Global Warming: Is It True?

Via Climate Progress, a new video by James Powell, Executive Director of the National Physical Science Consortium, which summarizes the evidence for anthropogenic global warming: “everything you wanted to know about climate science under 10 minutes.”

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.


I am away this week on a low-carbon canoe trip in Woodland Caribou Provincial Park. Enjoy the video!
