    But Warming Now May Be Tipping Region Into Unparalleled Drought

  • Climate Scientist Is First Woman to Win Geology’s Storied Wollaston Medal

    A climate scientist who has suggested how mountain building can lower Earth’s thermostat and why ice ages sometimes wax and wane at different speeds has been awarded one of geology’s oldest and most coveted prizes: the British Wollaston Medal. The first woman to win a Wollaston in the prize’s 183-year history, Maureen Raymo, a researcher…

  • Has Global Warming Stalled? How Long Will It Last?

    Has Global Warming Stalled? How Long Will It Last?

    Climate Scientist Lisa Goddard talks about what may be behind the recent slowdown in global warming, and some of the nuances of predicting just how the climate will change.

    Global weirding?

    Mountains of snow line the street, And some days I envy a beard. Ask any shoveler you meet – The weather this winter is weird!

    2013 Ranks in Top 10 Warmest Years

    Last year was one of the warmest on record, according to analyses of global temperature data by NASA and NOAA. Both federal agencies placed 2013 among the top 10 warmest years since records began in 1880, continuing a longer-term trend of global warming.

    Why Do We Run Hot and Cold on Climate Change?

    People’s views on climate seem easily swayed, or in some cases manipulated, by daily weather. In a new study, researchers drilled into what goes on in people’s minds when they respond to these smaller-scale stimuli.

    The Arctic’s Secret Garden

    Lamont-Doherty Earth Observatory marine biologists Craig Aumack and Andy Juhl spend a month each spring in Barrow studying the algae dwelling in and under the sea ice. Their goal is to learn more about the different species of algae that compose these communities and their role in the Arctic marine food web.

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.
