Well let's see. What could a tipping point bring us to?
Our most recent period of warming that exceeds today's warming trend obviously did not lead to mass extinctions. The Medieval Warm Period, identified by now frozen farms on Greenland's southern coast, far smaller European glaciers, the burgeoning Anasazi/Pueblo culture in what is now unlivable desert, etc. was if anything even cooler than the warm period 7,000 years ago which resulted in the birth of culture in what we call "the Fertile Crescent," but which is now desert.
Tip it back. Pump more moisture into the atmosphere, and who knows, we may soon again see hippos wallowing and giraffes gamboling amongst the vast lakes, swamps and grasslands of the now deserted Sahara.
Certainly there is no valid evidence to counter a very clear archaeological record of lush bounty. There is only unsubstantiated doomsaying.
