  1. This video is lying. The Petm (Paeloeocene Thermal Maximum) was not an extinction event. It only resulted in a noticeable extinction of some benthic foraminifera. That was so small an event it doesn't even show up on a marine extinction intensity chart for the Phanerozoic. There was, in fact, a more general flourishing of life at that point, especially terrestrial. So if you're right we've got that to look forward to. The next largest extinction event, since the dinosaurs bit the big one, is the Eocene-Oligocene transition (Grande Coupure). This seems to have been connected with cooling, not warming. Oh dear.
