    Scientists Say They Now Know Why Antarctic Meltwater Stays Below Ocean Surface

    Up to now, it has been a mystery why much of the fresh water resulting from the melting of Antarctic ice shelves ends up in the depths instead of floating above saltier, denser ocean waters. Scientists working along one major ice shelf believe they have found the answer.

    ‘Tail Risk’: a Chat with Scientist Radley Horton

    We’re talking to experts around the Earth Institute about what they’re working on, what they would like people to know about it, and what inspired them to go into their field.

    2016 Sets Another Record for Warmth

    The news doesn’t come as a surprise to scientists and others who’ve been watching, but marks a milestone nonetheless: 2016 was the warmest year on record, dating back to the start of modern record keeping in 1880.

    Radar Reveals Meltwater’s Year-Round Life Under Greenland Ice

    An improved technique developed by a graduate student at Lamont-Doherty Earth Observatory and her colleagues is making it possible to use airborne ice-penetrating radar to reveal meltwater’s life under the ice throughout the year.

    Exploring Our Changing Earth, in Real Time

    Lamont-Doherty Earth Observatory scientists are loading drones with high-tech instruments and using satellites and undersea cables that are interacting with sensors in some of the most remote locations on Earth to gather data in real time and uncover the secrets of our planet.

  • Environmental Science and Speaking Truth to Power

    Environmental Science and Speaking Truth to Power

    Denying the science of global warming is absurd, but accepting the science of climate change does not require decision-makers to accept the policy prescriptions of climate scientists.

  • Spring 2017 Undergraduate Research Assistant Opportunities

    Undergraduates from Columbia and Barnard will be able to serve as research assistants on research projects related to sustainable development and the environment with distinguished faculty and researchers at the cutting edge of this burgeoning field.
