Since it is somehow fair game to compare holocaust deniers to climate change skeptics.....then it must be said that climate change proponents are only pushing their beliefs to kill poor people in poor countries!
Actually, I do think the proponents recognize it as a chance for more Lebensraum. Where do people like to live? Here's a hint: the population density of places like Canada, Siberia, Alaska, and Antarctica are very low. A five-degree increase in temperature would increase our habitat. T. Rex doesn't know what a glacier is, because they didn't exist in the Mesozoic Era, but I bet he'd agree that it seems like a pretty crummy place to live if he ever saw one.
Global Warming = more habitat range. Yay for Lebensraum!
