because all of the theory supports it, but it honestly doesn't matter. We have a major problem. We can either point fingers endlessly like a bunch of 5 year olds, or we can try to solve it before it becomes a catastrophe.

This is an excellent point, but it cuts both ways. As you've pointed out, the available evidence during the Middle Ages made an Earth-centered universe viable. Thus, it was entirely possible to rigorously follow the scientific method and still conclude we are at the center.
Rigorously scientific, and quite wrong. This is something that's overlooked all too often -- Science can never promise Truth. The best any theory can hope for is to be very well verified. Please don't get me wrong -- the Scientific Method works better than any other method known to us. We can never know with absolute certainty that our conclusions are true, but using any other method is much worse. I'm not advocating that we replace Science with something else; I'm just pointing out that the conclusions are never absolute.
This is something to keep in mind with the current global warming debate. The evidence suggests that human burning of carbon fuels is a big part of the problem. A strong majority of Scientists across multiple disciplines are convinced we need to do something about it. But they could be wrong.
ENSO is the El Nino Southern Oscillation. If you'd like to simulate global warming and El Nino / La Nina cycles yourself you can do some of the experiments discussed in the article. The EdGCM project has wrapped a NASA global climate model (GCM) in a GUI (OS X and Win). You can add CO2 or turn the sun down by a few percent all with a checkbox and a slider. Supercomputers and advanced FORTRAN programmers are no longer necessary to run your own GCM.

The average high temperature for the month was a record 43.3 degrees. The old record was 42.8 degrees in 1953. The coldest high temperature was 24.7 degrees in 1989 and the normal December average high temperature is 36.4 degrees.
[...]
The average low temperature for the month was 25.6 degrees, warm enough to be the 3rd warmest on record. The warmest average low temperature was 27.8 degrees in 1996 followed by 26.8 degrees in 2001. The coldest average low temperature was 3.4 degrees in 1989 and the normal December average low temperature is 18.7 degrees.

The warmest temperature for the month was 61 degrees on the 1st. I'm going to have to move to Canada if I ever want to see a white Christmas again.
It was not globally the warmest year ever.
It may have been, in North America, the warmest year, by a small amount, for a couple hundred years. Its a bit different. We have also the Holcene Warm Period, and the Medieval Warm Period to worry about, before pronouncing last year the warmest ever.
Global warming may or may not be happening, but headlines like this do not help convince anyone.

- Fact: Greenhouse gases cause more sunlight to be converted into heat.
Here is where the discussion usually breaks down into fisticuffs. We do know that this unnatural stress on the environment (global warming) will cause the global climate to change. However, we do NOT know exactly what will happen in response to this stress. In the past, global warming was a gradual process, as flora and fauna produce greenhouse gases naturally at a much reduced rate. This time the stress is acute, and we have no real past historical basis to predict what will happen.
Personally, I'm with the scientists on this one. (That this is most likely a "bad thing".) Earth has a nasty habit of responding with mass extinctions whenever it gets hit with something big and bad. However, there is a slim possibility that the earth will just "get warmer", which is not entirely a bad thing, but would make dwindling fresh water supplies a real cause for war and conflict.
So to sum up, "global warming" will most likely cause "global climate change". However, we don't know what exactly will change, but it's likely it'll be bad for us.
Except that window power and solar power impact the climate directly, instead of indirectly like fosil fuels.... and they take heat out of the climate, which is a lot more dangerous than adding heat.
Yes, but when scientists "across multiple disciplines" are all weighing in on what the right conclusion should be on a question of climate science, that's a pretty good indication that something other than science is going on.
how do they know what the daily temperature was every day since the ice age in every single part of the globe? Aint no way. True its been warmer but I really am getting sick and tired of all these so call experts who claim they know what the exact temperature was years before man even had a way to measure the temperature.
And before someone says it, there is scientific means to estimate the temperature but there still the plus and minus factor thats a part of all estimates.
For years the Right in America tried to argue that there was no global warming. Finally, what was merely overwhelming research showing that there was indeed warming became impossible to argue, so now the Right tries to argue that "OK, there's global warming, but it's not our fault".
People who are trying so hard to pretend that there is no harm at all in fouling our environment can no longer be taken seriously by the rest of us. We're trying to patiently explain to these knuckleheads that there has to be something done to turn around the damage we're doing to the environment, and while we're arguing, nothing is being done. China will soon (maybe a decade) have a bigger economy than ours and how are we supposed to tell them to back off from all the growth so we don't destroy our environment when we can't even get our own act together?
The Right-Wing in America is being used by multinationals to stall on any sort of effort to change things, so for the foreseeable future, it's going to be more of the same. There's just no more time to waste trying to convince people who believe the Earth is 6000 years old and that Jesus is going to come any day now to take them home that we have to act to protect the world for our grandkids.
I mean really: "What about the Martian icecaps?"?? Is that the latest Investors Business Daily meme to try to keep record profits flowing into the coffers of Shell?
You are welcome on my lawn.
"The Southern Hemisphere, in particular, does not seem to be warming noticeably."
I am sitting naked in my spare room in Melbourne Australia, it is about 2:30AM and simply too hot and muggy too sleep, there is the smell of smoke from extreme bushfires that started two months early this year. Tasmania has had to import electricity from the mainland due to a lack of water in their hydro scheme, 62% of our grain harvest (~17,000,000 tons) has been lost,....oh fuck it, it's too hot to argue with an AC ludite.

