    Rapid-Fire Cyclones over the North Indian Ocean

    With Chapala’s destructive landfall in Yemen just a couple of days in the past, a second tropical cyclone, Megh, has just formed in the Arabian Sea. This one is not forecast to become anywhere near as intense as Chapala did—though we know intensity forecasts can be wrong, as they were at early stages for both…

    Historic Hurricane Nears Landfall on Southwest Coast of Mexico

    Hurricane Patricia, the strongest hurricane ever observed in either the Atlantic or eastern Pacific, is expected to make landfall on the Southwest coast of Mexico this afternoon and evening as an extremely dangerous Category 5 hurricane.

  • Pani, Pani Everywhere

    Pani, Pani Everywhere

    Heading out to our field area, we discovered that the abandoned river valley we planned to study was completely flooded. There was pani—the Bangla word for water—everywhere.

    Bangladesh and India, Too

    Returning to Bangladesh for additional fieldwork, I stopped off in India for several meetings, but we found time for some sightseeing, too. We were able to see the Qutub Minar complex in Delhi as well as the Taj Mahal and Agra Fort in Agra. Plus all the meetings in Delhi, Kolkata and Dhaka were very…

    How Superstorm Sandy Inspired an Award-Winning Book

    “A lot of the challenge is understanding what we as a species should do, because the disasters are getting more prevalent. In the last hundred years, both in human and financial costs, damages are skyrocketing. Most of that is just more people living in dangerous places, but climate change will be more of a factor…

    A Simple Question, Unexpected Applications – and an Award

    Even the simplest research questions can lead to far-reaching public benefits. Consider Chris Small and Joel Cohen’s study of global population by altitude, being honored this week at the Library of Congress.

    From the Field: Mapping Lava Flows in Iceland

    Lamont’s Einat Lev and Elise Rumpf write about their expedition to the lava fields of Iceland, where the two volcanologists and a drone named Buzz studied how lava flows and what happens to rivers, rocks and old lava in its path.

    Bringing Together Storm Tracks and Clouds

    The storm tracks define the weather and climate in mid-latitudes. A recent workshop in Switzerland highlighted the important role that clouds play for the response of the storm tracks to climate change.

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
