400 ppm World, Part 2: Rising Seas Come with Rising CO2
Every indication is that thermal expansion will not dominate rates of sea-level rise in the future. As Earth’s climate marches toward equilibration with present-day CO2 levels, the climate will continue to warm. And this warming threatens the stability of a potentially much, much larger source for sea-level rise — the world’s remaining ice sheets.

The Microgrid Solution
Last October, Superstorm Sandy provoked widespread frustration and fear after it left more than 7.5 million people in the New York Metro area without power. In the hardest hit areas, outages lasted two weeks or more. These failures led many observers to wonder if America’s aging electrical grid was up to dealing with emerging climate…

A Library of Giant Landslides
A new method for detecting big landslides is allowing scientists to understand the dynamics of these elusive events almost instantly, without traipsing to remote mountains or scrambling up rugged peaks months, or even years, later. In a recent study in the journal Science, Göran Ekström and Colin Stark, geophysicists at Columbia University’s Lamont-Doherty Earth Observatory,…

Where’s My Seasonal Tornado Forecast?
Tornadoes, derechos and other violent storms can kill hundreds each year and cause billions in damages. How well can we predict them? How will climate change influence their occurrence? Experts from around the country discussed these issues at a recent workshop.

The Law of Drowning Nations
Sea levels are inching up year by year, and by various projections could be two to six feet higher by 2100—enough to make some small, low-lying island nations uninhabitable, or simply to wipe them off the map. What rights will citizens have to live elsewhere; in fact, will these entities actually still be nations, with…
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
