    Expanding Our Vision Brings the Big Picture Into Focus

    1500 feet above the ground surface is where our suite of instruments normally operates, but for this flight we are taking them up higher, much higher, in fact over 20 times our normal range to 33,000 feet. Our flight plan is to repeat lines surveyed in a previous years by NASA’s Land, Vegetation Ice Sensor…

    Next, Imbabura

    Today was a much longer climb up Imbabura, passing through more páramo until reaching our first Polylepis trees. Conveniently, they were marked by a little wooden sign. These are the trees that I hope to sample next week on Chimborazo.

    Climbing Fuya Fuya

    After trudging through the paramo, our route becomes a high-altitude scramble on an exposed rocky granite spine with sheer drop-offs on either side. The surge of adrenaline keeps our minds off the thin air.

    Arctic Archipelago: Ground Zero For Climate Change

    Summer temperatures on the archipelago of Svalbard, 400 miles north of Norway, are now higher than at any other period in the last 1,800 years, according to a new study in the journal Geology.

    Preparing for Chimborazo

    I am staying with a friend’s family in Quito, Ecuador’s capital city, and tomorrow will meet up with my climbing partner, Pablo Puruncajas, to prepare for our expedition. I am here to collect tree ring samples and put up a weather station on Chimborazo, Ecuador’s tallest peak, to provide climate data about this region, which…

  • The Missing Piece in Sustainable Peace

    The Missing Piece in Sustainable Peace

    We know very little about what “peace” is (and what it isn’t), the conditions that promote it, the motives that drive people to work for it, how to measure it, and how to build a climate and infrastructure that sustains it. Why? Because we don’t study peace. We study war, violence, aggression and conflict—and peace…

    A Prescient Voice on Sandy: Suddenly Everyone Is Listening

    For much of the last decade, Klaus Jacob warned of New York’s vulnerability to severe flooding in a major storm. Four days after the storm that crippled New York and New Jersey and swamped his own home along the Hudson River, Jacob reflected on Sandy’s lessons and what comes next.

    Why U.S. Politics are Stuck – and a Possible Way Out

    In this recent TEDx talk in Miami, Professor Peter T. Coleman, chair of the Advanced Consortium on Cooperation, Conflict, and Complexity (AC4) at The Earth Institute, explains why politics in the United States are more deadlocked and polarized today than they have been since the end of the U.S. Civil War, and what our next…

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.
