December 08 - The world's fastest glacier, Greenland's Jakobshavn Isbrae, doubled its speed between 1997 and 2003. The rapid movement of ice from land into the sea provides key evidence of newly discovered relationships between ice sheets, sea level rise and climate warming.

The glacier's sudden speed-up also coincides with very rapid thinning, up to 49 feet of ice per year after 1997, according to research published in the Dec. 2 issue of the journal Nature.

Along with increased rates of ice flow and thinning, the thick ice that extends from the mouth of the glacier into the ocean, called the ice tongue, began retreating in 2000, breaking up almost completely by May 2003.

STUDY: OCEAN TIDES ONCE SPREAD MASSIVE ICEBERGS, December 08
Connection between changes in ocean circulation and future climate remains a matter of great interest

Labrador Sea ocean tides dislodged huge Arctic icebergs thousands of years ago, carrying gigantic ice-rafted debris across the ocean and contributing to the ice age's deep freeze, say an international team of university researchers.
The study, published in the November issue of Nature, is the first to suggest that ocean tides contributed to enigmatic Heinrich events, a phenomenon where colossal discharges of icebergs periodically flowed into the North Atlantic from about 60,000 to 10,000 years ago.
