> Randall chose one of the lowest point every in the history of earth as the "baseline". Randall's graph starts at a little over 4C lower than current temperatures. The most recent minimum on your first graph is 7C below current temperatures. Your 2nd graph couldn't be shown in Randall's format because it would either take too long to scroll, or it wouldn't have the resolution needed to show the dramatically higher rate of change. > The recent rise of temperature is significant, but not unprecedented. The rate of change is unprecedented. > Before we reach a point that one could qualify as a "hot earth", we would need to warm up by an additional 10 to 15 C° Billions will die before that.
