Suggest renaming 

This article is (as currently written) really about the prospective effects of global warming on humans, not the general effects of climate change.  An article as broadly titled as this on the "effects of climate change" would have to speak about climate changes generally. These would perforce include historic "effects of climate change" such as the Little Ice Age, the Roman Warming Period, Ice Ages, etc. We could include such historic climate effects here, but given the thrust of the article it would probably be best just to do a renaming.
