Global Warming 'Undeniable,' Report Says 1657
BergZ writes "Scientists from around the world are providing even more evidence of global warming. 'A comprehensive review of key climate indicators confirms the world is warming and the past decade was the warmest on record,' the annual State of the Climate report declares. Compiled by more than 300 scientists from 48 countries, including Canada, the report from the National Oceanic and Atmospheric Administration said its analysis of 10 indicators that are 'clearly and directly related to surface temperatures, all tell the same story: Global warming is undeniable.'"

So far, it's been a scorcher for folks all around the world. So it might come as no surprise that the National Oceanic and Atmospheric Administration has released a report revealing 2010 having the record for warmest June, warmest April to June and warmest year to date [noaa.gov]. The announcement [msn.com] said 'Each of the 10 warmest average global temperatures recorded since 1880 have occurred in the last fifteen years. The warmest year-to-date on record, through June, was 1998, and 2010 is warmer so far.' So far we are even surpassing 1998's records which held the warmest year (despite directly contradicting reports [slashdot.org]). It certainly seems the scads of winter precipitation we enjoyed [slashdot.org] were no indication of how we would swelter through our summer this year. Will 2010 turn it around or are we set to break more records?
Aside from that, I'm not really interested in making comments on this anymore because I'm so sick and tired of the armchair idiocy that follows (and somehow gets moderated up). Prediction: Not even 300 scientists from 48 countries and NOAA are going to convince everyone that global warming is real. At this point, I think it's just going to get worse [slashdot.org].

Thats really were the terminology gets muddled. As soon as you use the catch phrase "global warming" you're assumed to be talking about "man made global warming caused by the burning of fossil fuels which has released to many greenhouse gases into the atmosphere." If we could somehow seperate the two, and we can't because (especially in the United States) liberals are ONLY concerned with the man-made "portion" of the effect, the abrasiveness of the discussions would decrease and minds would be more open.

I had an eye-opening experience the other day over at the Oil Drum [theoildrum.com], a blog run by folks associated with the industry. Not people you'd exactly think of as being against the consumption of fossil fuels. But the gist of this posting (which had nothing to do with climate change, and received a lot of favorable commentary) was that we're deeply, deeply fucked if we think we're going to continue burning fossil fuels into our old age. The argument was specifically related to the increasing cost of extraction. (In a nutshell, there's a reason we're now getting our oil from wells a mile underwater).
Now, the conclusion of that poster was pretty depressing, though I don't think he covered all of the options. But what struck me is that if you believe his arguments, it doesn't really matter whether you believe that humans are causing global warming. The actions we need to take now to ensure a reasonable standard of living in 40 years are exactly the same actions we need to take in order to deal with the global warming problem. Above all, to place a tax on fossil fuel consumption (and CO2 taxes do this pretty well) as a means to encourage the market to do something reasonable about the problem. The fact that we couldn't even pass the tiny little tax proposed in the recently defeated Waxman-Markey bill tells us something deeply frightening about our chances.
What kills me about the anti-global-warming argument is that its opponents think that it really matters whether AGW exists. It doesn't matter. For either reason we need to dramatically reduce our fossil fuel consumption and develop alternative sources (efficient, cost-effective nuclear, wind, solar, etc._ just to ensure that we and our children have a chance at living a decent life in the future. There's nothing in the universe that guarantees we won't face terrible consequences for our bad decisions, just because we've had a pretty good run for the past few decades.

