Glacial Geoengineering: The Key to Slowing Sea Level Rise?
A new proposal suggests building underwater walls to protect glaciers from warm water. Here’s how it might work.

Reflections from Antarctica: A Landscape in Flux
Working as an Antarctic field scientist, I witnessed the destruction provoked by a rapidly warming planet. But I also found inspiration.

German Court Will Hear Case Against Greenhouse Gas Emitter
A Peruvian farmer is suing energy producer RWE for increasing the threat of glacier lake outburst floods that endanger his home.

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.
