Of course they did, but this does not debunk global climate change. Only the real wingnuts dispute that global temperatures are rising-they clearly are-and rising with great impact upon coastlines and eco-systems. More reasoned people argue that it is rising but it is not human-caused. But I tend to trust national climatologists who resoundingly suggest that there is a 90% probability the rise is human caused. I trust the climatologists at our excellent universities and the universities of the world more than I trust Senator Imhofe and Michelle Malkin. Even if the rise is not human-caused-because of the potential estimates of damages in the billions, isn't it worth acting on?
