C2, yes, for now we are boosting the CO2 content of the atmosphere, but it's only a small proportion. It's not as though we are trebling the CO2 in the atmosphere. But we are well within historic bounds and well below eons-ago bounds when there was a LOT more stuff in the atmosphere, which is now much thinner. All that limestone used to be alive and the oxygen in the limestone came from the atmosphere. The dolomite mountains of the Alps used to be alive. There is a lot of locked up, frozen and dead carbon and oxygen which belongs in the atmosphere, keeping us warm. Increased solar radiation definitely makes it warmer, unless there is a lot more snow, cloud and desert to reflect the increased sunshine right back out again. There is a lot more desert now than 4000 years ago, when Egypt was lush and Europe was green too. The deserts are near the equator, so do a LOT of reflecting. The trees are hiding nearer the poles where there's less sun. So reflection from land is a lot more than 4000 years ago. We just need to get some decent snowfall and we'll flip into an ice-age. Maybe by Xmas. Earth is burying carbon and oxygen and freezing as a result. Anyway, enough rants from me. Must go. Mqurice
