Sunspot activity has not resumed 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. Geophysicist Phil Chapman, the first Australian to become an astronaut with NASA, said pictures from the US Solar and Heliospheric Observatory showed there were currently no spots on the sun.
He said the world cooled quickly between January last year and January this year, by about 0.7C. "This is the fastest temperature change in the instrumental record, and it puts us back to where we were in 1930," Dr Chapman writes in The Australian today. "If the temperature does not soon recover, we will have to conclude that global warming is over."
The Bureau of Meteorology says temperatures in Australia have been warmer than the 1960-90 average since the late 1970s, barring a couple of cooler years, and are now 0.3C higher than the long-term average.
A sunspot is a region on the sun that is cooler than the rest and appears dark. Some scientists believe 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 US National Centre for Atmospheric Research 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 0.07per cent over 11-year sunspot cycles, and that that was far too little to account for the rise in temperatures since the Industrial Revolution.
Dr 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.
His Eminence also says that global warming is over

Canada has just experienced the coldest winter and the heaviest snowfalls since 1970-1, which was called a once in a thousand years event. Another 18 centimetres of snow would set an all time record. A Kingston newspaper had a marvellous cartoon of a tough old Canadian, rugged up against the cold and hacking the ice off the windscreen of his car. The caption read "Global warming my a."!
In China the Chinese New Year coincided with a fierce cold snap and snow storms which prevented many city workers returning to their villages for the celebrations. Police had to deal with the ensuing riots. London has just experienced snow at Easter.
The world is much bigger than both China and Canada combined, which might be the exceptions to the new rule of man-made global warming, but they are inconvenient facts for the climate change bandwagon. And it is an intolerant bandwagon with loud exaggerated claims that the issue is settled and that an unchallenged consensus among scientists confirms the hypothesis of dangerous humanly caused global warming. In fact the issue is far from settled. Politicians sceptical of these claims would need unusual courage to resist the strong tides of public opinion. However the rest of us are not so constrained and we should consider all the available information. Three points are of some significance.
Last December more than 100 prominent international scientists, some of them members of the U.N. Intergovernmental Panel on Climate Change, warned the U.N. that attempting to control the earth's climate was "ultimately futile". So did 500 experts in Manhattan in March. Fighting climate change was distracting governments from helping the most vulnerable citizens adapt to the threat of inevitable natural climate changes, whatever they might prove to be. Futile attempts to prevent global climate change would be a tragic misallocation of resources, they claimed.
Secondly none of the natural changes observed with glaciers, sea-levels and species migration is outside the bounds of known variability, including the warming of 0.1 to 0.2 degrees Celsius per decade in the late twentieth century. But the 1930s decade was warmer than the 1990s. Most importantly the global temperature has not increased since 2001. Global warming has ceased (New Statesman 19/12/2007). This finding invalidates the global warming hypotheses because the amount of carbon dioxide in the atmosphere continues to increase and the temperature should be increasing too. It isn't.
The last point to be acknowledged is that today's computer models cannot predict climate over long periods because there are too many unknowns and variables. We should never forget that while computers are miracles of human ingenuity, able to assimilate extraordinary amounts of information in the briefest time, they are also limited, cannot think for themselves and are totally obedient to their last human master. More than this is needed to predict the future.
