Wingnut Warming

WINGNUT WARMING....Are the global warming denialists really trying to make hay over the fact that a Y2K bug caused NASA to overestimate the average U.S. temperature by 0.03 degrees in 1998? Yes they are. I guess tinfoil caps will do that to you.

And while we're on the subject of desperate wingnuts, is it just me or is the "global warming is a hoax" crowd making a comeback? My vague impression was that flat-out denialism was big in the 90s, but then slowly morphed into an argument that, sure, warming was real, but there was no real evidence that it was manmade. Then that morphed into, sure, warming is real and it's probably manmade, but policywise there's nothing much we can do about it.

But now it seems like straight-up denialism is back in vogue. Is this true? Or am I just re-noticing it lately?
