The chief of CERN has prohibited its scientists from drawing any conclusions from a major experiment that appears to prove that solar activity and the resulting ebb and flow of cosmic rays has a direct effect on the climate.
First, the results described provide strong evidence that the sun is a much more important component in climate change than any climate model has previously predicted. These results could help explain the Little Ice Age, which took place around 1700 at exactly the same time the sun became very quiet and stopped producing sunspots for decades. They could explain the Medieval Warm Period around 1000 AD, when cosmic ray activity declined (which also suggests the sun become more active) and the earth apparently warmed. And they might very well even explain the recent cooling during the past decade, which also took place during a period of solar inactivity and a comparable increase in cosmic ray activity.
