  • Earth, Water and Sky –A Conversation with Pierre Gentine, a new Columbia Water Center Scientist

    Earth, Water and Sky –A Conversation with Pierre Gentine, a new Columbia Water Center Scientist

    Columbia Water Center welcomes Pierre Gentine, Assistant Professor of Applied Mathematics at Columbia University’s School of Engineering and Applied Science, as an affiliate researcher. Pierre’s groundbreaking research on the way soil moisture interacts with the atmosphere has implications for many of CWCs initiatives—from developing more efficient irrigation systems, to water resource management, to understanding floods.…

  • Switchyard Project: New Sampling Record

    Switchyard Project: New Sampling Record

    On May 10, we celebrated the sampling of our 10th station yesterday. These are more stations than we were ever able to get water samples from. Because of the ongoing good weather, we will certainly get one more station today, and hopefully many more during the next couple of days. So watch the posted video and celebrate with…

  • Switchyard Project: Sampling Success

    Switchyard Project: Sampling Success

    The past 1½ weeks have been very successful. Our team from Lamont-Doherty Earth Observatory was able to obtain water samples from eight stations, while the team from the University of Washington has already broken their all-time record of the past years of 18 stations. Today (May 7) is actually the first day we can’t fly…

  • Transporting Ice From Greenland’s Deep Interior

    Transporting Ice From Greenland’s Deep Interior

    The North East Ice Stream is a fast-flowing glacier transporting ice from deep in the interior of the Greenland Ice Sheet out to the coast (see image showing a deep penetration into central Greenland). When it reaches the coastline it feeds 79 N Glacier. This area is heavily crevassed, evidence of the rapid ice flow.…

    Climate News Roundup: Week of 5/01

    California Gambles on Carbon Trade, New York Times, May 1 California state regulators are working to prepare for the January 1rst start of the multibillion-dollar carbon market, which will be the first in the U.S., after a lawsuit delayed the process. The courts are still a challenge with opponents striking from both the left and…

    Climate Clock is Ticking for Pinot Noir

    New studies of temperature records, grape harvests, and climate fluctuations over the Atlantic Ocean are yielding insights into how climate change might impact the production on Pinot Noir.

  • Switchyard Project: Rescue Operation

    Switchyard Project: Rescue Operation

    Four people who tried to ski from the North Pole to Greenland got stuck on the ice and ran out of food. Since our team was out on the ice for sampling close to their location, we stopped sampling and picked them up.

  • Switchyard Project: It’s all about the weather

    Switchyard Project: It’s all about the weather

    One can only imagine what kind of a pilot one has to be to fly in the arctic regions and land on sea-ice under weather conditions as we have experienced already – fog above the ice and clouds covering the area with very low visibility.

  • How to reduce weather risk (and make a little green)

    How to reduce weather risk (and make a little green)

    People understand that weather can affect certain markets — especially energy prices and other commodities — but its impact on portfolios more broadly might surprise. Just last week, a new study was released that estimated $485 billion of annual weather-related economic impact in the United States alone. Another calculated the effect at nearly 10 times that amount…

AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
