Dying Reefs Bigger Threat to Coasts Than Rising Seas, Study Says
If coral reefs continue to degrade, waves on coastlines may substantially increase, leading to greater coastal erosion.

Why Do Floods Sometimes Happen on Sunny Days?
Some towns and cities can get soaked even when the skies are dry—and these so-called sunny day floods are on the rise thanks to climate change.

Giant Boulders on Bahamas Coast Are Evidence of Ancient Storms and Sea Level, Says Study
A new study says that storms of intensities seen today, combined with a few meters increase in sea level, were enough to transport coastal boulders weighing hundreds of tons more than 100,000 year ago.

Ice Sheets May Melt Rapidly in Response to Distant Volcanoes
A study of ancient eruptions shows modern ice sheets could be vulnerable.
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.
