For Rio+20, a Call to Preserve Biodiversity
An estimated 9 million species of living things inhabit the Earth. But those species are disappearing at an alarming rate, and this loss of biodiversity appears to be a major driver of environmental changes that can affect the biological and chemical processes that humans rely on.

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
