Russian academic says CO2 not to blame for global warming
Rising levels of carbon dioxide and other gases emitted through human activities, believed by scientists to trap heat in the Earth's atmosphere, are an effect rather than the cause of global warming, a prominent Russian scientist said Monday.
Habibullo Abdusamatov, head of the space research laboratory at the St. Petersburg-based Pulkovo Observatory, said global warming stems from an increase in the sun's activity. His view contradicts the international scientific consensus that climate change is attributable to the emission of greenhouse gases generated by industrial activities, such as the burning of fossil fuels and deforestation.
“Global warming results not from the emission of greenhouse gases into the atmosphere, but from an unusually high level of solar radiation and a lengthy - almost throughout the last century - growth in its intensity,” Abdusamatov told RIA Novosti in an interview.
“It is no secret that when they go up, temperatures in the world's oceans trigger the emission of large amounts of carbon dioxide into the atmosphere. So the common view that man's industrial activity is a deciding factor in global warming has emerged from a misinterpretation of cause and effect relations.”
The Intergovernmental Panel on Climate Change, a UN panel of thousands of international scientists, widely regarded as an authority on climate change issues, established a consensus many years ago that most of the warming experienced over the last half-century has been attributable to human activities.
However, scientists acknowledge that rises in temperatures can potentially cause massive increases of greenhouse gases due to various natural positive feedback mechanisms, for example the methane released by melting permafrost, ocean algae's reduced capacity to absorb carbon at higher water temperatures, and the carbon released by trees when forests dry up.
Abdusamatov, a doctor of mathematics and physics, is one of a small number of scientists around the world who continue to contest the view of the IPCC, the national science academies of the G8 nations, and other prominent scientific bodies.
He said an examination of ice cores from wells over three kilometers (1.5 miles) deep in Greenland and the Antarctic indicates that the Earth experienced periods of global warming even before the industrial age (which began two hundred years ago).
Another voice in the wilderness. I will look more closely at Kyoto when they make China and India and all of the other exempt 'developing nations' comply as well. That and adding Water Vapor into their model. (H2O is the worst 'greenhouse gas' by a long long shot.)Posted by DaveH at January 19, 2007 09:50 PM | TrackBack
