reporting that what was once considered fringe is being put on the table for examination.
WASHINGTON — It's time to study and maybe even test the idea of cooling the Earth by injecting sulfur pollution high in the air to reflect the sun's heat, a first-of-its-kind federal science report said Tuesday.

In a nuanced, two-volume report, the National Academy of Sciences said that the concept should not be acted upon immediately because it is too risky, but it should be studied and perhaps tested outdoors in small projects. It could be a relatively cheap, effective and quick way to cool the planet by mimicking the natural effects on climate of large volcanic eruptions, but scientists concede there could be dramatic and dangerous side effects that they don't know about. Because warming has worsened and some countries might act unilaterally, scientists said research is needed to calculate the consequences.
Panel chairwoman Marcia McNutt, editor of the journal Science and former director of the U.S. Geological Survey, said in an interview that the public should read this report "and say, 'This is downright scary.' And they should say, 'If this is our Hail Mary, what a scary, scary place we are in.'"
You do know that a global treaty is necessary but
won't be enough to get us out of crisis. I agree with
Joe Romm "Not putting CO2 in the air is much less risky and vastly cheaper than trying to pull it out later. So, let’s try that!" We need to get our green act together. All of us.
