Earth’s Current Warmth Not Seen in the Last 1,400 Years or More, Says Study
Fueled by industrial greenhouse gas emissions, Earth’s climate warmed more between 1971 and 2000 than during any other three-decade interval in the last 1,400 years, according to new regional temperature reconstructions covering all seven continents. This period of manmade global warming, which continues today, reversed a natural cooling trend that lasted several hundred years, according…

Plumbing the Deep Ocean Floor
A video profile of the Lamont-Doherty Core Repository—the world’s largest collection of deep sea sediments, some as old as 100 million years. The 19,000 cores, largely collected by Lamont’s own research vessels, are a central resource for the global scientific community, which uses them for studies of earth’s past and current environment, especially in regard…

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
