Carbon Pricing for the Climate: How It Could Work
Most economists and policy experts agree that the most effective and cheapest way to curb the carbon dioxide emissions that are warming the planet is to “put a price on carbon.” How effective are carbon taxes and cap and trade programs?

Forecasting Climate, with Help from the Baobab Tree
To improve climate forecasts, scientists study the complex interactions and mechanisms within the climate system. But they also need to hear from potential users of climate information, such as farmers, to get a better understanding of how people may use that information in their decision making.

Crushing Ice to Learn About Glaciers & Icy Moons
To understand how quickly ice from glaciers can raise sea level or how moons far across the solar system evolved to hold vast, ice-covered oceans, we need to be able to measure the forces at work. A new instrument designed and built at Lamont does just that.
AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
