Obama has four years to save the world

Forget that nagging economic crisis, or niche issues like, say, health care or the war in Afghanistan. A high-profile NASA scientist says Barack Obama has only four years to take the lead on combating climate change and save the earth. Jim Hansen, head of the Goddard Institute of Space Studies, is among a group of respected scientists who argue global warming’s effects - especially rising sea levels - are accelerating faster than was expected, and will lead to more catastrophic results by the end of the century.
