  • Students Share Findings from Global Research

    This April over fifty students shared the results of their respective research projects with the rest of the Columbia community as part of the 2013 Student Research Showcase. While all within the field of sustainable development, research topics ranged from climate change to community development and included work from across the world.

    “You can do math on excel?” I ask. I immediately imagine a face-palm response, but Dario, one of my advisors, is nice enough to hide it. I’ve collected tree core samples, I’ve prepared them and cross-dated them. Now what? Oh, right. The Science.

    A video profile of the Lamont-Doherty Core Repository—the world’s largest collection of deep sea sediments, some as old as 100 million years. The 19,000 cores, largely collected by Lamont’s own research vessels, are a central resource for the global scientific community, which uses them for studies of earth’s past and current environment, especially in regard…

    Singing the Blues About Water Scarcity

    Otis Redding sang “you don’t miss your water ’til your well runs dry” in 1965 about pining for a lost love. Last week, Climate and Society founder and Lamont-Doherty Earth Observatory scientist Mark Cane reprised it with a much different, more literal focus: water scarcity in the 21st century.

  • NASA’s Jim Hansen to Retire

    James E. Hansen, director of NASA’s Goddard Institute for Space Studies (GISS) and an adjunct professor at Columbia University’s Earth Institute, has announced he will retire as director of GISS this week to devote more time to his campaign to cut global carbon emissions. “Jim Hansen is a one of the true giants of climate…

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.
