Obama looking at cooling air to fight warming (AP)
April 13, 2009 5:36 am | by SETH BORENSTEIN, AP Science Writer Seth Borenstein, Ap Science Writer – Thu Apr 9, 6:17 am ET | Blogs | CommentsTinkering with Earth's climate to chill runaway global warming — a radical idea once dismissed out of hand — is being discussed by the White House as a potential emergency option, the president's new science adviser said Wednesday. That's because global warming is happening so rapidly, John Holdren told The Associated Press in his first interview since being confirmed last month. The concept of using technology to purposely cool the climate is called geoengineering
