The world’s greatest snow-capped peaks, which run in a chain from the Himalayas to the Tianshan Mountains on the border of China and Kyrgyzstan, have lost no ice over the last decade, new research shows.
The discovery has (1) scientists, who had believed that around 50 billion tons of melted water were being shed each year and not being replaced by new snowfall.
The study is the first to survey all the world’s icecaps and glaciers and was made(2) by the use of satellite data. Overall, the (3) of melting ice outside the two largest caps —Greenland and Antarctica— is much (4) than previously estimated, with the lack of (5) loss in the Himalayas and the other high(6) of Asia responsible for most of the discrepancy.
Bristol University glaciologist Professor Jonathan Bamber said, “The very unexpected result was the(7) mass loss from high mountains of Asia, which is not (8) different from zero.”
The melting of Himalayan glaciers caused(9) in 2009 when a report from the UN’s Intergovernmental Panel on Climate Change mistakenly stated that they would disappear by 2035, instead of 2350. (10), the scientist who led the new work is clear that while greater uncertainty has been discovered in Asia’s highest mountains, the melting of icecaps and glaciers around the world (11) a serious concern.
“Our results and those of everyone else show we are (12) a huge amount of water into the oceans every year,” said Professor John Wahr of the University of Colorado. His team’s study concludes (13) 443 to 629 billion tons of melted water overall are added to the world’s oceans each year. This is (14) sea level by about 1.5 mm a year, the (15) reports, in addition to the 2 mm a year caused by (16) of the warming ocean.
The scientists are (17) to point out that lower-altitude glaciers in the Asian mountain ranges are (18) melting. Satellite images and reports (19) this. But over the study period from 2003 to 2010, enough ice was added to the peaks to (20).
