Harvard climate scientist James G. Anderson interviewed by Dale Lehman.
This week, Anderson lucidly explains why "global warming" is a bad term to use (it understates the problem's breadth and severity). He makes short work of the claim that climate change is natural, not man-made. And he has interesting things to say about the ozone layer ... the Kyoto Protocol ... and why electricity is overwhelmingly the best fuel, not only for transportation but for heating too.
