> More evaporation means more water vapor... More clouds means more rain.
Are you aware of how supersaturation can be achieved? Or why the water content of air in the Arctic is lower than the Namib desert?
The higher the temperature, the more water can be held in the air without precipitation.
> Fascinating. Good thing the earth isn't a human body.
Oh? Which part of "a lot of life out there is used to fairly constant temperatures and lack any form of thermoregulation" did you not catch? You won't be affected directly by a 5C external change, but other things will.
> When's the last time the temperature was up a few degrees for a long period?
With an open carbon cycle, the question is where will it stop? And in the meantime, there's going to be a mass migration of humanity going on while they move to more fertile areas. And if it doesn't stop, we'll really have problems.
I'll pass.
