    America’s strong water infrastructure has been key to its success as a nation. Yet the nation’s continual waste of water and lack of commitment to long-term water investments has halted its progress.

  • Students Share Findings from Global Research

    This April over fifty students shared the results of their respective research projects with the rest of the Columbia community as part of the 2013 Student Research Showcase. While all within the field of sustainable development, research topics ranged from climate change to community development and included work from across the world.

    Singing the Blues About Water Scarcity

    Otis Redding sang “you don’t miss your water ’til your well runs dry” in 1965 about pining for a lost love. Last week, Climate and Society founder and Lamont-Doherty Earth Observatory scientist Mark Cane reprised it with a much different, more literal focus: water scarcity in the 21st century.

    Jamuna River

    The last part of our river work was on the Jamuna River, as the Brahmaputra is called south of where if diverges from its former course. It shifted up to 100 km to this course about 200 years ago. We visited Sirajganj where an embankment protects the city from the migrating river and Aricha near…

    Brahmaputra chars

    We traveled to the Brahmaputra River, one of the most active on the planet, to continue our fieldwork. We visited two places while working our way downstream and saw the rapid changes in the river bank and chars (islands). At one ghat (dock) the river had eroded a mile of the coast while in the…

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
