    Photo Essay: Land, Lava, People

    On Hawaii, lava is a way of life. The whole island is made of the stuff. Eruptions from Kilauea volcano have been adding new land and wiping out old for all of human time, and far before. In recent decades, lava flows have wiped out communities and major roads. The latest eruption, which began in June 2014, now…

    In Hawaii, Living With Lava

    When the most recent eruption of Hawaii’s Kilauea volcano started last June, Melvin Sugimoto at first did not think much of it. Hawaii, where he has lived all his life, is made entirely of hardened lava, and Kilauea, perhaps the world’s most active volcano, has been adding more off and on for the last 300,000 years. “Lava is…

    Exploring Beneath Earth’s Changing Ice Sheets

    If just the West Antarctic Ice Sheet were to melt, it would raise global sea level by 6 meters. That’s more than a theoretical problem. West Antarctica is losing ice mass, and scientists are worried.

  • Earth’s Magnetic Field: Just Returning to Normal?

    Earth’s Magnetic Field: Just Returning to Normal?

    Earth’s magnetic field is getting weaker, but it may simply be coming down from an abnormally high intensity rather than being a sign of an impending geomagnetic reversal.

  • Climate Is Changing Fast in West Antarctica

    Climate Is Changing Fast in West Antarctica

    Fast-rising temperatures on the Antarctic Peninsula are having an impact on the ice and marine life, and providing clues about future ecosystem changes elsewhere.

    In One Simple Line of Data You Can Read a Full Story

    The lines of data are slowly creeping across our Ross Ice Shelf GIS map and with each new line comes an improved understanding of Ross Ice Shelf. What can you learn from a ‘snapshot’ of data? A radar contains a nice story.

    Peat Fires Choking Southeast Asia Pose a New Threat to Global Climate

    The Indonesian peat fires that have been choking cities across Southeast Asia with a yellow haze are creating more than a local menace—burning peat releases immense stores of CO2, contributing to global warming.

    Ancient Faults & Water Are Sparking Earthquakes Off Alaska

    Ancient faults that formed in the ocean floor millions of years ago are feeding earthquakes today along stretches of the Alaska Peninsula, and likely elsewhere, a new study suggests.

    Unlocking the Secrets of the Ross Ice Shelf

    The Ross Ice Shelf is much like the Rosetta Stone. The historic stone inscribed in three scripts told the same story but in different tongues, so when matched together scholars could decode an ancient language. The Antarctic Rosetta Project also brings together three different “scripts,” each written by an Earth system; the ice, the ocean…

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
