Combjelly Re..Maybe. Maybe not. When you change the heat balance, you change the weather patterns and likely the ocean currents. This may or may not lead to increased deserts. In addition, you shift the isotemp lines and change the crops that can be grown in particular areas. <<<

All of those things may be true, but they will just change the area and way things are grown; not necessarily how much. For instance, some coastal cities may flood; but a lot of the west may get enough rain to become suitable for crops without massive irrigation. The higher temps, may force some crops up north, but overall higher temps and co2 are likely to grow more crops. Why. Increased heat increases evaporation from the oceans and makes more moisture available. Secondly, more co2 will increase the growth rate of crops in suitable areas. So I expect there would be a net advantage cropwise. In fact, the US has had record crops lately. Part of it may be due to higher temps and higher CO2 levels. We have had record rains also here in Wi. so our crops have been very good. Unless the prevailing jet stream changes, I don't see any major changes in the desert area, but out west, more moisture in the atmosphere, could increase rain.

To give one example, in the Houston area tomato plants don't set fruit during the summer, night time temperatures are too high.

That's interesting...I knew that most varieties needed it to be over 80 F during the day to set fruit but I didn't know cool temps at nite were required. Here in Seattle we have problems with that day time requirement.

BTW I didn't respond to your domino's definition...not something I want to think about too much during these difficult times....but lets leave it that I hope I don't have a domino's moment.
