Rain May Increase Ocean Carbon Uptake More Than We Thought
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.

From Landslides to Lava: A Journalism Student’s First Lamont Open House
Oobleck, seismology and seafloor sediments bring Earth science alive during the observatory’s annual public celebration.

The Next Warning Must Reach People Before the Water Does
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.

October Research Roundup: Select Papers
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.

Two Lamont Scientists Celebrate Marie Tharp’s Hall of Fame Induction—and Carry Her Legacy Forward
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.

How a Massive Ancient Ice Shelf Stabilized Glaciers—and What It Means for Antarctica
New research could lead to more accurate predictions about how quickly Antarctic glaciers might retreat and raise sea levels.

Climate Change Stopped the Next Ice Age
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.

Highlights From the 2026 Open House at Lamont-Doherty Earth Observatory
More than 2,500 visitors explored hands-on activities, lectures and installations at Lamont’s campus on Saturday, October 17.
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.
