Climate Services: Science=Credibility
It’s terribly important that those who provide climate services are backed up by science and most importantly, link with and understand the problems of the user community. – says John Zillman, former president of the World Meteorological Organization, in the fourth in a series of video interviews.
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
