Liberals try to get their groove back Clouded research LAWRENCE SOLOMON, Financial Post Published: Friday, February 23, 2007 Jasper Kirkby is a superb scientist, but he has been a lousy politician. In 1998, anticipating he'd be leading a path-breaking experiment into the sun's role in global warming, he made the mistake of stating that the sun and cosmic rays "will probably be able to account for somewhere between a half and the whole of the increase in the Earth's temperature that we have seen in the last century." Global warming, he theorized, may be part of a natural cycle in the Earth's temperature. Kirkby was immediately condemned by climate scientists for minimizing the role of human beings in global warming. Kirkby by citing scientists who feared oil-industry lobbyists would use his statements to discredit the greenhouse effect. Kirkby's path-breaking experiment -- seemingly a sure thing when he first announced his proposal-- was put on ice. Kirkby was stunned, and not just because the experiment he was about to run had support within his scientific institute, and was widely expected to have profound significance. Kirkby was also stunned because his institute is CERN, and science performed at CERN had never before seemed so vulnerable to whims of government funders.
CERN, based in Geneva, is the European Organization for Nuclear Research, a 50-yearold institution, originally founded by 12 countries and now counting 20 country-members. It services 6,500 particle physicists -- half of the world's total -- in 500 institutes and universities around the world. And it is home to Jasper Kirkby's long-languished CLOUD project, among the most significant scientific experiments to be proposed in our time. Kirkby's proposal first saw the light of day, the funding is in place and the work has begun in earnest. The CLOUD (Cosmics Leaving OUtdoor Droplets) laboratory experiment, CERN believes, will show the mechanisms through which the sun and cosmic rays can influence the formation of clouds and thus the climate. The CLOUD project will use a high-energy particle beam from an accelerator to closely duplicate cosmic rays found in the atmosphere. This will be the first time this technology will be brought to bear on global warming, the most controversial scientific question of the day. Also for the first time, very basic answers about the drivers of climate change may surface to dispel the general paucity of data on the subject. "By studying the micro-physical processes at work when cosmic rays hit the atmosphere, we can begin to understand more fully the connection between cosmic rays and cloud cover," CERN explains. "Clouds exert a strong influence on the Earth's energy balance, and changes of only a few per cent have an important effect on the climate." Kirkby has assembled a dream team of atmospheric physicists, solar physicists, and cosmic ray and particle physicists from 18 institutes around the world, including the California Institute of Technology and Germany's Max-Planck Institutes, with preliminary data expected to arrive this coming summer. The world of particle physics is awaiting these results with much anticipation because they promise to unlock mysteries that can tell us much about climate change, as well as other phenomena. The world of climate science, in contrast, is all but ignoring the breakthroughs in climate knowledge that CERN is about to reveal.
