    Has Global Warming Stalled? How Long Will It Last?

    Climate Scientist Lisa Goddard talks about what may be behind the recent slowdown in global warming, and some of the nuances of predicting just how the climate will change.

    Fears of a Double Dip…La Niña

    You’d be forgiven for thinking its 2008 and not just because of the economic uncertainty. Is there a dreaded double dip La Niña in store, too?

    R.I.P. La Niña

    La Niña, we hardly knew ye. This year’s iteration of the climate phenomenon nearly set records for strength and riled up world weather for nine months. Now it’s dead. What’s next?

    La Niña Still Hanging On

    IRI’s latest climate briefing shows a weak La Niña still hanging around. The big question is what will happen next?

    La Niña Begins to Weaken

    The current moderate-strength La Niña is now weakening and is expected to dissipate by late spring, said Tony Barnston, the lead forecaster at the International Research Institute for Climate and Society, which holds a monthly climate briefing. Early February showed the first easing in strength of the cool sea-surface temperatures in the central and eastern…

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
