Must See: Extraordinary Map of Climate Change

This is one of the best demonstrations of climate change I've seen in a while. It vividly shows, as it moves from mostly cool blues in the 19th century to angry splotches of red in the 21st, both short blips in temperature and the much longer overall warming of the planet.

Some people tend to consider a particularly hot or cold day as evidence for or against global warming, which is a mistake. Global warming, as this video clearly demonstrates, is a long-term trend. And the accelerated warming we have experienced over the past 40 years has been, as the chief scientist behind the study says, "remarkable."

It's interesting to note that this map came out of research led by a Berkeley physicist, Richard Muller, who has been a vocal climate skeptic; the research was funded by the climate-skeptic Koch brothers. The evidence Muller compiled was so conclusive that he very publicly reversed his stand on climate change, writing in the Wall Street Journal last week, "Global warming is real. Perhaps our results will help cool this portion of the climate debate."

I urge you to watch this map animation, and pass it on.

I believe the Kochs only funded 1/3 of the Muller study. In the WSJarticle that you refer to, the last paragraph has Dr. Muller stating that his study did not examine the cause of warming. Dr Muller at a climate conference this week made it clear (youtube video) that there are many uncertainties in human contribution to climate change. He also on video denies he ever suggested that know one should be a skeptic anymore and that skepticism is valid.

That is an excellent demonstration of global climate change. Of course it is evidence of climate change only, it is not evidence that co2 is the cause.
