CERN: Global Warming Caused by Sun

By Jon E. Dougherty at 30 Aug 2011

(Newsroom America) -- A group of European scientists say new research shows that the sun is the primary driver of climate change, not man-made activities.

The research, conducted by scientists at Geneva-based CERN, one of the world's leading physics labs, and published in Nature magazine this week, stems from the construction of a chamber, called the CLOUD Project, which recreated the earth's atmosphere, the Telegraph newspaper reported.

Scientists were able to demonstrate that cosmic rays can form molecules that then grow seed clouds inside the atmosphere.

"Because the sun’s magnetic field controls how many cosmic rays reach Earth’s atmosphere (the stronger the sun’s magnetic field, the more it shields Earth from incoming cosmic rays from space), the sun determines the temperature on Earth," the paper reported, summarizing the research.

Director General of CERN, Rolf-Dieter Heuer, downplayed the results, however, in an interview with German newspaper Die Welt.

"I have asked the colleagues to present the results clearly, but not to interpret them," he said. "That would go immediately into the highly political arena of the climate change debate. One has to make clear that cosmic radiation is only one of many parameters."

The CLOUD experiment builds upon earlier research conducted by Danish physicist Henrik Svensmark, who demonstrated that cosmic rays provide a seed for clouds, The Register reported.
