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, adding water to the sea. But in a new study, scientists say that meltwater may not be pouring into the seas as fast as earlier worst-case scenarios had predicted.

Understanding glacier melt rates is important because the water they release can contribute to rising ocean levels — changes that may eventually swamp beaches and wipe out oceanfront building...
