Melting of Himalayan Glaciers Has Doubled in Recent Years
A new study is the latest and perhaps most convincing indication that climate change is eating the Himalayas’ glaciers, potentially threatening water supplies for hundreds of millions of people across much of Asia.

Scientists See Fingerprint of Warming Climate on Droughts Going Back to 1900
In an unusual new study, scientists say they have detected a growing fingerprint of human-driven global warming on global drought conditions starting as far back as 1900.

Drought: A Wide-Angle Picture
A new book, the second in a series of primers with the Earth Institute imprint, provides an interdisciplinary overview drought, bringing together many fields including climate science, hydrology and ecology.

As Oceans Warm, Microbes Could Pump More CO2 Back Into Air, Study Warns
A new study suggests bacteria may respire more carbon dioxide from the shallow oceans to the air as seas warm, reducing the deep oceans’ ability to store carbon.

Warm Autumn Winds Could Strain Antarctica’s Larsen C Ice Shelf
New research shows that the Larsen C ice shelf—the fourth largest ice shelf in Antarctica—experienced an unusual spike in late summer and early autumn surface melting in the years 2015 to 2017.

Deep-Sea Drillers Investigate Shedding of Antarctic Icebergs
Scientists are sailing to remote areas of the Southern Ocean to drill cores from the bottom that they hope will contain clues to past rapid changes in the Antarctic ice, and how it may react to warming climate today.

A Snowman’s Toils Under the Sun
One morning, a tiny snowman appears, seated on a bench near the corner of 112th Street and Broadway in New York City. Let’s take a picture every time we go by. Maybe we will learn something.

It’s Raining on the Greenland Ice. In the Winter.
Rainy weather is becoming increasingly common over parts of the Greenland ice sheet, triggering sudden melting events that are eating at the ice and priming the surface for more widespread future melting, says a new study.
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.
