In its yearly report on glaciers, the Austrian Alpenverein, or Alpine Club, documents the melting of glaciers in the Alps. In the winter of 2005 and 2006, the length of 97 glaciers out of the 105 observed was reduced. [Patzelt, 4/2/2007, pp. 20-25 pdf file]

2006: Tibetan Glaciers Melting Fast

The Chinese Academy of Sciences reports that Tibet’s glaciers are melting at an increasingly quick pace and will decrease in size by 50 percent every decade. Over the last 20 years, the country’s average temperature has increased by 2 degrees Fahrenheit. The plateau’s 46,298 glaciers, which cover almost 60,000 square miles, provide water to 300 million people in China alone. According to the academy, the melting of the glaciers will result in an “ecological catastrophe.” The region will suffer more droughts and sandstorms and the tundra will turn into a desert. Many of the world’s largest rivers will be devastated. “The melting glaciers will ultimately trigger more droughts, expand desertification and increase sand storms,” says Dong Guangrong, a spokesperson for the academy.

A study published in the Proceedings of the National Academy of Sciences (PNAS) argues that “the present warming and associated glacier retreat are unprecedented in some areas for at least 5,200 years.” As evidence, it notes the widespread melting of mountain glaciers, the uncovering of plants that were buried thousands of years ago, and a change in the chemical isotopes of ice cores taken from seven mountain glaciers over the past 30 years, including the Huascaran and Quelccaya ice caps in Peru, the Sajama ice cap in Bolivia, and the Dunde and Puruogangri ice caps in China. According to the study’s authors, the ice samples also indicate that there was a sudden cooling of the climate five millennia ago. [Independent, 6/27/2006] Additional evidence of the sudden climate change has come from Mount Kilimanjaro; African lakes; Greenland and Antarctic ice cores, lead author Lonnie Thompson notes in an interview with the Washington Post. “There are thresholds in the system,” he says. “There is the risk of changing the world as we know it to some form in which a lot of people on the planet will be put at risk.” [Washington Post, 6/27/2006]
