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…

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.
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
