Big Antarctic ice sheet appears doomed
Warming climate is expected to trigger the sudden retreat of a partially floating glacier on the continent’s western side by 2100.

Sediments show bipolar melting cycle
Both the North and South Poles have experienced regular and simultaneous periods of significant melting during the past 3 million years, according to sediments from the ocean floor at high latitudes.

Antarctic glacier thins and speeds up
One of the largest glaciers in Antarctica is growing thinner and retreating inland, spurring concerns that changes occurring along the coastline may be causing the ice stream to drain more material from the interior of the continent and send it out to sea, thus aggravating rising sea levels.

Living it up below the ice sheet?
A recent earthquake in Antarctica points toward geologic activity that could provide the energy necessary to incubate life in a liquid lake deep beneath the ice.

Lasers show atmosphere differs from models
New observations of the middle and upper atmosphere over Earth's polar regions may require scientists to revamp their mathematical models of temperature and other environmental conditions at high altitudes.
