Scientist: Forget Global Warming, Prepare for New Ice Age Wednesday, April 23, 2008 Sunspot activity has not resumed up after hitting an 11-year low in March last year, raising fears that — far from warming — the globe is about to return to an Ice Age, says an Australian-American scientist. Physicist Phil Chapman, the first native-born Australian to become an astronaut with NASA [he became an American citizen to join up, though he never went into space], said pictures from the U.S. Solar and Heliospheric Observatory (SOHO) showed no spots on the sun. He said the world cooled quickly between January last year and January this year, by about 0.7 degrees Centigrade. "This is the fastest temperature change in the instrumental record, and it puts us back to where we were in 1930," Chapman wrote in The Australian Wednesday. "If the temperature does not soon recover, we will have to conclude that global warming is over." A sunspot is a region on the sun that is cooler than the rest and appears dark. An alternative theory of global warming is that a strong solar magnetic field, when there is plenty of sunspot activity, protects the Earth from cosmic rays, cutting cloud formation, but that when the field is weak — during low sunspot activity — the rays can penetrate into the lower atmosphere and cloud cover increases, cooling the surface. But scientists from the U.S. National Centre for Atmospheric Research in Bolder, Colorado published a report in 2006 that showed the sun had a negligible effect on climate change. The researchers wrote in the journal Nature that the sun's brightness varied by only 0.07 percent over 11-year sunspot cycles, and that that was far too little to account for the rise in temperatures since the Industrial Revolution. Chapman proposes preventive, or delaying, moves to slow the cooling, such as bulldozing Siberian and Canadian snow to make it dirty and less reflective. "My guess is that the odds are now at least 50:50 that we will see significant cooling rather than warming in coming decades," he writes. foxnews.com
