It seems to endorse the theory that global warming is related to the amount of solar activity. Last year a Disocvery Channel program theorized that solar activity directly affected cloud formation on earth and this in turn has an impact on earth.The theory was held by a minority of scentists but more of them have converted to this view as more data appears. It is an interesting theory that needs to be studied more.
Water Vapor has much more effect on the mean temperatures than CO2.
Anyone that would like proof, go to any satellite weather page on the internet.
You will notice that they have VISIBLE, INFRA-RED, and WATER VAPOR views from satellite.
Notice they do not have any CO2 views.
