  • Climate News Roundup – Week of 5/31

    United States Climate Report to UN Projects 4% Emissions Rise by 2012, Associated Press (via Metronews Halifax) On Tuesday, the U.S. delivered its first emissions report to the United Nations since 2006.  The projections indicate about a 4% increase in emissions between now and 2020, which includes a 1.5% rise in CO2 emissions.  The emphasis…

  • Losing your glaciers? Build your own.

    Scientific American has an interesting photo piece by Gaia Vince about a place in the Himalayas that is adapting to climate change by creating its own glaciers.

  • An Active Hurricane Season Predicted

    The IRI’s latest forecast for the Atlantic hurricane season, which started June 1, points to significantly increased hurricane activity this year. In fact, the likelihood of having an above-normal year is more than three times that of having a below-normal year. This could spell trouble for highly vulnerable Caribbean nations such as Haiti – still…

  • High Elevation Lakes

    We are currently taking samples of water and sediments from high-elevation lakes near the glaciers. Like ice cores from the glaciers themselves, these should contain substances that will help us understand the climate history of this region. The sampling is being done in conjunction with the Indonesian Institute of Sciences and the Indonesian Meteorological, Climatological…

  • Needed: Ice Drills

    We are staying at the high-elevation Grasberg gold and copper mine—not on top of Puncak Jaya—because some of our equipment has not arrived. We have 99 pieces out of the 106 we shipped, but unfortunately our ice drills are in the missing pieces, and we cannot do anything without those. We are working hard to…

  • Scouting the Glacier

    Team members are now actively scouting by foot on Puncak Jaya, looking for the best drill spots, travel routes  and campsites. The man in red is Broxton Bird of Ohio State University. In brown, the appropriately named alpine veteran Keith Mountain of  the University of Louisville. At bottom: team leaders Dwi Susanto and Lonnie Thompson give a…

  • Climate and Public-Health Communities Train Together

    For the third year in a row, public-health professionals and climate scientists from around the world are visiting Columbia University’s Lamont campus, where the International Research Institute for Climate and Society is based, to learn how to use climate information to make better decisions for health-care planning and disease prevention. They’re taking part in the…

  • Predicting Rainfall in Senegal and the Sahel

    Last week Ousmane Ndiaye, a graduate student at DEES and a graduate research assistant at the IRI, gave his thesis defense to a packed house in Monell. The presentation, entitled “Predictability of the Sahel Climate: Seasonal Sahel Rainfall and Onset over Senegal,” considered issues of rainy-season predictability in Ndiaye’s home country. It also earned him…

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
