Glaciers in Antarctica are thinning faster than they did in the 1990s and researchers have discovered an unexpected folded section deep beneath the ice cap, findings that may indicate the ice is less stable than had been thought.    Glaciers in West Antarctica are discharging 60 percent more ice into the sea than they are accumulating from snowfall, a research team led by Robert Thomas at NASA Goddard Space Flight Center in Wallops Island, Va., reports in Thursday's issue of the journal Science...

Icebergs that break off Antarctica and drift away turn out to be hotspots of life in the cold southern ocean, researchers report. Climate warming has led to an increase in the number of icebergs breaking away from the Antarctic in recent years, and a team of researchers set out to study the impact the giant ice chunks were having on the environment.
