According to an article in USA Today, based on a report in Nature, the earth's glaciers and permanent snowfields are losing 390 billion tons of snow and ice each year. Enough to raise seas levels by 22 to 27 mm over the last half century. Glacial melt may be as important to sea level increases as the melting of the Greenland and Arctic ice sheet.
The biggest losses were in Alaska followed by South America and the glaciers of the Arctic. All areas have started losing mass over the last 30 years. A clear sign of global warming. A total of 10.6 trillion tons of snow and ice have been lost since 1960, enough to cover mainland USA in over a meter of water.
