Glacier melt warning from the Antarctic

A leading member of the U.N. Climate Panel David Vaughan is recording what he says are worrying signs of glacier melt adding to world sea levels.

Vaughan, a glaciologist with the British Antarctic Survey, made his remarks to Reuters in an open speedboat crossing a bay on the Antarctic Peninsula which had been blanketed by ice for thousands of years but is now open water.

The bay is fed by the small Sheldon Glacier which Vaughan used to illustrate his concerns to Reuters correspondent on the scene Stuart McDill.
