Here's part two of the excellent and lengthy three-part New Yorker series on climate change, which notes today that:

A possible consequence of even a four- or five-degree temperature rise—on the low end of projections for doubled CO₂—is that the world will enter a completely new climate regime, one with which modern humans have no prior experience. Meanwhile [...] It is believed that the last time carbon-dioxide levels were in this range was three and a half million years ago. "It's true that we've had higher CO₂ levels before. But, then, of course, we also had dinosaurs."
