    The Science of Carbon Dioxide and Climate

    The vast majority of scientists around the world agree that our climate is changing at a faster rate than ever recorded in human history because of our use of fuels such as coal and oil, so-called fossil fuels. The conclusion rests on basic physics known since the early 1800s, when physical scientists first recognized that…

    In High Sierras, Remnants of Ice Age Tell a Tale of Future Climate

    Aaron Putnam’s research in the California Sierras is part of an effort to study glaciers around the world—in Europe’s Alps, the Himalayas, Mongolia, Patagonia, New Zealand. He’s working on an important piece of the worldwide climate puzzle that can help us understand what’s ahead in a warming world.

    Indonesian Corals Shed Light on Climate System

    A new coral salinity record shows that the location of the most significant hydroclimatic feature in the Southern Hemisphere, the South Pacific Convergence Zone, influences a major Pacific Ocean current.

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
