Heinrich Svensmark theorized that a period of intense solar activity - such as the Grand Solar Maximum of the latter part of the last century - sweeps away cosmic rays and thus reduces planetary cloud cover. Cloud cover increases the Earth's albedo and thus cools the planet. His theory was that an intense period of solar activity would see a rise in the solar wind and a resulting dearth of clouds, thus warming the planet. Experiments have since proven him correct.

Now CERN reiterates this claim.

From a Cern press release:

"n the latest work, published in Science, researchers built a global model of aerosol formation using CLOUD-measured nucleation rates involving sulphuric acid, ammonia, ions and organic compounds. Although sulphuric acid has long been known to be important for nucleation, the results show for the first time that observed concentrations of particles throughout the atmosphere can be explained only if additional molecules - organic compounds or ammonia - participate in nucleation. The results also show that ionisation of the atmosphere by cosmic rays accounts for nearly one-third of all particles formed, although small changes in cosmic rays over the solar cycle do not affect aerosols enough to influence today’s polluted climate significantly."

End excerpt.

The last part will be used by the Global Warming crowd to dismiss the finding as significant, but notice the actual wording OVER THE SOLAR CYCLE. That is not a discussion of long term changes, but rather changes within a solar cycle itself. In other words, moving from the peak of a given cycle to the ends does not materially effect the overall cloud cover. But changes in the solar cycles can make a difference.

Chalk another one up for "deniar" science!
