[extropy-chat] The great global warming swindle

[Lee Corbin]

Here is one interesting tid-bit in the sequence of arguments presented:

> When less cosmic radiation reaches Earth, fewer clouds
> form and the full effects of the sun's radiation heats the planet.

Wikipedia suggests

> Cosmic rays have been experimentally determined to be able to produce ultra-small aerosol particles [3] [5], orders of magnitude 
> smaller than cloud condensation nuclei. But the steps from this to modulation of cloud formation and thence to be a contributor of 
> global warming have not been established. The analogy is with the Wilson cloud chamber, however acting on a global scale, where 
> earth's atmosphere acts as the cloud chamber and the cosmic rays catalyze the production of Cloud condensation nuclei. But unlike 
> a cloud chamber, where the air is carefully purified, the real atmosphere always has many CCN naturally. Various proposals have 
> been made for the exact mechanism by which cosmic rays might affect clouds, including Ion Mediated Nucleation, and through an 
> indirect effect on current flow density in the Global electric circuit (see Tinsley 2000, and F. Yu 1999).
