The head of the world's leading physics lab at CERN in Geneva has prohibited scientists from drawing conclusions from a major experiment. The CLOUD ("Cosmics Leaving Outdoor Droplets") experiment studies the role that particles from deep space play in cloud formation. CLOUD uses CERN's proton synchrotron to study the phenomenon.
"I have asked the colleagues to present the results clearly, but not to interpret them," Heuer told veteran science editor Nigel Calder. "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 unusual "gagging order" could have been issued because the results of CLOUD are really, really boring, speculates Calder. Another conclusion is that that the experiment invites a politically unacceptable hypothesis on climate.
The CLOUD experiment builds on earlier experiments by Danish physicist Henrik Svensmark, who demonstrated that cosmic rays provide a seed for clouds. Tiny changes in the earth's cloud cover could account for variations in temperature of several degrees. The amount of Ultra Fine Condensation Nuclei (UFCN) material depends on the quantity of the background drizzle of rays, which varies depending on the strength of the sun's magnetic field and the strength of the Earth's magnetic field.
Speaking at a private event attended by El Reg earlier this year, Svensmark, who is not participating in the CLOUD project, wouldn't comment. He said he thought it was one of four significant factors: man-made factors, volcanoes, a "regime shift" in the mid-'70s, and cosmic rays.
The quantity of cosmic rays therefore has an influence on climate, but this isn't factored into the IPCC's "consensus" science at all.
"CERN has joined a long line of lesser institutions obliged to remain politically correct about the man-made global warming hypothesis. It's OK to enter 'the highly political arena of the climate change debate' provided your results endorse man-made warming, but not if they support Svensmark's heresy that the Sun alters the climate by influencing the cosmic ray influx and cloud formation," observed Calder.
