  • Climate Underpinnings of East Africa Drought

    Climate Underpinnings of East Africa Drought

    Watch a video interview of climate scientist Brad Lyon on the conditions leading up to the ongoing drought in East Africa. He says there’s a chance of La Niña forming later in the year, which could have devastating consequences for a region already plagued by widespread famine.

  • The Role of Drought in the Horn of Africa Famine

    The Role of Drought in the Horn of Africa Famine

  • Climate information and disasters: two interviews

    Jan Egeland and Madeleen Helmer talk about the value of forecasts in disaster preparation.

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

    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…
