A new study found that when microplastics contact water, their surfaces can become chemically reactive. This could be how they get us sick.

Scientists at Columbia University and Imperial College London have found that the largest canyon system in the solar system is still active and shaping Mars today, billions of years after it first formed.

From October through June, Columbia Climate School researchers and students will host sessions exploring climate and sustainability topics including biodiversity, climate finance, climate action in professional sports and wildfire management.

More than 2,500 visitors explored hands-on activities, lectures and installations at Lamont's campus on Saturday, October 17.

New research shows that 2,000 years ago, remnants of an Arctic ice sheet began growing again, marking the start of a new glacial period—what we commonly call an ice age. But by the 1960s, global warming had raised summer temperatures enough to reverse that growth.

New research could lead to more accurate predictions about how quickly Antarctic glaciers might retreat and raise sea levels.

Robin Bell and Vicki Ferrini reflect on Tharp’s induction into the National Women’s Hall of Fame and how her groundbreaking ocean-floor maps helped establish the theory of plate tectonics.

Panelists discussed how agentic AI is beginning to reshape Earth systems modeling, improve climate predictions and support adaptive decision-making.

In this month's research roundup, we explore how delayed climate action could trigger abrupt changes in the Arctic; what ancient ocean sediments reveal about carbon storage during the last ice age; how fiber-optic cables are improving earthquake monitoring at geothermal sites; and a new timeline of Earth's magnetic reversals.

Climate scientist Marco Tedesco reflects on moderating a recent U.N. panel about early warning in a time of melting ice and sea-level rise, and why this work must extend beyond COP31.

Oobleck, seismology and seafloor sediments bring Earth science alive during the observatory’s annual public celebration.

A Lamont-led study finds that global carbon budgets may underestimate how much carbon dioxide the ocean absorbs by roughly 5% to 15% because they do not fully account for the effects of rain.