Trouble is...this isn't just a happy world of cooperating peoples. It is made up of countries in competition for everything! Competition for land...resources...food....economic power. Until there is some kind of one world order (God forbid), this will be the way of things. If something, while good for the world at large, will be detrimental to a country economically, then, it won't be done.
I don't personally see the 1st world countries willingly sacrificing their lifestyle and world position for the 'greater good'.
No one claws their way to the top, just to willingly let go and slide back down, no matter what the cause....

Gasses become less soluble in warmer water. That's why you get bubbles when heating a pot of water even before the water reaches boiling. Those bubbles are O2, N2, and CO2 (among other gases) that were dissolved in the water.
Venus' atmosphere:
Earth's atmosphere:
Mars' atmosphere:
You can't infer any correlation between CO2 and temperature with the limited dataset provided above. From general knowledge we know that electromagnetic (and thermal) fields fall off with an inverse-square of distance, so we can assume that Mars would be receiving less heat input from the sun than Earth, and Venus more.
My point is that there are more factors affecting temperature than the amount of CO2 in the atmosphere.
There might well be factors other than CO2 affecting the temperatures here on Earth, such as: a possible shift in our orbit around the sun; a possible weakening of the Van Allen Radiation Belts (allowing more radiation input); deforestation (trees help to cool things as well as absorb CO2 and product O2); Urban Heat Islands (ok, I don't buy this one myself since satellite measurements do actually show increases in some places away from urbanized areas and cooling over some others); and probably a whole bunch we haven't identified yet.
All we know for certain is that the global average temperature is increasing, but we don't actually know for 100% certain what's causing it. CO2 is just the most-likely suspect at the moment.
And there are far more reputable scientists who are actually doing useful work on the problem instead of whining about it being too hard.
Better data collection, analysis, and collation from many more terrestrial and orbital observers?
Better models and more powerful computers to run them on?
30 years' more historical data and advancement in the state of the art?
I'm not going to go though a point-by-point on the parent comment, but I would like to respond to this assertion. We don't have as much arable land as you might think. There are three things working against us:
1. A lot of what is considered arable land (and activly used as farmland) is irrigated though aquifers. These are non-replenishable in the scale of human life span. Once they are gone, they are gone.
2. The best arable land is also where we want to live. People don't want to live in deserts or on mountaintops. They want to live in nice temparate plains. Farms become villages become towns become cities. Once that apple orchard becomes a Chevy Dealership parking lot it is never going to be used to produce food again.
3. Finally, climate change (irregardless of whether it is man-made or not) is going to shift arable land around; and it is much easier to "desertify" areable land than it is to "reclaim" desert. Good soil comes from a build up of organic waste. A desert that suddenly starts getting rainfall is going to take many years and a lot of hard work and fertilization to become usable farm land.
Waltz, nymph, for quick jigs vex Bud.
First of all the planet can easily sustain a populous double our current size, if people would just use the grey matter known as our brains that we have been greatly blessed with.
Of course we can, we just have to be more efficient and cooperative and/orreduce our quality of living. But, since that isn't happening because people like you revile the concept of cooperation claiming it is opposed to natural selection, expect to be naturally selected and removed from the populace or have your quality of living greatly reduced.
I hear so many of the far leftists say "stop breeding" and such mantra to that effect...
"Leftists? Left and right are artificial political assignations used to oversimplify politics so it can be superficially reported to people with below average IQs. Trying to imply that those assigned to the left end of the spectrum think others should stop breeding is a big stretch. It sounds a lot more like you're looking to vilify a group, out of mental laziness.
Umm, I don't think you are properly using the word "unquestionably." Promiscuity has a strong positive relationship with poverty, low education rates, and adherence to particular religions including catholicism and some protestant sects. Those traits have a negative correlation with members of political groups generally assigned to the "left." I'd say it is more than questionable. Just as a side note, calling groups "hypocritical is meaningful only if you can demonstrate that contradictory actions are those of an individual, or large number of individuals. If half of the people in a town publicly claim guns are evil and half are gun owners the town is not hypocritical.
It will be a very long time before we have discovered all of the species of the ocean, let alone consumed said species.
