    Making Fish Farming More Sustainable

    Global per capita fish consumption has almost doubled in the last 50 years. And today, about half of all the seafood we eat is produced through fish farming, aquaculture. Can it be done sustainably?

  • Coastal Erosion and Adaptation to Climate Change

    Coastal Erosion and Adaptation to Climate Change

    Increasing understanding of the extent of coastal erosion and its interaction with other naturally existing geographical features such as mangrove vegetation is one of the areas of research that may help reduce vulnerability of small-island developing states to climate hazards.

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
