Fred - I'm inclined to agree with the evidence as per that graph - what the courts decide is largely irrelevant as far as I'm concerned.
BlueQuinn - Humidity (air moisture) would certainly increase with temperature - but that in itself would not cause temperature drops.
The theory is that increased humidity = more clouds = less radiation reaching the lower atmosphere = lower temperatures (but in combination with other factors such as increasing precipitation, which would be more influential, and other more complex chemical interactions)(however this would also mean a lowering in the production of ozone = more radiation!).
The theory about more CO2 being absorbed by plants and therefore CO2 being self stabilising is a nice theory but also nonsense. Firstly plants, and the ocean, have a finite ability to absorb CO2 - they can only take so much, and that limit is near already.
Secondly, more plant growth through CO2 simply isn't going to happen because of the small matter of deforestation - there is arguably less photosynthetic plant cover on the planet than there ever has been before, so unless people start growing plants instead of building roads, and stop chopping down the forests, CO2 reduction through plants gobbling it up simply isn't going to happen. In theory it could happen but would take many millions of generations of plants to do so, and there would need to be no-one chopping them down.
