Global Warming: Is humanity screwed?

[Perndog]

I think more than a little money is being wasted, and to be clear, I don't think human activity is an important factor in climate change, nor do I think that Venus used to be an Earthlike planet that became extremely hot due to the greenhouse effect, and I think that politics within science are pushing people very forcefully to whatever will pull in more money, effective results be damned, especially in this case because it's so well publicized. Mr. Milhouse's point that people used to be worried about global cooling is overlooked way too frequently.

But Preechr has quite a bit more vitriol than I do on this topic, and it sounds like he's got mostly the same opinion. I'm really not concerned, and I don't care to argue about it.
