News from the Columbia Climate School

Author: Kevin Krajick21

Kevin Krajick was from 2007-2025 the senior editor for science news at the Earth Institute and the Columbia Climate School. He grew up in the Catskill Mountains and Hudson Valley of upstate New York, where he worked at his high-school newspaper. He has since reported from all 50 U.S. states and 30-some countries, writing about science, medicine, crime, immigration and other issues. His work has appeared in National Geographic, Newsweek, The New Yorker, Science, Smithsonian and many other publications. He was a finalist for the National Magazine Award for Public Service for his reporting on organized crime’s links to the toxic waste-disposal industry. He is two-time winner of the American Geophysical Union’s Walter Sullivan Award for Excellence in Science Journalism, and his work has been featured repeatedly in the yearly book “Best American Science and Nature Writing.” His 2001 book “Barren Lands” is the true account of how two prospectors discovered vast deposits of diamonds in Canada’s remote far north. Krajick holds degrees in comparative literature and journalism from Columbia University. He lives on the Upper West Side of Manhattan with his family.

The Greenland Ice Sheet Is Sponging Up Meltwater

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…
American Geophysical Union 2017: Key Events From the Earth Institute

A chronological guide to key talks and other events presented by Columbia University’s Earth Institute at the American Geophysical Union 2017 meeting.
Ear to the Ground, Listening for Nuclear Blasts

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.
Ocean Sediments Off Pacific Coast May Feed Tsunami Danger

Tightly packed sediments help the Cascadia Subduction Zone generate large earthquakes, and could boost its ability to trigger a large tsunami.
Where Is All That Carbon Dioxide Going?

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.
National Climate Report: Q&A With Authors

Every four years Congress is provided with a state-of-the-art report on the impacts of climate change on the United States. The next National Climate Assessment is scheduled for 2018, but its scientific findings are scheduled to be published today. Here, two of its authors explain what to expect.
In Biblical Land, Searching for Droughts Past and Future

Human-influenced climate warming has already reduced rainfall and increased evaporation in the Mideast, worsening water shortages. Up to now, climate scientists had projected that rainfall could decline another 20 percent by 2100. But the Dead Sea cores suggest that things could become much worse, much faster.
Photo Essay: The Dead Sea, Living Waters and Megadrought

Thousands of years before Biblical times, during a period when temperatures were unusually high, the lands around the Dead Sea now occupied by Israel, Jordan and surrounding nations suffered megadroughts far worse than any recorded by humans. Warming climate now threatens to return such conditions to this already hard-pressed region.
Under the Sea Ice, Behold the Ancient Arctic Jellyfish

A video reveals mature jellyfish under the Arctic sea ice, where they aren’t supposed to be.
