    Photo Essay: High in the Hills, Climate May Challenge Forests

    Forests in the south-central United States are some of the country’s most productive and diverse. They also sit in a warming “hole”—an area where the progressive rise in temperature affecting most of the continent hasn’t yet taken hold. A team from Columbia University’s Lamont-Doherty Earth Observatory is studying how these forests might shift—or even disappear—when…

    How Will Shifting Climate Change U.S. Forests?

    One foggy spring morning just after a hard rain, Park Williams was tromping through the woods deep in Arkansas’ Ozark Mountains. Toiling down a steep slope, he supposedly was keeping a simultaneous eye out for rattlesnakes, copperheads, poison ivy and big old trees. Williams seemed mostly focused on the trees, though; attention to the other…

  • The Technological World and the Risk of Nuclear Power

    The modern economy and our way of life depend on new and advancing technology. It especially depends on energy technology.

    Questioning Carbon Capture and Storage

    With billions of dollars around the world being invested into carbon capture and storage, often in the energy sector, there are compelling questions to ask about when, where and for what purpose we use this technology.

    Mozambique Core Brings Up 7 Million Years of Climate History

    With calm seas, the JOIDES Resolution’s latest sediment core comes up with what appears to be a fantastic, cyclic climate signal that is continuous back 7 million years, writes Sidney Hemming.

    Attributing Extreme Weather to Causes—Including Climate Change

    New research and more powerful computer models are advancing scientists’ ability to tease apart the forces that can worsen extreme weather. In a new report, a committee of the National Academy of Sciences that includes Columbia’s Adam Sobel assesses the young field of attribution studies.

    Pump Meltwater Back on Antarctica? Do You Have 850,000 Wind Turbines?

    A new study that looked at the feasibility of lowering sea levels by pumping water onto icy Antarctica offers a warning about the costs today’s greenhouse gas emissions may be creating for future generations.

    Scientists Prepare ‘Climate City’ for Take-Off

    Sometime soon, a flock of “Climate Birds” could be ascending from a former NATO base in northeast France to take the measure of climate change around the world.

    We’re Headed for Mozambique!

    After weeks of anticipation, permission arrived just in time to core off Mozambique. Sidney Hemming and her team of scientists aboard the JOIDES Resolution are excited about what they might learn from the ocean sediment.

COP31, the 2026 United Nations Climate Change Conference, aims to advance dialogue, strengthen consensus, and accelerate climate action on a global scale. From November 9–20, 2026 in Antalya, Türkiye, heads of state, ministers, scientists, business leaders, and civil society will gather to advance efforts in emission targets, climate finance, and adaptation and resilience. Once again, our experts, students, and global thought leaders from Columbia Climate School and across Columbia University are contributing to key events, sharing insights, and helping shape the dialogue toward ambitious, science-based solutions.
