Amazing work by Henrik Svensmark

[ajmplanner]

Prof. Svensmark has produced a paper that ties supernovae explosions and their concurrent release of cosmic rays, to climate change and even evolution. This is apparently an extension of his work tieing sunsopot activity to the modulation of cosmic ray impacts on the atmosphere that in turn affect the creation of clouds and subsequently temperatures. If his analysis holds up, this is a blockbuster paper. the paper is here:
