By Lorrie Goldstein ,Toronto Sun Two months ago, James Lovelock, the godfather of global warming, gave a startling interview to msnbc.com in which he acknowledged he had been unduly â€œalarmistâ€ about climate change.
The implications were extraordinary.
Lovelock is a world-renowned scientist and environmentalist whose Gaia theory â€” that the Earth operates as a single, living organism â€” has had a profound impact on the development of global warming theory.
Unlike many â€œenvironmentalists,â€ who have degrees in political science, Lovelock, until his recent retirement at age 92, was a much-honoured working scientist and academic.
His inventions have been used by NASA, among many other scientific organizations.
Lovelockâ€™s invention of the electron capture detector in 1957 first enabled scientists to measure CFCs (chlorofluorocarbons) and other pollutants in the atmosphere, leading, in many ways, to the birth of the modern environmental movement.
Having observed that global temperatures since the turn of the millennium have not gone up in the way computer-based climate models predicted, Lovelock acknowledged, â€œthe problem is we donâ€™t know what the climate is doing. We thought we knew 20 years ago.â€ Now, Lovelock has given a follow-up interview to the UKâ€™s Guardian newspaper in which he delivers more bombshells sure to anger the global green movement, which for years worshipped his Gaia theory and apocalyptic predictions that billions would die from man-made climate change by the end of this century.
Lovelock still believes anthropogenic global warming is occurring and that mankind must lower its greenhouse gas emissions, but says itâ€™s now clear the doomsday predictions, including his own (and Al Goreâ€™s) were incorrect.
He responds to attacks on his revised views by noting that, unlike many climate scientists who fear a loss of government funding if they admit error, as a freelance scientist, heâ€™s never been afraid to revise his theories in the face of new evidence. Indeed, thatâ€™s how science advances.
Among his observations to the Guardian:
(1) A long-time supporter of nuclear power as a way to lower greenhouse gas emissions, which has made him unpopular with environmentalists, Lovelock has now come out in favour of natural gas fracking (which environmentalists also oppose), as a low-polluting alternative to coal.
As Lovelock observes, â€œGas is almost a give-away in the U.S. at the moment. Theyâ€™ve gone for fracking in a big way. This is what makes me very cross with the greens for trying to knock it â€¦ Letâ€™s be pragmatic and sensible and get Britain to switch everything to methane. We should be going mad on it.â€ (Kandeh Yumkella, co-head of a major United Nations program on sustainable energy, made similar arguments last week at a UN environmental conference in Rio de Janeiro, advocating the development of conventional and unconventional natural gas resources as a way to reduce deforestation and save millions of lives in the Third World.)
(2) Lovelock blasted greens for treating global warming like a religion.
â€œIt just so happens that the green religion is now taking over from the Christian religion,â€ Lovelock observed. â€œI donâ€™t think people have noticed that, but itâ€™s got all the sort of terms that religions use â€¦ The greens use guilt. That just shows how religious greens are. You canâ€™t win people round by saying they are guilty for putting (carbon dioxide) in the air.â€
(3) Lovelock mocks the idea modern economies can be powered by wind turbines.
As he puts it, â€œso-called â€˜sustainable developmentâ€™ â€¦ is meaningless drivel â€¦ We rushed into renewable energy without any thought. The schemes are largely hopelessly inefficient and unpleasant. I personally canâ€™t stand windmills at any price.â€
(4) Finally, about claims â€œthe science is settledâ€ on global warming: â€œOne thing that being a scientist has taught me is that you can never be certain about anything. You never know the truth. You can only approach it and hope to get a bit nearer to it each time. You iterate towards the truth. You donâ€™t know it.â€ http://www.torontosun.com/2012/06/22/green-drivel
