Is there any scientific basis to dispute that climate change is happening?

SHOOT: I'll try to answer this as briefly as I can - No.

clipped from www.newsweek.com Policymakers who deny the threat of climate change cite the research of Richard Lindzen of MIT and other scientists, who question the link between carbon dioxide and global warming—as the last head of NASA, Michael Griffin, also did. As long as there remains this scientific dispute, why should policy makers act? These contrarians are not having much effect. None of the major countries are denying the problem anymore, though in the U.S. these contrarians are still widely heard, and when it comes to passing a bill in Congress they may still be an obstacle.