Personally, I believe GW is real. I'm just not convinced that man is entirely behind it. And to date, I've not read one account which addresses the problem of the most accurate data in the world (US data) being so inaccurate as to be useless. These scientists then take this data to derive information which they then use to prove a conclusion. When sadly, if the conclusion is anything other than our data is invalid, the only thing they've proved is they are extremely poor scientists who don't grasp the very fundimentals of scientific research.
The problem is, the US has tons of sensors all across the US. Many have been in place for extremely long durations. That sounds great until you discover that almost no one validates the location and integrity of the sensor yet continue to blindly accept the data on which all of this research depends. Worse, independent volunteers who do go validate these sensors are horrified at what they find. And yes, they do document their findings with diagrams and pictures. Again, hopefully someone will provide the link to which I refer.
Many times the findings document sensors which were once in a field are now in the middle of a paved parking lot, or literally next to an A/C exhaust for a building, or receiving radiant heat for an endless list of man made factors which absolutely invalidate the sensor's readings. As a result, the readings are verifiable much higher than would otherwise exist. Additionally, the rise attributed to man by GW falls well within the noise provided by these very erroneous readings.
In other words, these "scientists" are finding a signal from known invalid data, which does not rise above its noise level. This type of science is what is universally called, "quackery", and yet that's largely the basis of a vast amounts of GW research. Until credible researches step forward and both, address how they can get valid data from invalid data and two, can come to inescapable conclusions based on invalid research and data, they only continue to dig their quack-hole deeper.
Man may very well be behind GW, but to date, most if not all research supporting a man-made GW conclusion is compete quackery. Address the validity of their data and then they'll have my attention. Until such time, we have every reason to view them as grant-whores and science-for-hire. They are their own worst enemies.

Because recent warming trends coincide with the Industrial Revolution, greens cry "It's obvious the two are connected!" and climate scientists, who have an overwhelmingly self-selected green bias (after all, the field attracts certain kinds of people), have a vested interest in minimizing the Little Ice Age and Mediaeval Warm Period and making the recent warming seem more intense and unprecedented than it actually is. If we pull back and look at a 100,000-year cycle (thanks to ice core data) instead of just the past 1,000 or 2,000 years, we see that current temperatures aren't unsurprising at all and that indeed we're overdue for warmer temperatures (overdue, because for reasonse which we still can't explain temperatures in the Holocene were relatively steady for about 10,000 years at a time when, according to the cyclical ice core temperature graph, they should have risen as they're finally doing now):

That's the one that loses most people, even those willing to assume that current warming is anthropogenic. How can we assume these changes will be bad for mankind--so bad, in fact, that possibly destroying all industrialized civilizations and dragging them back into stagnation through oppressive resource taxes is preferable to using technology to adapt? When larger timescales show such temperatures aren't unusual, where's the justification? While undeniably bad for small island nations which will be submerged, and for some poor and unstable nations which may see more instability as a result of climate change, the already-industrialized world could easily adapt, survive, and prosper. Given that, why should anyone in the already-industrialized world risk economic meltdown and chaos to avert something they can probably adapt to easily?
For some nations, global warming may even be a big plus. While the southwestern U.S. will probably suffer, the farming belt will just shift north and the country at large will continue to prosper. Canada will benefit greatly from more usable farmland. Europe is a toss-up because ocean and air currents which currently heat it are unpredictable, so anything could happen; but no matter what does, they have the economic and industrial power to cope. Wealthy island nations like Japan will find ways to cope and build sea walls and other defenses or adaptations. China will probably see desert shifting, but increased desertification isn't a foregone conclusion especially with their rapidly-expanding industrialization and huge workforce.

Correct me if my back-of-the-envelope estimate here is wrong.
Just looking at some readily-available graphs of recent temperature averages, it looks like there's a change of 0.8 C in somewhere between 100 and 150 years. That's about 0.005 C/yr (using 150 years). (NOAA claims the rate for the past 50 years is 0.013 C/yr.)
The graph you link notes two areas of interest: a time period with 41 kyr cycles and a time period with 100 kyr cycles. The maximum oscillations during the former appear to be about 5-6 C; during the latter, about 8 C. Using 6 C for the shorter cycle and approximating a "cycle" as taking one-half the period (20 kyr and 50 kyr) to vary between the maximum and minimum, I get temperature change rates of 0.0003 C/yr and 0.0002 C/yr. That's a solid order of magnitude lower rate than the effect that is described as "global warming".
It seems very reasonable to estimate that the decidedly natural effect(s) responsible for the periodic temperature change in the graph you link to account for no more the 5-10% of the temperature change referred to as "global warming".

