If this is correct, as seems to be the case, then exactly how do we focused upon this aspect of global warming? We can reduce all of the CO2 emissions that we want, but if solar activity causes additional evaporation of water, we're literally p*ssing up a rope.

It's something that I'm going to have to follow up on.


This has been known for a very long time, and was one of the major objections to the early proposal that CO2 might influence global temps. Early test of IR absorption showed that water seemed to get everything that CO2 would, so adding a little CO2 to the atmosphere would not affect things.

Much later, more detailed testing done at high altitude pressures showed a different picture. CO2 in the upper atmosphere has a significant affect. IIRC, this was figured out 50 years ago or so. Just one of the many puzzles that have been solved along the way.
