Yes, We Can Afford to Remove Carbon from Air
Recently, the American Physical Society (APS) released a report on the direct capture of carbon dioxide from air. The report concludes that air capture could be a powerful tool for mopping up carbon dioxide emissions that otherwise would escape to the air, for providing carbon dioxide for synthetic liquid fuels in the transportation sector, and…

Understanding the Mind as the Temperature Climbs
Warnings of potentially cataclysmic climate change have reached nearly every newspaper front page and legislative chamber around the globe since the 1990s. So why has the human response been so limited?
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
