The next climate debate bombshell
By Dennis T. Avery
Get ready for the next big bombshell in the man-made warming debate. The world's most sophisticated particle study laboratory -- CERN in Geneva -- will soon announce that more cosmic rays do, indeed, create more clouds in earth's atmosphere. More cosmic rays mean a cooler planet. Thus, the solar source of the earth's long, moderate 1,500-year climate cycle will finally be explained.
Cosmic rays and solar winds are interesting phenomena -- but they are vastly more relevant when an undocumented theory is threatening to quadruple society's energy costs. The IPCC wants $10 gasoline, and "soaring" electric bills to reduce earth's temperatures by an amount too tiny to measure with most thermometers.
In 2007, when Fred Singer and I published Unstoppable Global Warming Every 1,500 Years, we weren't terribly concerned with cosmic rays. We knew the natural, moderate warming/cooling cycle was real, from the evidence in ice cores, seabed sediments, fossil pollen and cave stalagmites. The cycle was the big factor that belied the man-made warming hysteria of the Intergovernmental Panel on Climate Change.
When Willi Dansgaard and Hans Oeschger discovered the 1,500 year cycle in the Greenland ice cores in 1984, they knew immediately that it was solar-powered. They'd seen exactly the same cycle in the carbon 14 molecules in trees, and in the beryllium 10 molecules in ice cores. Both sets of molecules are formed when cosmic rays strike our atmosphere. The cycle had produced a whole series of dramatic, abrupt Medieval-Warming-to-Little-Ice-Age climate changes.
The IPCC, for its part, announced that the sun could not be the forcing factor in any major climate change because the solar irradiation was too small. IPCC did not, however, add up the other solar variations that could amplify the solar irradiation. Nor had the IPCC programmed its famed computer models with the knowledge of the Medieval Warming (950–1200 AD), the Roman Warming (200 BC–600 AD), or the big Holocene Warmings centered on 6,000 and 8,000 BC.
The IPCC apparently wanted to dismiss the sun as a climate factor -- to leave room for a CO2 factor that has only a 22 percent correlation with our past thermometer record. Correlation is not causation -- but the lack of CO2 correlation is deadly to the IPCC theory.
Svensmark noted the gigantic "solar wind" that expands when the sun is active -- and thus blocks many of the cosmic rays that would otherwise hit the earth's atmosphere. When the sun weakens, the solar wind shrinks. Recently, the U.S. Solar Observatory reported a very long period of "quiet sun" and predicted 30 years of cooling.
Last year, Denmark's University of Aarhus did another experiment with a particle accelerator that fully confirmed the Svensmark hypothesis: cosmic rays help to make more clouds and thus could cool the earth.
The CERN experiment is supposed to be the big test of the Svensmark theory. It's a tipoff, then, that CERN's boss, Rolf-Dieter Heuer, has just told the German magazine Die Welt that he has forbidden his researchers to "interpret" the forthcoming test results. In other words, the CERN report will be a stark "just the facts" listing of the findings. Those findings must support Svensmark, or Heuer would never have issued such a stifling order on a major experiment.
