As climate warms, the surface of the Greenland ice sheet is melting, and all that meltwater ends up in seasonal rivers that flow to the sea. At least that is what scientists have assumed until now. A new study has shown that some of the meltwater is actually being soaked into porous subsurface ice and held there, at least temporarily.

Organic geochemist Pratigya Polissar is developing new tools to look at the history of plants and ecosystems on Earth over the past 20 million years.
A plankton-like species is attacking the base of the food chain in the Arabian sea, disrupting water quality and killing fish. Researchers at the Lamont-Doherty Earth Observatory are learning how to fight back.

If we ate half as many burgers and steaks each week, a new study calculates that it could have a profound effect on carbon emissions and the environment.
In a remote desert region around Kenya’s Lake Turkana, paleoecologist and geochemist Kevin Uno collects fossils and sediments, searching for evidence about past climate, vegetation, animals, and water. His goal: to understand how climate affected our ancestors millions of years ago.
The Rosetta team made two big accomplishments this week: Our lidar returned some beautiful 3D images of the sea ice topography, which can be used to study small details of the ice. And our own Chloe Gustafson won first place in the Antarctic Turkey Trot. She now holds the honor of being the first woman to win the race!
Students from the MPA in Environmental Science and Policy program at SIPA have produced a podcast called “Greener on the Other Side,” on sustainability, climate change, and the environment.
Seismologist Lynn Sykes has been working for more than 50 years to halt the testing of nuclear bombs. In his forthcoming book, Silencing the Bomb: One Scientist’s Quest to Halt Nuclear Testing, Sykes provides an insider’s look at the science behind detecting explosions, and international efforts to establish a series of treaties.
