    Photo Essay: Norwegian Rocks

    Geologist John Templeton recently spent a year on Norway’s west coast trying to understand how rocks now at the surface made an epic journey deep into Earth’s interior and back during the growth and subsequent collapse of the ancient Caledonian mountains.

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
