    IRI to develop climate adaptation tools to help farmers in South and Southeast Asia

    A new two-year climate change initiative, led by the International Research Institute for Climate and Society aims to help farmers in Indonesia, the Lao People’s Democratic Republic and Bangladesh reduce their vulnerability to climate risks.

    The Law of Drowning Nations

    Sea levels are inching up year by year, and by various projections could be two to six feet higher by 2100—enough to make some small, low-lying island nations uninhabitable, or simply to wipe them off the map. What rights will citizens have to live elsewhere; in fact, will these entities actually still be nations, with…

    A New Primer on Sea Level

    The threat of sea-level rise–actually, its ongoing reality–has been on many more minds since New York and surrounding areas were walloped during Hurricane Sandy by a record-high storm surge, abetted by a water level that has risen steadily over the last century. That level will keep rising if climate keeps warming, and so, probably, will…

    Making Sense of Climate’s Impact on Food Security

    From warmer temperatures to natural disasters such as flooding and drought, changing patterns of climate are having billion-dollar impacts on our food-growing systems. But scientists are struggling to find ways to measure and predict what may happen in the future—and to translate that into policies to help feed a bulging world population.
