“Let’s put it this way, if someone told me we could keep CO2 in the range it’s been during the time our civilizations came into being because the climate was conducive to grain plants which allowed us to even have civilization, or we could allow CO2 to go to levels when human ancestors were tree-shrews and the world was covered with steaming jungles and there were no grains at all…I’ll take the range in which our civilization has come into being. Letting CO2 continually rise, is conducting a huge experiment (rather like rolling the dice) on the future of the planet. Last time I checked, we haven’t got a spare in case we bet wrong”

Those would be the same CO2 levels that allowed the formation of glaciers a mile thick over everything north of Virginia for 100,000 years with 10,000 year interglacial periods. The current interglacial began over 10,000 years ago.

The level of ignorance in your blitherings, Gates, never ceases to amaze me.
CO2 at end of ice age right before holocene: 200 ppm
CO2 during interglacials 280 ppm
CO2 during Jurassic, over 2000 ppm
