1) The number of cosmic rays impacting the Earth has not changed significantly over the time period when we have seen the fastest increase in global warming.

2) Cosmic rays are absorbed higher in the atmosphere than where clouds usually form. There is not much moisture up there to condense into clouds.

3) CRs produce a lot of charged particles which are not large enough by themselves to form condensation centers, so the CR theory postulates that they merge but have you ever tried to force two magnets together with the same polarity (hard, isnt it?)

4) Lastly, there are two schools of thought as to whether high thin clouds will help heat the planet (by trapping more heat) or cool it by reflecting more sunlight back out into space.

Svensmark says this is "a new theory" but to my knowledge it has been pushing around since the mid 90's in one form or another.

Thanks - ERD50
There is a lot info on the relative roles of the various GHG components in the IPCC FAR report (2007) - one section is dedicated to stratospheric water vapour but it can be fairly dry reading.

There is a pretty nice summary done by the American Geophysical Union at AGU Web Site: Water Vapor in the Climate System. A Special Report.

But when I checked it out some of the figures seemed not to be linked in. However a simple Google on "water vapor" or "hydrological cycle" should get you more information than you ever wanted. Trust most things from NASA, NOAA, and primary science organizations but dont trust blogs, think tanks, or "education sites" from either side of the debate.

Here's a report from the National Academy of Sciences (pdf):

Consult with your own advisor or representative. My thoughts should not be construed as investment advice. Past performance is no guarantee of future results (love that one).......:)
