Folarin Kolawole is one of 15 recipients of this year's National Geographic Society’s Wayfinder Award, which recognizes people whose work is expanding our understanding of the planet and helping to protect its future.

Students and faculty at Columbia’s M.S. in Sustainability Management and Sustainability Science programs turned cutting-edge research on microplastics into Moby Filter, a sustainability startup tackling laundry-induced pollution at its source.

AI is a two-sided coin, with tremendous potential to benefit the environment while also requiring an immense amount of water and energy. How will these two opposing dynamics balance out—or can they?

In honor of this annual U.N. event, we are highlighting our coverage of ocean research and education initiatives at the Columbia Climate School and Lamont-Doherty Earth Observatory.

Laramie Jensen’s interest in inorganic and analytical chemistry led her to the ocean. And then to the North Pole.

Even as trees photosynthesize late into the year, their growth stops by mid-summer, which impacts their carbon uptake.

New findings shed light on a widespread gap in the geologic record, where more than a billion years of Earth’s history appear to have been erased.

From a photography exhibit of a high-mountain community in the Peruvian Andes to leading research by Columbia scientists, a recent panel celebrated the knowledge and work of women in and around glaciers.

Caine’s new book depicts a small community in the glacier-fed Peruvian Highlands as it navigates climate change and social pressures.

A new model shows how levels of the “atmosphere’s detergent” may rise and fall in response to climate change.

Researchers have solved a long-standing atmospheric puzzle: how rising carbon dioxide cools the stratosphere even as it warms Earth’s surface and lower atmosphere.

Scientists estimate that Indonesia will lose its two remaining glaciers by 2030—a warning for glaciers around the world.
