Robots Fly Over Antarctica 45
Roland Piquepaille writes "Researchers from the British Antarctic Survey (BAS) have successfully run a series of flights by autonomous unmanned aerial vehicles (UAVs) over Antarctica. These robotic planes have a 2-meter wingspan and weigh 6 kilograms. They are powered by Lithium Ion Polymer (LIPo) battery packs — similar to the ones in your cellphones or laptops. So far, these autonomous UAVs have completed about 20 flights lasting 40 minutes each. These robots can fly over 45 kilometers while taking about 100 measurements per second about the exchange of heat between the lower atmosphere and sea ice. According to one of the scientists, 'the future of atmospheric research will be robotic.'"

Conclusion: the ice is melting. We knew that already.. we even have a good idea of the rate at which it is melting and how fucked we are going to be as a result. Now that we know this, can we please do something about it? Or are we just not ready for that yet? Another 20 years of study perhaps?
But we don't know really the root cause. Sure we are quick to point the blame at cars and factories but also farting cows are to blame perhaps even more then us. So really, we can prove that the ice is melting, what we can't prove is what is to blame. There is no point in going 5 steps backwards only to find out that it really wasn't anything we did.

Problem is, if you don't understand the root cause and the system well enough, you could make things much worse. Ever solve a bug that seemed pretty straightforward only to cause major data corruption later down the line?
This isn't just an analogy. It has only been until recently that we've recognized global dimming as a real phenomenon that we've pretty much undoubtedly caused ourselves from all the particulates we spew into the atmosphere. So let's say that to solve global warming we drastically cut down on air pollution from cars, factories, and power plants. Seems straightforward, right? Well, that cuts down on atmospheric particulates, which increases the amount of solar energy reaching the earth and causes a net INCREASE in temperature.
So it's not entirely Pascal's wager -- we do have something we could lose by being wrong.

Solar energy is trapped in the atmosphere due to the fact the solar rays come in from the sun and start bouncing all over the place, never getting a chance to escape. Cleaner air would allow for more sunlight to hit the earth surface more directly, but it would also allow for more energy to bounce right off back into space without being trapped.

It was a single example of a very complicated system that we clearly don't understand.
Beside, I'm just telling you what I saw on Nova on PBS -- not some right-wing propaganda. The researcher who coined the term global dimming has been researching this for fifty years. With his research and experiments, he came to the conclusion that global dimming, as caused by particulates in the air, currently causes a decrease in temperature. This is bad because it's offsetting global warming caused by greenhouse ga

If reading is too much (there are over 10,000 peer-reviewed papers on the subject), grit your teeth and watch or at least listen to Gore's presentation.

True, but the problem is that China now accounts for the vast majority of pollution. They refuse to use any clean tech to clean up their pollution. It is not just their coal plants that have this issue. It is nearly all of their plants that pollute heavily.
