Greenland’s ice sheet is slip-sliding away

Front-page Sunday L.A. Times yesterday.

The massive glaciers are deteriorating twice as fast as they were five years ago. If the ice thaws entirely, sea level would rise 21 feet.

Climate experts have started to worry that the ice cap is disappearing in ways that computer models had not predicted.

In a way no one had detected, the warm water made its way through thousands of feet of ice to the bedrock — in weeks, not decades or centuries.

“This meltwater acceleration is new,” Zwally said. “The significance of this is that it is a mechanism for climate change to get into the ice.”

This is observable fact. Not speculation. Clearly, something major is happening with the climate. Enormous ice sheets don’t just up and start melting for no apparent reason.
