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.

Shifting Monsoon Altered Early Cultures in China, Study Says
The annual summer monsoon that drops rain onto East Asia has shifted dramatically, at times moving northward by as much as 400 km and doubling rainfall in that northern reach. The monsoon’s changes over the past 10,000 years likely altered the course of early human cultures in China, say the authors of a new study.

James Hansen Honored for Pioneering Work in Climate Change Modeling
James Hansen, director of the Program on Climate Science, Awareness and Solutions at the Earth Institute and former director of the NASA Goddard Institute for Space Studies, is being honored with the BBVA Foundation Frontiers of Knowledge Award in Climate Change.
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
