    Photo Essay: High Desert, Deep Earth

    In the Arabian peninsula nation of Oman, geologists are studying the Hajar mountains–a range containing rocks that have been thrust up from the deep earth. Accessible to humans in only a few places on earth, these kinds of rocks offer clues to the planet’s deep history–and possible ways that natural processes may be harnessed to…

  • Students Work on Net Zero Energy to Adaptation Planning Projects

    By Noah Morgenstein This past May, seniors in the Capstone Workshop in Sustainable Development delivered their final presentations to fellow students and faculty at Columbia University. The workshop is a required course for students in the Sustainable Development major or special concentration. Unlike traditional courses, the workshop requires students to work collaboratively on a client project…

  • The Microgrid Solution

    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…

    Of Cow Dung, Cook Stoves and Sustainability in Practice

    When the Environmental Defense Fund asked me to measure how biogas cook stoves were changing the lives of farmers in rural India, there wasn’t a word in that question with which I was comfortable. Having just graduated from the Undergraduate Program in Sustainable Development, I had never done fieldwork; and the concept of a biogas…

    Climate and Conquest: How Did Genghis Khan Rise?

    Eight hundred years ago, relatively small armies of mounted warriors suddenly exploded outward from the cold, arid high-elevation grasslands of Mongolia and reshaped world geography, culture and history in ways that still resound today. How did they do it?

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
