    Student ‘Aquanauts’ to Tackle Water Issues

    “We would like to take on international problems, problems of development, problems in the United States, but have them done with academic content and interest. Instead of people being sent to random places, we would take engineering companies that have an interest in a particular region in solving a problem, and they would bring the…

    Slicing Silicon Thinner to Cut the Price of Solar Cells, NY Times, Mar 13: The cost of silicon has been an important barrier to expanding the penetration of solar photovoltaic power. New manufacturing techniques using less silicon could help dramatically reduce the price of producing solar cells, potentially helping expand the industry and bringing down…

    The Sundarbans

    After finally reaching the Mongla and our boat, we settled into our new home. It is a similar design, but much larger than the one we used in September. As we ate dinner and explored the ship, it started the overnight journey to the southeastern part of the Sundarbans where the wildlife is most plentiful.…

    Rivers and the Road

    We spent a day on the islands (chars) in the Brahmaputra River seeing the geology and talking to the residents. Then after an evening of feasting and dancing in our new Saris and lungis, we hit the road for the trip to the Sundarbans.

    At the Bottom of the Bottom of the World

    As we in North America emerge from a remarkably mild winter, the brief and sunny summer in the world’s deep south is drawing to a rapid close. Antarctica’s days are becoming shorter, and come the vernal equinox the South Pole will enter into its yearly hibernation—six months of dusk and night. Researchers from Columbia University…

    Class Trip – to Bangladesh

    To help my students in a class on hazards of Bangladesh better understand the country, I am taking them there to experience Bangladesh for themselves.

    Climate Change May Kill OFF 900 Bird Species, Treehugger, Mar 7 Scientists say climate change is likely to drive up to 900 bird species into extinction by the end of the century unless additional conservation measures are taken. Tropical bird species are particularly vulnerable because they are adapted to living in a stable climate, where…

    Climate Services: Bring In Many Perspectives, Early On

    What’s a “climate service”? Depends on whom you ask, which is why it is crucial to bring as many different perspectives to the table, says Guy Brassuer, head of Germany’s Climate Service Center.

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
