Over the past century, tiny airborne particles have largely cancelled out the effects of greenhouse gases on tropical storm intensity. That's changing, and coastal communities will feel the difference, as Adam Sobel and Suzana Camargo explain.
The U.S. has seen a dramatic increase in the simultaneous occurrence of extremely cold winter days in the East and extremely warm winter days in the West, Deepti Singh found. She says greenhouse gases are likely driving the patterns behind this trend.
How’s the water? It’s a question our scientists often hear along the Hudson River as it flows from the Adirondacks to New York City. This summer, Andy Juhl and a team of scientists working with Riverkeeper conducted an unprecedented health check of the entire river system. Here's what they found.
Large-scale groundwater pumping is opening doors for dangerously high levels of arsenic to enter some of Southeast Asia’s aquifers, with water now seeping in through riverbeds with arsenic at more than 100 times the limits of safety, Ben Bostick and Lex van Geen report. Their findings hold important lessons for groundwater managers.
Michael Steckler and colleagues found new evidence of increasing strain where two tectonic plates underlie the world’s largest river delta. They estimate that at least 140 million people could be affected if the boundary ruptures and that it could change the courses of rivers and the level of land already perilously close to sea level.
Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. In a new study, Ryan Abernathey shows how that seasonal ice migration may be more important for the global ocean circulation than anyone realized.
Join us on October 8 between 10 a.m. and 4 p.m. for the Lamont-Doherty Earth Observatory Open House. Tour a lab, participate in hands-on science demonstrations, or hear world-renowned researchers describe their latest discoveries. We'll be listening to earthquakes and demonstrating the hurling power of volcanoes among our many adventures in science.
Your support can revolutionize Earth science research and education
Lamont-Doherty Earth Observatory seeks fundamental knowledge about the origin, evolution and future of the natural world. Our scientists study the planet from its deepest interior to the outer reaches of its atmosphere, on every continent and in every ocean, providing a rational basis for the difficult choices facing humanity.
