    Fluoridation of Water: Communist Conspiracy, Genuine Threat or Both?

    Who can forget the scene from Kubrick’s classic movie Dr. Strangelove of screws-loose General Jack D. Ripper pontificating to straight-laced British group captain Lionel Mandrake about the dangers of fluoride in water…

    At AGU, Earth Institute’s Columbia Water Center Adds to the Abundance of Scientific Riches

    The annual American Geophysical Union (AGU) meeting is an all-you-can-eat buffet of the most current scientific knowledge available on the planet. Name your pleasure: space, climate change, geomagnetism, nonlinear geophysics, volcanology, biogeosciences, etc. You have to be careful to indulge in moderation over the five-day event, or risk unseemly bloating. The Columbia Water Center contributed…

    A Milestone Worthy of a Party: the Municipal Water Plan in Brazil

    I recently returned from a trip to visit our project site in Ceará, Brazil. While our project has included infrastructure construction, the heart of our work is a municipal water plan (PAM) for Milhã, an area in the central region of the state.

    Is New York City Ready for Drought?

    All day long a flood of thousands scientists and students ebbs and flows across San Francisco’s 4th Street and Howard Avenue, coursing between the cavernous Moscone West and Moscone South convention buildings. The AGU is like a supercomputer of earth science, with human currents of data swapping information, heading from one talk to another, processing…

  • The Columbia Water Center’s New Projects Section

    The Columbia Water Center is pleased to announce the release of a greatly expanded and updated research projects section of its website. The new section includes an interactive map along with updated content on the Water Center’s projects around the world. Find out about our how we’re helping farmers save water with tensiometers in India,…

    India’s Water Is Running Out

    India is running “the largest water-mining project in the world”–and it cannot be sustained much longer, Columbia Water Center researcher Shama Perveen told an audience on Monday. That is mainly because farmers, who depend heavily on irrigation water drawn from underground aquifers, are using far more water than rainfall can replenish. Perveen’s talk, “Quantifying the…

    Parched for Peace: The Fertile Crescent Might Be Barren

    This past October, the Levant Desalination Association and Nosstia, an organization of expat Syrian scientists, arranged a conference in the capital city of Damascus to discuss Syria’s water crisis.

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
