East Antarctic Ice Sheet Should Remain Stable Even if the West Melts

A new look inside the ice sheet validates predictions that it probably won’t melt as quickly as its neighbor—good news, since East Antarctica contains enough water to raise sea levels by 200 feet.

Christine McCarthy: A Cheerleader for the Physics of Ice

Christine McCarthy, a geophysicist at the Lamont-Doherty Earth Observatory, scrunches blocks of ice between hunks of rock to study how ice behaves under pressure. Her work provides an important piece of the puzzle of how glaciers move, what makes them speed up, and how they are contributing to sea level rise as the climate warms.

Meltwater Lakes Existed Under Antarctic Ice in Ancient Times

In recent years, scientists have discovered hundreds of lakes lying hidden deep beneath the Antarctic ice sheet. Now a team of researchers has found the remains of at least one sub-ice lake that existed when the ice was far more extensive, in sediments on the Antarctic continental shelf.
