excerpt:
*****
Former astronaut Harrison Schmitt, who walked on the moon and once served New Mexico in the U.S. Senate, doesn?t believe that humans are causing global warming.
[...]
Schmitt also said geological evidence indicates changes in sea level have been going on for thousands of years. He said smaller changes are related to changes in the elevation of land masses ? for example, the Great Lakes are rising because the earth?s crust is rebounding from being depressed by glaciers.
[...]
Schmitt said he?s heartened that the upcoming conference is made up of scientists who haven?t been manipulated by politics.

Of the global warming debate, he said: "It?s one of the few times you?ve seen a sizable portion of scientists who ought to be objective take a political position and it?s coloring their objectivity."

Personally, I'm sure global warming isn't helped by human activity and also that to "stop" climate change would be against Earth's wishes - Earth changes...sometimes faster than other times. I think the more important concern is whether or not the affects are more than humans can deal with and what we can/should do about that...

I think it would be interesting to have a little debate between Dr. Schmitt and Dr. Hansen (http://en.wikipedia.org/wiki/James_Hansen)...
