Subglacial Lakes in Antarctica Found to Be More Active Than Previously Thought
A new study finds that a system of lakes under Thwaites Glacier have undergone large drainage events, highlighting underestimates in the melting rate of the glacier.

Nick Frearson Designs Devices for Earth’s Most Extreme Environments
An engineer at Lamont-Doherty, Frearson builds instruments that help scientists collect vital data in Antarctica, the deep sea, and at the top of volcanoes.

Damage Uncovered on Antarctic Glaciers Reveals Worrying Signs for Sea Level Rise
A new study has revealed extensive new damage to two major Antarctic glaciers that creates the conditions needed for ice shelf collapse.

Stability Check on Antarctica Reveals High Risk for Long-Term Sea Level Rise
The warmer it gets, the faster Antarctica will lose ice, and at some point the losses will become irreversible. That is what researchers say in a new cover story in the leading journal Nature, in which they calculate how much warming the Antarctic Ice Sheet can survive.

Deep Channels Linking Antarctic Glacier’s Underside to Ocean Could Hasten Melting
Newly discovered seabed channels beneath the Thwaites Glacier may be pathways for warm ocean water to melt the ice’s undersides and contribute to sea level rise.

Antarctic Ice Shelves Vulnerable to Sudden Meltwater-Driven Fracturing, Says Study
A new study says that many of the ice shelves ringing Antarctica could be vulnerable to quick destruction if rising temperatures drive melt water into the numerous fractures that currently penetrate their surfaces.

How Ice Scouring in the Antarctic Disrupts Ecosystems
A recent study sheds light on how different types of species are affected by calving icebergs that tear apart the seafloor.

Refining Projections of Antarctic Ice Loss and Global Sea Level Rise
Research by Center for Climate and Life Fellow Pierre Dutrieux will lead to greater understanding of the West Antarctic Ice Sheet’s future stability and associated sea level rise.

Ozone Treaty Stopped Jet-Stream Drift in Southern Hemisphere
Researchers long ago predicted that the 1987 Montreal Protocol, banning ozone-depleting gases, would reverse a worrisome trend in Southern Hemisphere winds. A new study shows they were right.
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.
