  • Climate Change Could Drive Vast Human Migrations

    Displacements Already Underway, Says Report

  • Climate and Meningitis in Africa

    We hear a lot about the impact of AIDS, tuberculosis and malaria in Africa. But if you’re keeping track, you may as well add bacterial meningitis to the list of nasty diseases that plague the continent. Bacterial meningitis is an infection of the thin lining that surrounds the brain and the spinal cord, known as…

  • Health people, meet climate people!

    Since Monday, 12 public-health professionals and climate scientists from ten countries have been at Columbia University’s Lamont campus to learn how to use climate information to make better decisions in health-care planning and disease prevention. They’re taking part in the second Summer Institute on Climate Information for Public Health, organized by the International Research Institute…

  • Adaptive Strategies in Managing Climate Change Risk

    With the threat of rising sea level due to thermal expansion (water increases volume as it gets warmer) and melting of land-based ice (such as glaciers and polar ice sheets), coastal cities are planning ways to minimize the impacts of flooding on city infrastructure. The Thames Barrier (pictured) is one such engineering solution. It is…

  • Dam Break in Northeast Brazil: Can We Blame Global Warming?

    Nordeste, the driest region in Brazil, has been castigated by heavy rainfall in the last two months. Yesterday a dam broke in the state of Piaui killing at least four people. The video below shows a partial bridge that collapsed after the dam break. The media shows every day more and more news about natural…

    International Research Institute Focuses on Practical Adaptations

  • Climate Change and CO2 Uptake

    The Keeling Curve, a record of rising atmospheric carbon dioxide since 1958, is one of the most recognizable images in modern science. Despite its ubiquity, this iconic graph tells only half – or, more precisely, 57% – of the story. That’s because the other 43% of cumulative anthropogenic emissions haven’t made it to the atmosphere…

  • Down by the River, Running Out of Water

    Too little water for too many people is a growing problem in poor countries–and in thriving suburban Rockland County, N.Y., just north of New York City. A new website, Water Resources in Rockland County, lays out the case, and neatly puts it into global context. The site is run by the Earth Institute’s Center for International Earth Science Information Network…

  • Swine flu, climate change, and the future of infectious diseases

    Since the first cases of swine flu, or H1N1, were reported in April, public health organizations, governments, media and the general public have spent much time and energy trying to understand and contain the virus. Responses have ranged from the serious (like the WHO’s declaration of a phase 5 pandemic alert) to the ridiculous (like…

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.
