I beleive he's just a guy who wants to prove his point. I mean come on, you have to realise that neither global warming will kill 2,000. Not just right now I mean. And even though many people were killed by both heat and cold its not likely to increase largely. I think that this whole argument is pointless. He only shows one side of the story because this probably began from another argument. This argument would be pointless if you ask me. The answer is that both heat and cold will kill us. One or the other. (But then again no one did really ask me so...)
