re: #324 Pythagoras

The cosmic rays that Svensmark is concerned with come from deep space (e.g. from novas). The idea is that the solar flux deflects these cosmic rays (which affect cloud formation). Less solar flux means more low clouds and that may lead to cooling.

There seem to be some real divergences between the expected outcome of Svensmark’s theory and the observable data though. Again, I really am not well versed in this area, however the concerns seem reasonable. What seems to show up in several of these theories is that sometime in the last 40 years the earth started accelerating its warming in a way that defies almost any of the natural models for ‘natural’ warming.
