Study Reveals How Gas Bubbles Shaped Kīlauea’s 2018 Lava Flow
New research shows that gas bubbles played a central role in controlling how fast and far the lava traveled, and that lava flow models need to account for bubbles to more accurately forecast where lava will stop.
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.
