    New Initiative to Focus on Climate and Extreme Weather

    Superstorm Sandy expert Adam Sobel is getting ready to launch a new initiative on extreme weather, thanks to a €250,000 two-year AXA Award in Climate and Extreme Weather he has just received from the AXA Research Fund.

  • Why Do We Run Hot and Cold on Climate Change?

    Why Do We Run Hot and Cold on Climate Change?

    People’s views on climate seem easily swayed, or in some cases manipulated, by daily weather. In a new study, researchers drilled into what goes on in people’s minds when they respond to these smaller-scale stimuli.

    New Predictions of Climate Change’s Impact on Agriculture

    Developing countries are more likely to see a drop in agricultural productivity and increased food prices due to climate change, particularly in tropical regions, according to a set of new studies out this week.

    Climate Change and the Future of Mono Lake

    Understanding the climate history of Mono Lake will help scientists understand the future impact of climate change. This is no esoteric question for Los Angeles, which depends in part on Mono Lake’s watershed for drinking water, green lawns, agriculture and industry.

    When the Sahara Turned to Sand

    The Sahara wasn’t always a desert. Trees and grasslands dominated the landscape from roughly 10,000 to 5,000 years ago. Then, abruptly, the climate changed. A study by Lamont-Doherty’s Peter deMenocal says it took just a few hundred years to happen.

    Q&A: Climate Change, Drought and the Future

    “One of the ways that climate change is going to manifest is through warmer temperatures. … What we are seeing, in line with our projections, is that even if you assume constant precipitation, the temperature effects are so large that it is going to dry things out. This is going to have really big impacts…

    Strange Bedfellows in the Climate Change Saga: Taiga to Tundra

    In the nine-hour drive on the great Dalton Highway to Toolik Field Station one starts out in the boreal forest, which is also called the “taiga,” but the forest eventually disappears. More accurately, trees disappear. Leaving Fairbanks, one drives through beautiful stands of spruce, birch, and aspen trees, but as one gets closer and closer…
