    War Against Natural Disasters: A Fight the Indian Military Can’t Win

    Ladakh’s glaciers are retreating, causing floods and threatening livelihoods. But a recent study reveals that disaster risk reduction is often slow or absent due to its status as a conflict and military-tense zone.

    Testing the Speed of Lava: What It Says about Escape Times & Mars

    Elise Rumpf’s lava flow simulations are yielding new details about the velocity of lava over different surfaces. They may also hold clues about the surfaces of other planets.

  • Mudslides: Forecasting Risk

    Landslides kill thousands of people each year but because they’re often triggered by earthquakes or heavy rains, the danger remains poorly understood. “In densely populated areas, landslides take no prisoners,” said Art Lerner-Lam, a scientist at Columbia University’s Lamont-Doherty Earth Observatory.  “They’ll wipe out an entire village at once. Even a small landslide can kill…

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.
