Slowing ice flows
New satellite study of glacier motion shows stop-and-go ice movement

Greenland’s glaciers — giant, slow-moving rivers of ice — respond dramatically to changes in climate. As temperatures rise, glaciers melt. This adds water to the sea. But in a new study, scientists say that meltwater may not be pouring into the seas as fast as the earlier worst predictions had suggested.
Understanding glacier melt rates is important because the water released can contribute to rising ocean levels. And that sea-level rise may eventually swamp beaches and wipe out oceanfront...
