Kaplan studies the ways ice sheets, mountain glaciers, climates and landscapes changed in the past.

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.

A new study finds that land subsidence is outpacing ocean-driven sea-level rise along the northern coastline of Java Island, Indonesia.

This research identifies a diverse set of molecules released by marine phytoplankton that fuel microbial life and help drive Earth’s carbon cycle.

Once again, we honor Earth Day by sharing some amazing photos celebrating the beauty and magic of our planet, as captured by the Columbia community.

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

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.

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

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.

Raymo received the award for her pioneering development of hypotheses that explain climate change across Earth’s history, and her educational leadership in the Earth system sciences.

Antarctica’s Ross Ice Shelf and the West Antarctic Ice Sheet may have been far smaller during one of Earth’s most recent warm periods, according to a new study.

Researchers have found that Earth’s underlying crust in the Turkana Rift region has been significantly thinned, presaging Africa’s eventual breakup—and with that finding, the researchers offer a new perspective on Turkana’s fossil record of human evolution.
