Svensmark and his physicist son set up a mini experiment in a basement of the Danish National Space Center in 2005, which found the physical causal mechanism by which cosmic rays facilitate the production of low clouds. When this is confirmed by the CERN CLOUD experiment, the final nail in the coffin of the CO2 theory of climate change will be in place. The sun and the stars will have been shown to control our climate and not the puny self-important inhabitants of planet Earth of current CO2 orthodoxy.
