I've been listening to podcasts on global warming and the future (both Stanford and Oxford universities have excellent lectures on itunes U), a lot of what I'm hearing scares me, but the fact that some really smart people are working on solving some of the earth's problems is comforting. That's not the feeling I get when reading what the skeptics are saying. Richard Dawkins, (speaking about creationism, but I think the analogy travels) compares them to Yappy terriers (I'm not sure the skeptics on global warming is as benign as terriers though) and as I already have an obnoxious terrier at home and seldom consult her when seeking information. I think I'll ignore the skeptics for the time being.
For some examples of how the debate is going check the comments I did get on this post (occasionally rather nasty reading )
