    Forecasting Climate’s Effects on Global Food Production

    The worst drought to hit the U.S. in decades has already brought corn yields to a 17-year low and will almost certainly raise food prices. Wealth will soften the blow in the U.S., but in sub-Saharan Africa and South Asia, prolonged drought has often had deadly consequences. Is there a better way to anticipate climate’s…

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
