The Big City, Subdivided for Sustainability
Two-thirds of people on the planet will live in cities by 2050. But few cities are prepared for this population boom. An upcoming research project will explore new, localized models for urban infrastructure to make cities cleaner, healthier and more enjoyable places to live.
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
