Glacier Melt Could Signal Faster Rise in Ocean Levels
[...]
The scientists said they do not yet understand the precise mechanism causing glaciers to flow and melt more rapidly, but they said the changes in Greenland were unambiguous -- and accelerating: In 1996, the amount of water produced by melting ice in Greenland was about 90 times the amount consumed by Los Angeles in a year. Last year, the melted ice amounted to 225 times the volume of water that city uses annually.
"We are witnessing enormous changes, and it will take some time before we understand how it happened, although it is clearly a result of warming around the glaciers," said Eric Rignot, a scientist at the California Institute of Technology's Jet Propulsion Laboratory.
The Greenland study is the latest of several in recent months that have found evidence that rising temperatures are affecting not only Earth's ice sheets but also such things as plant and animal habitats, coral reefs' health, hurricane severity, droughts, and globe-girdling currents that drive regional climates.
