Thank you. You just supported my hypothesis that current GW will make Earth wetter, not drier. I suspect that increased water cycle will result in bringing rain to the great deserts of the world. Well, that combined with the increased meandering of the jet stream.
So, in 2100, I expect the world to be 2 to 3 degrees Centigrade warmer than today. I expect oceans to be about 5 to 8 ft deeper.
I also expect mankind to have been a bit late in responding to the GW process. Therefor, methane clathrates will have unleashed much of their methane into the atmosphere. The Holocene will be done, and the Anthropocene just beginning to begin. I expect oceans to rise at least 70 ft, to eventually match the levels of the Pliocene, at a minimum.
[Since the Pliocene ocean levels were done with CO2 at about 400ppm, and we have already passed that, probably to reach 700ppm by 2100, PLUS a huge increase in methane, which did not happen during the Pliocene, a complete melting of the polar ice caps is probable, IMO.]
Considering paleoclimatological data, I am surprised that climatologists maintain the idea that the Earth will get drier as the climate warms. That was not the case during the Mesozoic, and I do not see why it should be the case this time.
