Prominent global warming alarmist has a change of heart

Lawrence Soloman in the Canada’s National Post writes:

Claude Allegre, one of France’s leading socialists and among her most celebrated scientists, was among the first to sound the alarm about the dangers of global warming.

“By burning fossil fuels, man increased the concentration of carbon dioxide in the atmosphere which, for example, has raised the global mean temperature by half a degree in the last century,” Dr. Allegre, a renowned geochemist, wrote 20 years ago in Cles pour la geologie..” Fifteen years ago, Dr. Allegre was among the 1500 prominent scientists who signed “World Scientists’ Warning to Humanity,” a highly publicized letter stressing that global warming’s “potential risks are very great” and demanding a new caring ethic that recognizes the globe’s fragility in order to stave off “spirals of environmental decline, poverty, and unrest, leading to social, economic and environmental collapse.”

In the 1980s and early 1990s, when concern about global warming was in its infancy, little was known about the mechanics of how it could occur, or the consequences that could befall us. Since then, governments throughout the western world and bodies such as the United Nations Intergovernmental Panel on Climate Change have commissioned billions of dollars worth of research by thousands of scientists. With a wealth of data now in, Dr. Allegre has recanted his views. To his surprise, the many climate models and studies failed dismally in establishing a man-made cause of catastrophic global warming. Meanwhile, increasing evidence indicates that most of the warming comes of natural phenomena. Dr. Allegre now sees global warming as over-hyped and an environmental concern of second rank.

His break with what he now sees as environmental cant on climate change came in September, in an article entitled “The Snows of Kilimanjaro” in l’ Express, the French weekly. His article cited evidence that Antarctica is gaining ice and that Kilimanjaro’s retreating snow caps, among other global-warming concerns, come from natural causes. “The cause of this climate change is unknown,” he states matter of factly. There is no basis for saying, as most do, that the “science is settled.”

Dr. Allegre’s skepticism is noteworthy in several respects. For one, he is an exalted member of France’s political establishment, a friend of former Socialist president Lionel Jospin, and, from 1997 to 2000, his minister of education, research and technology, charged with improving the quality of government research through closer co-operation with France’s educational institutions. For another, Dr. Allegre has the highest environmental credentials. The author of early environmental books, he fought successful battles to protect the ozone layer from CFCs and public health from lead pollution. His break with scientific dogma over global warming came at a personal cost: Colleagues in both the governmental and environmental spheres were aghast that he could publicly question the science behind climate change.

In related gw news, the UK’s Channel 4 will be airing a ‘controversial’ documentary on Thursday which reportedly claims that ‘accepted theories’ about so-called ‘man-made gw’ are “lies”:

The Great Global Warming Swindle’ – backed by eminent scientists – is set to rock the accepted consensus that climate change is being driven by humans.

The programme, to be screened on Channel 4 on Thursday March 8, will see a series of respected scientists attack the “propaganda” that they claim is killing the world’s poor.

Even the co-founder of Greenpeace, Patrick Moore, is shown, claiming African countries should be encouraged to burn more CO2.

Nobody in the documentary defends the greenhouse effect theory, as it claims that climate change is natural, has been occurring for years, and ice falling from glaciers is just the spring break-up and as normal as leaves falling in autumn.

A source at Channel 4 said: “It is essentially a polemic and we are expecting it to cause trouble, but this is the controversial programming that Channel 4 is renowned for.”

Controversial director Martin Durkin said: “You can see the problems with the science of global warming, but people just don’t believe you – it’s taken ten years to get this commissioned.

Hmmm. Now I wonder if this gw movie will be nominated for any Oscars next year? :-?
