Corals and Climate Change
Corals are already facing a host of stressors—from pollution and overfishing to tourism and coastal development—but climate change puts corals at risk from rising temperatures and ocean acidification. The decline of coral reefs will have devastating consequences for the ocean, and for us.

The Extreme Pacific Climate Now
The climate over the tropical Pacific is in an extreme state at the moment. That explains some of the extreme anomalies affecting the United States right now. It also gives us a window through which we can glimpse how even more dramatic and long-term climates of the distant past might have worked.

As we flew from Guiyang to Beijing for the return flight home, I looked down and saw a countryside dotted with scores of windmills. The transition from a coal-based economy to…
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
