In a new study, researchers have mapped out a large variety of discarded pharmaceuticals dissolved throughout the Hudson River. They say that in some places, levels may be high enough to potentially affect aquatic life.

On every continent and every ocean, Earth Institute researchers are studying climate, geology, natural hazards, ecology and more. Here is a list of projects in rough chronological order.
Many countries are making progress on improving water sanitation and protecting marine ecosystems. But air pollution continues as a leading health problem in many nations, and fisheries are deteriorating almost everywhere.
A new study projects that in coming decades the effects of high humidity in many areas may surpass humans’ ability to work or, in some cases, even survive.
A new study shows that even minor deterioration of ice shelves can instantaneously hasten the decline of ice hundreds of miles landward.
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.
A chronological guide to key talks and other events presented by Columbia University’s Earth Institute at the American Geophysical Union 2017 meeting.
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.
Tightly packed sediments help the Cascadia Subduction Zone generate large earthquakes, and could boost its ability to trigger a large tsunami.
Concurrent with the announcement that human carbon emissions reached a new peak this year, Galen McKinley, a researcher at Columbia University’s Lamont-Doherty Earth Observatory, discusses the difficulties of tracking the sources and destinations of carbon dioxide.
