    Q&A: Climate Information for Food Systems

    Scientists at the International Research Institute for Climate and Society are studying how much climate plays a role in the global food supply, identifying food system vulnerabilities in specific areas, using new kinds of climate information in agricultural modeling, and more.

    Q&A: Using Farmers’ Perceptions as Data

    Researchers at IRI have been developing index insurance, which would provide a safety net for farmers who experience devastating climate events such as droughts and floods that severely impact their crop yields.

    The Latest in Subseasonal Climate Prediction

    Until recently, predicting rainfall and temperature at the subseasonal timescale (i.e. between two weeks and three months) was considered impossible. That’s beginning to change.

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.
