    Under the Dead Sea, Warnings on Climate and Earthquakes

          An international team of scientists drilling deep under the bed of the Dead Sea has found evidence that the sea may have dried up during a past warm period analogous to scenarios for climate change in coming decades. With nations in the volatile region already running short on water, the finding could be a…

    Farmers, Flames and Climate: Are We Entering an Age of ‘Mega-Fires’?

    For millennia, people have set fires to clear land for cultivation, pastures or hunting; so-called slash-and-burn agriculture is still common across much of tropical Africa, Asia and South America. It has been a useful strategy–but …

    PhD. Ode to a Tree

    “I was deeply saddened by the loss of one of our most beautiful trees on campus during the last storm. It had perfect symmetry and such a beautiful color display late in the fall,” wrote geochemist Martin Stute, after a highly unusual heavy October snow felled a 22-year-old Bradford pear at Lamont-Doherty Earth Observatory, where he…

    Winter Extremes: So Last Year?

    What are the odds that this winter will be as snowy as the last two? Climate scientist Jason Smerdon and tree-ring scientist Rosanne D’Arrigo are working on an answer, looking at the long-term history of two important weather patterns—the North Atlantic Oscillation and La Niña state in the tropical Pacific—that similar to last year could…

    Asia’s Motown Meets Waterworld–The Global Water Supply Chain Crisis

    Since July, an almost unceasing torrent of rain has soaked Thailand, flooding farms, roads, factories, and finally Bangkok itself, a city of some 12 million people; so far at least 500 people have died. To date the government has ordered evacuations of 12 of the city’s 50 districts, even as water continues to creep through…

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
