8 Ways We Can Strengthen Development and Increase Climate Resilience
President Obama this week announced a set of actions designed to help populations here and abroad develop better resilience against drought, sea level rise and other consequences of a changing climate. At The Earth Institute, the International Research Institute for Climate and Society has been working on these issues for years — making regular climate…

What Everyone Should Know About Climate Change
Climate scientist William D’Andrea of the Lamont-Doherty Earth Observatory asked young scientists attending a symposium last October, “What do you wish everyone knew about climate change?” He turned the responses into this video, which covers the topic pretty well.

Ocean Sediments Tell a Surprising Climate Story
Geochemists Alexander van Geen and Jacob Mey helped coauthor a recent paper in the leading journal Science showing that warming climate in the future may not degrade oxygen supplies in some parts of the oceans as previously thought.

What Geology Has to Say About Global Warming
The most important lessons drawn from geology are that the earth’s climate can change radically, and rapidly. We can’t say precisely at what CO2 level we’re in danger of melting Antarctica, but that threshold could be reached in 150-300 years, if CO2 levels keep rising at the current rate.

Gavin Schmidt Named Director of Goddard Institute for Space Studies
NASA has named Gavin A. Schmidt to head its Goddard Institute for Space Studies (GISS), an affiliate of Columbia University’s Earth Institute. Currently serving as deputy director, Schmidt takes over from long-time director James E. Hansen, who retired last year to open a separate climate science and advocacy center at the Earth Institute.

How High Will Sea Levels Rise?
Scientists from Lamont-Doherty Earth Observatory are trying to determine how high sea levels may rise in the future by studying the shorelines of the past. Led by a team of researchers including Lamont climate scientist and marine geologist Maureen Raymo, the goal of Pliomax is to increase the accuracy of global sea level estimates for…

Clock Is Ticking in West Antarctic
“The high-resolution records that we’re getting and the high-resolution models we’re able to make now are sort of moving the questions a little bit closer into human, understandable time frames.”

Climate Report Author to Take Questions on Friday
Climate scientist Radley Horton, one of the lead authors of the National Climate Assessment report released this week, will answer your questions in an “ask me anything” session on Redditt on Friday starting at 11 a.m.
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
