Geology Marches Forward
For most of our drive, I stare out the window and ask Mike questions: “Is that a glacial moraine?” and “How tall were the Andes originally?” and “Why are those sediments white?” He can respond to a stunning number of these questions. I love being around field geologists; the way they make sense out of…

More Dust, Lago Potrok Aike
Jay and Barbara took off this morning in a rugged-looking truck while Mike and I followed in a Honda CR-V that looks more appropriate for Route 9W than Patagonia’s gravel roads. We’re hopeful that nothing terrible will go wrong. Wish us luck! I was totally entranced by the geomorphology of this place: I must have…

A “Legally Binding” Climate Agreement: What Does it Mean? Why Does it Matter?
The term “legally binding” has become a touchstone of sorts in international climate policy. The Copenhagen Accord taken note of by the fifteenth Conference of Parties (COP) under the United National Framework Convention on Climate Change in December 2009 is not legally binding. Heads of state and activists alike call for a legally binding agreement…

Some Thoughts About Dust, Rio Gallegos
I’ve been to Stewart Island, off the southern tip of New Zealand, but I’m pretty sure this is the furthest south I’ve been. Cool! We’re here in Rio Gallegos. We’ve just rendezvoused with Dr. Jay Quade, a geologist from the University of Arizona, and his wife Barbara. We’ve got two cars, a bunch of boxes…

New Dept of Interior Water Strategy
“The federal government’s existing water policies and programs simply aren’t built for 21st century pressures on water supplies,” Salazar said. “Population growth. Climate change. Rising energy demands. Environmental needs. Aging infrastructure. Risks to drinking water supplies. Those are just some of the challenges.”

Assessing Continuing Quake Risks, by Sea
This week U.S. and Haitian scientists will start a 20-day research cruise off Haiti to address urgent questions about the workings of the great Jan. 12 earthquake, and the possibility of continuing threats. They hope to gather sonar images, sediments and other evidence from the seafloor that might reveal hidden structures, how they have moved,…

Economist says climate change countermeasures make financial sense
In a New York Times article Feb. 20, Robert H. Frank, an economist at the Johnson Graduate School of Management at Cornell University, argues that acting to stop climate change makes economic sense.

Arrival: Buenos Aires
We arrived in Argentina after a night in the air—maybe the first time I’ve ever gotten a (nearly) decent night’s sleep on a plane. We took a taxi across the city. It’s hot and flat, and our taxi driver explains that they’ve had torrential rains for several weeks; all the lowlands alongside the highway are…

Scientists Sail to Assess Haiti Quake Threat
Research Ship Will Image Faults, Seek Signs of Hidden Dangers
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
