"We need to deal with global warming, not only because it's the right thing to do, it's the smart political and diplomatic thing to do," said Sen. Chuck Hagel, R-Neb.
Hagel has written three bills with Democrats aimed at promoting development of clean technology at home or abroad.

"The only bill that guarantees reductions is the McCain-Lieberman Act," said Fred Krupp, president of the advocacy group Environmental Defense.
