As one study after another has pointed to carbon dioxide and other man-made emissions as the most plausible explanation, the cautious community of science has embraced an idea initially dismissed as far-fetched.

Every major scientific body to examine the evidence has come to the same conclusion: The planet is getting hotter; man is to blame; and it’s going to get worse.

Climate researcher John M. Wallace of the University of Washington, UW research scientist Dr. Amy Snover and Ph.D. candidate in atmospheric sciences Justin Wettstein fielded your questions about global warming in a live Q&A session Tuesday. Thanks to everyone who participated.
