The Columbia Glacier: Climate Change and Glacial Dynamics

One of the most rapidly changing glaciers in the world shows us that once climate change triggers retreat, glacial mechanics can make melting a whole lot worse.

Tiny Losses of Ice at Antarctica’s Fringes May Hasten Declines in Interior

A new study shows that even minor deterioration of ice shelves can instantaneously hasten the decline of ice hundreds of miles landward.

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.

Iron Chemistry Matters for Ocean Carbon Uptake

An interdisciplinary team of scientists has discovered that, contrary to general scientific belief, iron in nondissolved particle form can stimulate phytoplankton growth, and that the chemical form that particulate iron takes is critical to ocean photosynthesis.

Palcacocha Icefalls Demonstrate Hazard Vulnerabilities in Peru

In the last week, calving events at Lake Palcacocha in the Peruvian Andes released masses of ice from a glacier on Mount Pucaranra, showing the weakness of the existing infrastructure designed to protect the region from floods.

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.
