James Powell, Executive Director, National Physical Science Consortium, has produced an excellent YouTube video summarizing the evidence for anthropogenic global warming

Powell is a former college and museum president. “President Reagan and later, President George H. W. Bush, both appointed Powell to the National Science Board, where he served for 12 years.”

Great for sending to any sceptics you may know:


Powell brings together a tremendous amount of the best figures showing the huge amount of data regarding climate change, all of it demonstrating a warmer world, one caused by humans.

He also makes the point that for this not to be the case, there must be several completely unknown processes that overturn the completely known processes that explain the data. There is just too much data from too many different places. It can not easily be simply denied. Believing in things for which there is no physical proof seems to be how many people approach climate change.

Denying the facts in order to foster make-believe will only result in a society which is completely unable to deal with the coming changes.
