    What’s in the Forecast and How Do We Know?

    The Earth Institute’s International Research Institute for Climate and Society makes probabilistic forecasts for rainfall and temperature for the next six months. How does it do this?

  • Rising Temperatures Lead to Increased Fire Risk in Indonesia

    Rising Temperatures Lead to Increased Fire Risk in Indonesia

    A new paper shows that rising temperatures have increased the risk of fires even during non-drought years in Indonesia, possibly making mild fire seasons in the country a thing of the past.

    Columbia, Princeton Scientists Share 2017 Vetlesen Prize

    S. George Philander of Princeton University and Mark A. Cane of Columbia University’s Lamont-Doherty Earth Observatory, who untangled the complex forces that drive El Niño, the world’s most powerful weather cycle, have won the 2017 Vetlesen Prize for achievement in earth sciences.

  • Two Who Enabled El Niño Forecasts Win 2017 Vetlesen Prize

    Warning Signs Now Applied Globally to Farming, Health, Water Issues

  • Forecasting Climate, with Help from the Baobab Tree

    Forecasting Climate, with Help from the Baobab Tree

    To improve climate forecasts, scientists study the complex interactions and mechanisms within the climate system. But they also need to hear from potential users of climate information, such as farmers, to get a better understanding of how people may use that information in their decision making.

    Learning from El Niño as La Niña Odds Rise

    Although El Niño is weakening, its ramifications continue to be felt around the world. Drought and resulting food insecurity is one of the major implications for southeast Asia, eastern and southern Africa, Central America and the Caribbean. Sixty million are in need of emergency relief today, according to the United Nations.

    Bleach Patrol: Turning Surfers into Scientists to Help Coral Reefs

    With coral bleaching spreading, a new project and app called Bleach Patrol is putting surfers, divers and snorkelers to work as citizen scientists, keeping an eye on the world’s coral reefs.

    El Niño and Global Warming—What’s the Connection?

    The United Nations has declared 2015 the hottest year since record keeping began. It was also a year marked by the occurrence of a “super” El Niño. Are the warming temperatures and El Niño connected?
