New scientific publication 'Definite link found between cosmic rays and clouds' and thus change #cop16 #cancun 
A statistically robust relationship between short-term changes in the intensity of galactic cosmic rays hitting the Earth and the level of cloud cover in middle latitudes is reported in a paper in the journal Atmospheric Chemistry and Physics. The existence of such a relationship has been the subject of speculation for some time and has led some to argue that cosmic rays are related to climate change.
