Antarctic Glaciers Moving To Sea Faster

The British Antarctic Survey team studying 300
glaciers found that they are flowing into the sea
at a faster pace than scientists have ever seen.
As the glaciers melting is accelerated, the melt
water contributes to the faster movement.
"We're only just now getting to grips with just how big these dynamic processes may be. There are still a lot of surprises out there," said David Vaughan, a glaciologist at the British Antarctic Survey and a co-author of the study.(1)
The sea level rise predicted by scientists must be re-calculated but they don't know by how much yet.
South America
Scientists studying the Andeas Mountains predict the glaciers there will be gone in 30 years, and one will be melted away within the next two years. Areas of the region are expectd to double in population by 2050 and there is great concern about the water shortage that is inevitable.
Glaciologist Edson Ramirez stated "This is a process that unfortunately is now irreversible".(2)
US Gov't. Action
These discoveries are coming at a time that the Bush administration has drastically reduced the budget of NASA which will greatly hamper US scientists from learning the extent of the glaciers and ice sheets melting. ".....they will face major gaps in data that can be collected only from satellites about ice caps and sheets, surface levels of seas and lakes, sizes of glaciers, surface radiation, water vapor, snow cover and atmospheric carbon dioxide."(3)
Were going to start being blinded in our ability to observe the planet, said Rick Piltz, whose group provided the AP with a previously undisclosed report. Its criminal negligence, and the leaders in the climate science community are ringing the alarm bells on this crisis.
