Just FYI, on Wednesday's (3/22) NPR show "Fresh Air" there was a scientist who used to come down on the side of Global Warming is bunk, until he started to research it.
An interesting show for anyone who cares to listen, One of the more interesting points he made that surprised me, was that in the weeks following 9/11 when there was no air traffic over the U-S, the temperature in key cities actually dropped and it plays a role in Global Warming! Why?
I'm sure it's archived.
