The plague of climate denialism on HN seems to be getting much worse as of late. Why does trash like this keep getting upvoted?
Because stuff like this http://www.timesonline.co.uk/tol/news/environment/article702... is now pouring out, and realclimate.org is implicated in the climategate scandal, so you might want to go somewhere else for unbiased information
By the way, when you refer to "the climategate scandal," you really don't do yourself any favors. There is no "climategate scandal" other than that a well-coordinated group of hackers (in the negative sense of the word) committed criminal acts in order to embarrass scientists and undermine the perceived validity of their work. Indeed, in that sense, "climategate" is much like the Watergate scandal, and you seem to be throwing your lot in with the villains of this story. I'll give you the benefit of the doubt and assume you aren't evil, manipulative or duplicitous, but merely ignorant. There's many good (read, well-cited) sources dedicated to debunking the poisonous myth that is "climategate," such as http://scienceblogs.com/islandofdoubt/2009/12/the_climategat....
