The Measure of a Man: Jerome M. Paros ’63GSAS’ Life of Invention and Philanthropy
Jerry Paros’ inventions have improved the measurements of geophysical phenomena such as tsunamis, and enhance our ability to understand the complex earth, air and ocean processes that produce climate 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.