That doesn't mean that it is in our best interests just to watch it happen. Quite the opposite.
Humanity, at anything approaching our current levels of population and technology and energy need, has not gone through a warming period of the magnitude being predicted even in pretty conservative estimates.
The planet will get by just fine, but there will probably be a whole hell of a lot fewer of us humans around. That reduction is not likely to be pretty. Been laid off lately? Yeah, like that, except you're dead.
The advantage of having all this fancy technology is that we have all these great tools and knowledge about trying to slow down what's coming, mitigate it, and try to figure out ways to feed ourselves when the current crops need to be moved further away from the equator to survive.
At some point, we have to say "OK, whether or not we did anything to contribute to this, is there something, anything, we can do to slow it down, even a little bit? And how do we get by when it changes? What hot-weather arid-land foodstuffs should we be learning more about? What new water purification technologies might we need? How do we slow the fouling of what water and land we do have before we start losing it to desert and ocean?"
That time is not after the climate shifts enough to turn significant fractions of our arable farmland into desert, or after the poles have substantially melted and we've lost vast tracts of livable land and the resulting flooding of shoreline structures has massively polluted the new shorelines.
Preferably, instead of waiting for tax breaks and incentives and whatnot, just think about what you can do to reduce your use of energy. Because, if nothing else, energy use turns to heat. Entropy's a bitch that way.
Will personal measures be sufficient to stop it? Absolutely not. Slow it down significantly? No. Slow it even to a small degree? Probably not, but will popping the AC up a few degrees, turning off lights we don't need and sharing a ride (or bussing, or even cycling) to work from time to time really hurt? We need to buy time.

So what?
Climate is not a constant. Never has been, never will be, and the variation has been a whole lot more than 1/5 of a degree. CO2 levels and global average temperatures have been higher and lower at many points in history, and we didn't magically turn into Venus or Mars. There have been times when the icecaps disappeared, and life somehow went on. Sea levels have varied by hundreds of feet, without Americans to blame for, well, everything. There have also been ice ages, and somehow the world didn't end.
So what?
There will be winners as well as losers. Canadians and Russians should be happy, as this will result in much longer growing seasons and more arable lands for them. They will be the breadbaskets of the world. And if this doesn't happen, if we decide that the current climate is decreed to never be allowed to change again, will there be a demand for subsidies for what "might have been"? Lack-of-CO2 credits?
So here's a question. If civilization had arisen 10,000 years earlier, and someone observed how quickly the ice sheets were retreating, would there be a clamor to protect the glaciers that blanketed pretty much everything north of 50 degrees latitude? Would THAT climate change be seen as the Armageddon that the proposed climate change is being presented as? Would rising sea levels lead to a frothing panic about the loss of the Bering land bridge?
So once again, I ask: If the climate is changing, so what? Climate is not a constant, things aren't automatically evil just because it's a human doing it, and I fail to see how this is any different from any other climate change in the four billion year history of everything on Earth.

