Earth’s Polar Ice Melting Less Than Thought
Better technology yields better data. The bad news is the extra water from 2003-2010 would fill Lake Erie eight times
Nearly 230 billion tons of ice is melting into the ocean from glaciers, ice caps, and mountaintops annually-which is actually less than previous estimates, according to new research by scientists at the University of Colorado, Boulder.
If the amount of ice lost between 2003 and 2010 covered the United States, the whole country would be under one-and-a-half feet of water, or it’d fill Lake Erie eight times, researchers say. Ocean levels worldwide are rising about six hundredths of an inch per year, according to researcher John Wahr.
While vast quantities of ice melting into the ocean is not exactly good news, Wahr says, according to his team’s estimates, about 30 percent less ice is melting than previously thought. …
The Himalayas and nearby peaks have lost no ice in past 10 years, study shows
Meltwater from Asia’s peaks is much less then previously estimated, but lead scientist says the loss of ice caps and glaciers around the world remains a serious concern The world’s greatest snow-capped peaks, which run in a chain from the Himalayas to Tian Shan on the border of China and Kyrgyzstan, have lost no ice over the last decade, new research shows.
The discovery has stunned scientists, who had believed that around 50bn tonnes of meltwater 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 possible by the use of satellite data. Overall, the contribution of melting ice outside the two largest caps – Greenland and Antarctica – is much less then previously estimated, with the lack of ice loss in the Himalayas and the other high peaks of Asia responsible for most of the discrepancy. …

Will reduced solar activity counteract global warming in the coming decades? That is what outgoing German electric utility executive Fritz Vahrenholt claims in a new book. In an interview with SPIEGEL, he argues that the official United Nations forecasts on the severity of climate change are overstated and supported by weak science. …
