The Sustainable City
By concentrating human population in cities, we will make it possible to preserve land for wilderness, ecosystem maintenance and agriculture. People will travel to these places and will experience nature, but only a fortunate few will live close to nature.

In the Southern Ocean, a Carbon-Dioxide Mystery Comes Clear
Twenty thousand years ago, low concentrations of carbon dioxide in the atmosphere allowed the earth to fall into the grip of an ice age. But despite decades of research, the reasons why levels of the greenhouse gas were so low then have been difficult to piece together. New research, published today in the leading journal…
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
