    Climate May Make Some Regions ‘Uninhabitable’ by End of Century

    The global trend toward hotter summers could make parts of the Middle East and tropics “practically uninhabitable” by the end of the century, new research published this week contends.

    Globally, the tool estimates at least 11 inches of sea level rise this century with ambitious efforts to lower greenhouse gas emissions and as much as 52 inches if greenhouse gas emissions continue to grow unchecked.

    A Prize-Winner Explains His Work

    Nicolás Young studies glaciers and ice sheets, and how they’ve changed in the past. His work earned him the Blavatnik Award for Young Scientists last fall, which came with a $30,000 prize. You can hear him talk about his research in this new video, produced by the Blavatnik Family Foundation.

    That change would have affected the monsoons, today relied on to feed over half the world’s population, and could have helped tip the climate system over the threshold for deglaciation.

    What Does El Niño Mean, in 3.4 Seconds

    Scientists at the International Research Institute for Climate and Society took a moment from their work (a very brief moment) to answer the question, “What does El Niño mean?”

    It’s Beginning to Look Not a Lot Like Christmas

    Much of the eastern two-thirds of the United States was balmy on Christmas Day, with high temperatures more than 20°F above average from Texas to Maine. According to NOAA, 789 daily high temperature records were tied or broken on Christmas Eve and Christmas Day in the continental United States. What’s behind this unusual weather?

    Sea Level Rise: How Much, How Fast?

    By studying modeled climate evidence from the last interglacial period, the team concluded that the warming going on today risks setting off “feedbacks” in the climate system.

    World Wildlife Fund, Earth Institute Form New Partnership

    The World Wildlife Fund will collaborate with the Earth Institute’s Center for Climate Systems Research to advance adaptation to the impacts of climate change around the globe. The partners will create new ways of generating climate risk information and embedding it into the World Wildlife Fund’s conservation and development planning, policies and practice.
