Apparently theres been a dramatic increase in the glacier melting speed in the past 10 years. Ice detorration has increased 25% more in the past 10 years compared to data ranging back 30 years.

Many glaciers in West Antarctica have substantially increased their rate of shrinkage compared with the 1990s.

US-Chilean teams report to the journal Science that the glaciers are losing 60% more ice into the Amundsen Sea than they accumulate from inland snowfall.

They say the ice loss corresponds to an annual sea-level rise of 0.2mm, or more than 10% of the total global increase of about 1.8mm per year.

Bob Thomas, who is attached to the US space agency's (Nasa) Wallops Flight Facility and one of the authors on the Science report, cautions that the observed changes apply to only a short time period.

It is too early, he says, to tell if the accelerated thinning is part of a natural cycle or is a sign of a longer-term change. "Continued observation is important," he added.

And Eric Rignot, a study participant from Nasa's Jet Propulsion Laboratory, said: "The rates of glacier change remain relatively small at present... But the potential exists for these glaciers to increase global sea level by more than one metre.

Didn't see anywhere in the article where it was attributed to global warming. Was there other information about this?


If they sped up alittle more, we could have a new sport.....Ice Surfing!!!!

Correct, I took out the part about global warming causing it.. lil premature ;-)

Well regardless of wether its Global Warming or the Earth naturally setting up for a pre-Ice Age it concerns me.
