This comment from Brian Dodge comes from RealClimate according to the website address. RC writers are defenders of the orthodoxy and have a vested interest in current climate models. Most of their material has been debunked by observational data.

Before you get your knickers in a twist over how The CERN CLOUD experiment strikes a major blow to climate models, you should note that they compared nucleation between zero radiation from the accelerator (and the experiment was shielded from natural cosmic rays) to radiation levels comparable to that from natural GCRs. Natural GCR levels only vary about +-10 percent, and are never zero. You should also note that they found the strongest effect at cooler temperatures, comparable to higher altitudes – and increases in high clouds will have a warming effect, not the cooling effect claimed by Svensmark or Watts. And finally, if you download Oulu cosmic ray data and UAH temperature data (Monthly, from 1980) and plot and compare them, you will find that the cosmic ray numbers fluctuate up and down with the solar cycle, but there isn’t a corresponding cycle in the temperature data; there is, however, a general upward trend in cosmic rays, which weakly corresponds to the upward trend in temperatures – R^2 is +0.274. Real world data shows Svensmark’s conclusions drawn from lab experiments are incorrect.

Hooray for proof of an easily understood mechanism of what is the main driver of climate variation. Meantime I’m investing in some warm clothing.
