Rate of discharge at two 
of Greenland’s largest glaciers slows


13 Feb 07 - A U.S. study suggests two of Greenland’s largest glaciers are melting at variable rates and not at an increasing trend.

The glaciers shrank dramatically and dumped twice as much ice into the sea during a period of less than a year between 2004 and 2005.

Then, fewer than two years later, they returned to near their previous rates of discharge.

"Our main point," said Ian Howat, a researcher with the University of Colorado who lead the study, "is that the behavior of these glaciers can change a lot from year to year, so we can’t assume to know the future behavior from short records of recent changes."

Then, even though he has already admitted that "we can’t assume to know the future behavior," Howat goes on to say: "Future warming may lead to rapid pulses of retreat and increased discharge rather than a long, steady drawdown." (Whatever that means.)

(It must be really tough to admit that the rate of discharge has slowed.)
