You're one of my favorite HN regulars but...<p>It's not "trust us, we're scientists", it's "trust us, we've published extensive peer-reviewed evidence backing up what we're saying, so if you don't believe us you can pick an informed argument".<p>Nuclear winter is one of the more testable scenarios in global climate, since we have small-scale approximations whenever a big volcano erupts. There's been some good recent research at <a href="http://www.agu.org/pubs/crossref/2007/2006JD008235.shtml" rel="nofollow">http://www.agu.org/pubs/crossref/2007/2006JD008235.shtml</a><p>I am not a climate scientist, but I've been driven crazy enough by people's vague arguments to track down foundational papers around some of these issues. Please, all I want is some decent research links for any skeptical stuff, no more cheap shots.