Perhaps you're misunderstanding the meaning of "sustainable." It means live in such a way that our supplies will not run out in the foreseeable future. If we're gradually reducing the number of species by consuming them, we're not behaving in a sustainable manner.
Again, there are laws of selection that nature lives by, and if left alone all will balance out.
This is a weak cop out. It is simply a denial of responsibility. "Nature" will take care of things. It is true, but the way it takes care of things might be to eliminate our species or kill off large portion in a slow and painful way, like starvation. One of the defining traits of humanity is intelligence. Thus we define goals and then logically address how best to achieve those goals. Depending upon your definitions that may or may not be "natural."
This 'make everyone equal (financially) so they can all have the same lobster dinner' and such mentality...
Wow, way to cram a lot of logical fallacies into a small amount of words. Argument by association is where you assume people that hold one view must hold another (worried about global warming means you must favor extreme socialism) and then you argue against the second point without ever addressing the first point. This is wrong because people don't all hold the same sets of opinions and because even if the second opinion is wrong, it does not mean the first one is.
The "left" is a nebulous assignation. By definition it cannot crete propaganda. More importantly, propaganda requires a deceitful motivation. What is the motivation of marine biologists and fishing organizations around the world to misstate the facts about fishing harvest sizes. How come most of the fish I can now buy in the supermarket was considered to be "junk" 50 years ago and not suitable for people to eat since other types were plentiful and better? Is i
You can't infer any correlation [...] with the limited dataset provided above.
Exactly. So let's fill out the known facts in that situation.
Planetary Fact Sheet
Venus
- CO2 by volume: 96.5% (965,000ppm)
- Surface Pressure: 92 Bars
- Distance from Sun: 108.2 million km
- Average temperature: 464C
Earth- Distance from Sun: 149.6 million km
- Surface Pressure: 1 Bar
- CO2 by volume: 350ppm
- Average temperature: 15C
MarsGiven those facts, it is very easy to come to substantiated conclusions about CO2's effect, as well as solar intensity's effect, on temperature.
My point is that there are more factors affecting temperature than the amount of CO2 in the atmosphere.
Your point was made by ignoring key facts and going "well, gee... what if?"
I would be interested to know how you justify that claim. We do have decent historical carbon dioxide records via ice cores, and temperature proxies, but the high resolution short term data doesn't support your claim at all, and the longer term data which does, at least, provide significant changes in carbon dioxide and temperature are simply of far too poor a resolution to make any claims about "just as quickly": ice core co2 records that cover previous interglacial periods have resolution of around 500 years; moreover they don't show changes in carbon dioxide as large as what we are currently witnessing; records that go further back to periods with significantly higher carbon dioxide levels have resolution that is orders of magnitude worse.
When mankind lived through previous changes in glacial/interglacial change the rate of change was more than likely slower. More significantly the lower technology levels of the time (and, equally importantly, lower populations) likely actually helped: humans were sparsely spread and nomadic - if climate changed then groups ould easily move to new areas. What we face now is a far denser population where any movement of significant percentages of population with have dramatic effects, and significant amounts of investment in fixed non-moile infrastructure. We can't just pick up and move all our farming infrastructure somewhere else at the drop of a hat - any transition would be costly and significant. Ultimately if you want an accounting of costs then ask an economist. The UK government did, and the result is the Stern Review from Nicholas Stern, a world respected economist. By his accounting (and it was an extremely detailed and in depth study - some 700 pages of report) the effects will be detrimental. Expect more such reports from other economists in the near future.
At this point I would again direct you to the Stern Review which is specifically what you ask for: an accounting of the costs of both inaction, and a comparison of those costs with an equally detailed accounting of the costs of mitigation. The results were that, providing mitigation action was taken sooner rather than later, the costs of mitigation efforts would more than repay themselves within 50 years. Indeed, costs of mitigation could amount to around 1% of global GDP if taken now, while inaction was expected to cost between 5% and 20% of global GDP by 2050. And just to reiterate: this was a detailed report from a respected economist (former chief economist for the World Bank), not a bunch of "sandal clad hippies".

That would be an extremely hot opening for an internet forum post.
If only that forum wasn't Slashdot. *sigh*
Interesting. So that brings our data set from .00000327% of the Earth's estimated age all the way up to .00000778%?
All right. Now I'm convinced.
