Clouds of soot melting glaciers in Himalayas and Tibetan plateau
October 5th, 2009 - 12:07 pm ICT by ANI ( Leave a comment )London, October 5 (ANI): In a new research, scientists in India and China have determined that glaciers in the Himalayas and the Tibetan plateau that feed the river systems of almost half the world’s people are melting faster because of the effects of clouds of soot from diesel fumes and wood fires.
According to a report in the Guardian, the results of the research, to be announced this month in Kashmir, show for the first time that clouds of soot - made up of tiny particles of “black carbon” emitted from old diesel engines and from cooking with wood, crop waste or cow dung - are “unequivocally having an impact on glacial melting” in the Himalayas.
Scientists said that, while the threat of carbon dioxide (CO2) to global warming has been accepted, soot from developing countries is a largely unappreciated cause of rising temperatures.
Once the black carbon lands on glaciers, it absorbs sunlight that would otherwise be reflected by the snow, leading to melting.
“This is a huge problem which we are ignoring,” said Professor Syed Hasnain of the Energy and Resources Institute (Teri) in Delhi.
“We are finding concentrations of black carbon in the Himalayas in what are supposed to be pristine, untouched environments,” he added.
The institute has set up two sensors in the Himalayas, one on the Kholai glacier that sits on the mountain range’s western flank in Kashmir and the other flowing through the eastern reaches in Sikkim.
Glaciers in this region feed most of the major rivers in Asia.
The short-term result of substantial melting is severe flooding downstream.
Hasnain said that India and China produce about a third of the world’s black carbon, and both countries have been slow to act.
“India is the worst. At least in China, the state has moved to measure the problem. In Delhi. no government agency has put any sensors on the ground. Teri is doing it by ourselves,” he said.
Decreasing black carbon emissions should be a relatively cheap way to significantly curb global warming.
Black carbon falls from the atmosphere after just a couple of weeks, and replacing primitive cooking stoves with modern versions that emit far less soot could quickly end the problem.
Controlling traffic in the Himalayan region should help ease the harm done by emissions from diesel engines. (ANI)
