    Rivers and the Road

    We spent a day on the islands (chars) in the Brahmaputra River seeing the geology and talking to the residents. Then after an evening of feasting and dancing in our new Saris and lungis, we hit the road for the trip to the Sundarbans.

    Class Trip – to Bangladesh

    To help my students in a class on hazards of Bangladesh better understand the country, I am taking them there to experience Bangladesh for themselves.

    Plugging the Leaks in Climate Models

    Independent quality controls for climate models are crucial for the quality of future climate change predictions. Not all models are equally good and should be utilized in climate impact studies for such things as crop yield and hydrology that are produced for far-reaching decision-making.

    Ocean Acidification: Geologic Record Adds New Warning

    A new study in Science finds that the oceans may be acidifying faster today from industrial emissions than they did during four major extinctions in the last 300 million years when carbon levels spiked naturally.

    Watch an Antarctic Iceberg in the Making

    What does a glacier about to spawn an iceberg the size of New York City look like? A new animation from NASA flies you through the 19-mile crack that is slowly tearing Antarctica’s Pine Island Glacier apart.

    Fixing Climate: Beyond Carbon Dioxide

    Climate scientists at a meeting of the American Association for the Advancement of Science this week were elated to hear that the United States and five other countries had agreed to work toward cutting pollutants other than carbon dioxide thought to cause about a third of current human-influenced global warming. After all, many of them…

    Did the Oceans Influence Human Evolution?

    Scientists often invoke climate as a possible factor in human evolution; but only recently have they developed the ability to get enough information about past climates and related fossil evidence to see any details. A half-dozen leading paleontologists and climate scientists discussed recent advances in a symposium this week at the annual meeting of the…

    Extraordinary Support for Unprecedented Global Challenges

    The Earth Institute’s annual donor report for fiscal year 2011 is now available in an interactive digital format. We remain committed to finding extraordinary support to unprecedented global challenges, many of which are outlined in this report. We have highlighted some of our innovative projects in research, policy, and education, as well as the partnerships…

    Scientists Drill 2 Miles Down to Ancient Lake Vostok

    Russian scientists this week finished penetrating more than two miles through the Antarctic ice sheet to Lake Vostok, a huge freshwater lake that has been buried under the ice for millions of years. But they won’t know what they’ve found until next year.

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.
