  • R.I.P. La Niña

    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?

    How to reduce weather risk (and make a little green)

    People understand that weather can affect certain markets — especially energy prices and other commodities — but its impact on portfolios more broadly might surprise. Just last week, a new study was released that estimated $485 billion of annual weather-related economic impact in the United States alone. Another calculated the effect at nearly 10 times that amount…

    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?

    Informing Farmers and Combating Drought in Mali

    A new case study authored by scientists at Mali’s national meteorological service and the International Research Institute for Climate and Society chronicles a success story of linking farmers to climate information in response to the 1972-1984 drought.

    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.

  • Insuring the World’s Poorest Farmers

    Insuring the World’s Poorest Farmers

    Index insurance could help small-scale farmers build wealth and cope with climate change, but more accurate weather and climate data is needed for index insurance to catch on, writes Daniel Osgood, a scientist at Columbia University’s International Research Institute for Climate and Society (IRI). In a new piece in Nature Geoscience, Osgood and colleagues outline…

  • Improving Climate Prediction in Africa

    Improving Climate Prediction in Africa

    Africa lags the developed world in weather stations but still produces a surprising amount of data. Too bad few people are using it. Scientists at Columbia University and a growing number of others—among them Bill Gates and the charity arm of Google—are pushing to open Africa’s climate archive to the world by making it free.…
