Making Sense of Climate’s Impact on Food Security
From warmer temperatures to natural disasters such as flooding and drought, changing patterns of climate are having billion-dollar impacts on our food-growing systems. But scientists are struggling to find ways to measure and predict what may happen in the future—and to translate that into policies to help feed a bulging world population.
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
