Melting Antarctic ice sheet

Frank Ford sent me a very alarming article from The Independent called "Scientists sound alarm over melting Antarctic ice sheets". Here's part of what it says:

The long-term stability of the massive ice sheets of Antarctica, which have the potential to raise sea levels by hundreds of metres, has been called into question with the discovery of fast-moving rivers of water sliding beneath their base.

Scientists analysing satellite data were astonished to discover the size of the vast lakes and river systems flowing beneath the Antarctic ice sheets, which may lubricate the movement of these glaciers as they flow into the surrounding sea.

The discovery raises fresh questions about the speed at which sea levels might rise in a warmer world due to the rate at which parts of the ice sheets slide from the land into the ocean, scientists said at the American Association for the Advancement of Science in San Francisco. ...
The West Antarctic ice sheet is the second biggest on the continent, and the rate at which ice flows from it to the Ross ice shelf, and then ultimately into the sea, is critical in assessing the likely impact of climate change on global sea levels.

Very worrying. Now is Bush going to be made aware of this study? Will he even care?
