China's glaciers in meltdown mode

Terra Daily via AFP: Sharp increases in temperature driven by global warming are melting China's Himalayan glaciers, an impact that threatens habitats, tourism and economic development, says a study released Tuesday. Of 111 weather stations scattered across southwestern China, 77 percent showed significant upticks in temperatures between 1961 and 2008, according to the study, published in a British peer-reviewed journal, Environmental Research Letters.

At the 14 monitoring stations above 4,000 metres (13,123 feet), the jump over this period was 1.73 degrees Celsius (3.11 degrees Fahrenheit), roughly twice the average global increase over the last century. Researchers led by Li Zhongxing of the Chinese Academy of Sciences identified three changes occurring in glaciers that could be caused, at least in part, by this steady warming trend.

Many of the glaciers examined showed a "drastic retreat" as well as large loss of mass, they reported. The Pengqu basin's 999 glaciers, for example, had a combined area loss of 131 square kilometres (51 square miles) over two decades, from 1980 to 2001.

The study also showed that glacial lakes -- fed by runoff from melting ice masses -- had expanded in size. "The implications of these changes are far more serious that simply altering the landscape," the researchers warned...
