Snowstorms in a Warming World
On March 2 snowstorms hit the eastern seaboard, coinciding with a widely publicized protest against the coal industry in Washington DC . This garnered some attention, with Time noting the irony of people chanting about global warming while shivering in the cold and snow. One might wonder if a March snowstorm is inconsistent with a…

A Q+A on climate risk management in practice
I had the pleasure of interviewing Graeme Hammer from the Univ. of Queensland a while back about his experiences incorporating climate information into the decision-making process of farmers in Australia. Something he emphasized a number of times during our conversation: simply giving out additional information such as seasonal forecasts isn’t likely to solve any problems…

Dr. Larissa Back, a NOAA…

Giving new meaning to the word “hybrid”
Last week, we learned that the Obama EPA will conclude that carbon dioxide is an air pollutant as defined by the Clean Air Act (CAA). But a so-called endangerment finding on CO2 won’t lead to comprehensive CAA regulation, as I argued a few posts ago. Rather, the Obama administration will use the CAA as a…
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
