re: #71 nomra
Sorry that’s rubbish. A warmer, wetter (more evaporation), CO2 enriched atmosphere should make it easier to grow food. That’s always been the case in the past.
That makes no sense.
We currently have corn planted somewhere. If the climate changes so that corn can’t be grown there, and the farmer has to completely change what crops he grows, that’s not good.
Certain crops take certain climates. Currently, we’re set up to take advantage of the climate. If it changes, all that infrastructure is lost.
