    Climate Forecasting: Oceans, Droughts, Climate Change and Other Tools of the Trade

    At the International Research Institute for Climate and Society’s monthly climate briefing, talk often focuses on the role that El Niño or La Niña play in driving global climate. With the collapse of La Niña last month, though, IRI’s forecasters now have to rely on different tools to offer forecasts for the coming year. That’s…

    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?

    To Burn, or Not to Burn

    A new report by the World Resources Institute showcases IRI’s efforts to get decision makers in Indonesia to change their fire policy, so that it was based on seasonal climate information.

    A return to near normal conditions in the Pacific doesn’t mean there aren’t other interesting climatic phenomenon afoot.

    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…

    La Niña Rolls On

    The current moderate-to-strong La Niña is expected to continue through at least the middle of spring, said forecasters at the International Research Institute for Climate and Society’s monthly climate briefing.

  • El Niño Begins to Dissipate

    Though weak El Niño conditions still exist, it appears that the climatic phenomenon that developed over the course of last summer has finally begun to dissipate. As reported earlier, El Niño is the name given to sustained sea surface temperature (SST) anomalies greater than 0.5°C across the central tropical Pacific Ocean. It is the warm…

  • Top misconceptions about El Niño and La Niña

    Forecasts by the International Research Institute for Climate and Society and other institutions show that a weak El Niño has developed in the equatorial Pacific, and is likely to continue evolving with warmer-than-normal conditions persisting there until early 2010. What exactly is this important climate phenomenon and why should society care about it? Who will…

Recent record-breaking heat waves have affected communities across the world. The Extreme Heat Workshop will bring together researchers and practitioners to advance the state of knowledge, identify community needs, and develop a framework for evaluating risks with a focus on climate justice.