Especially related to atmospheric phenomena that's known to cool the Earth, but, in the context of global warming, is said to contribute to global warming by warming the Earth. Think cloud cover, but I'll leave it up to you to reread the reports with this in mind.
A lot of modeling is being done as well, which conclusively proves that humans are contributing to global warming. However, as anyone with a computer science background will tell you, modeling is about as good as the assumptions made going into it. Sure, if the modeled result doesn't reflect empirical observations, you know your assumptions are wrong. But, you can't be sure your assumptions are accurate when the model seems to predict correctly. There have been models that assumed the Earth was the center of the universe, and could still predict planet placement in the sky, but they turned out to be not-so-accurate too.
There is a definite correlation between carbon dioxide and global warming, but causation is unknown. This is key. Most modeling is done with the assumption that carbon dioxide assists global warming, and we can go "back in time" to see that correlation between the two. However, it's also possible that there is a natural increase in carbon dioxide as the Earth warms, going back through the ice record corroborates that also. So, there is strong evidence that global warming is man-made as long as we work on the premise that carbon dioxide causes global warming and humans are responsible for that increase in carbon dioxide. But, that's a lot of assumptions to make.
Please don't get me wrong, a lot of the science is very good in this area. However, quite often, assumptions are made and the results sensationalized by the media. There is a lot of soft science out there. For example, the unlabeled graphs in An Inconvenient Truth don't prove anything, and some of the information was blatantly taken out of context. For many people, that movie provides hard evidence for man-made global warming, but it's anything but.
Also consider that the Earth has been a lot warmer than what it is now, and carbon dioxide levels much higher, well before humans were here to blame. Carbon dioxide levels today are higher than any point in the last 15 million years, but the temperatures aren't, nor are they rising at the expected rate--such as if there were a delay between carbon dioxide and temperature, even though the ice record doesn't seem to support such a delay. There is also the possibility that the increase in carbon dioxide is a result of global warming, not the reverse, and that the heating of the oceans releases carbon dioxide into the air (basic chemistry). There are a lot of things (even basic phenomena) that scientists don't understand. This isn't a bash on the scientists by any means, our knowledge is hampered by the fact that we can't test hypotheses very easily, and atmospheric processes are very complex and interdependent. Also, factor in that the argument for man-made global warming is inductive, and therefore can only be proved by eliminating every other possibility. That's quite difficult to do.
The debate on global warming is not settled, except where the public is concerned. Any researcher that comes out against global warming is going to lose their funding very quickly.

Seemingly absurdly simple questions turn out to be chaotic (the coast of Britain to name a famous paper). How long is the coast of Britain ? Depends on your measurement device. Measure with a ruler 1000 km long and it will be seriously shorter than the English claim. Measure with a ruler of 1 cm and it will be seriously longer than the English claim. By varying the ruler's length you can make the coast of Britain any length, but it is impossible to predict what difference a change in ruler length will do to the length of the coast. The motion of the planets (the famous "three body problem"), another chaotic problem.
The consequences of this chaos conept are vehemently dismissed as total crap, even when it's pretty old and well known mathematical theory. The moon could fly away from the earth tomorrow (and while it probably won't happen tomorrow, the chances that it will eventually happen are very good indeed). That's a trivial consequence of the three body problem. Worse : we can't predict when this event will happen (just like we can't predict the motions of comets and meteorites accurate enough to decide if they'll hit earth until they're right on top of us). At best we can hope for a few days' warning. Despite the seeming absurdity one day the papers will announce "the moon left us, tidal currents slowing to a halt", and this will just happen some day, nobody seeing it coming (or at least nobody correctly predicting when it'll happen).

Global cooling:
In the olden days, we used to do things that would release oxides of sulphur (SOx) into the air. Having these in the air creates some nasty side effects, one of the most dramatic of which is acid rain. Another less drastic side effect is that the SOx in the atmosphere reflects the heat from the sun back out into space, with global cooling as a potential consequence.
Due to the serious nature of acid rain, and the comparative ease of not emitting SOx into the atmosphere (a cheap scrubber on your exhaust) legislation to limit the discharge of SOx met little resistance. Thus, we were able to keep the levels of SOx in the atmosphere at a low level.
Small soot particles in the atmosphere may also contribute to global cooling (through global 'dimming') but regulations to reduce this met little resistance, similar to the SOx example.
Global warming, however, is caused by oxides of carbon (COx) which is not simple to remove from an exhaust stream (as it is the major component.) Thus efforts to reduce the amount of COx going into the atmosphere meet significant resistance as it would necessitate a far greater upheaval than either SOx or soot.
