    Heat Has Decoupled French Grapes from Old Weather Patterns

  • Scientists Say Many Plants Don’t Respond to Warming as Thought

    From Tundra to New York Exurbs and Tropics, New Data Lowers Estimates of Carbon Release

    Where Will Sea-Level Rise Hurt the Most?

    A study out yesterday says that the lives of up to 13 million people in the United States may be disrupted by sea-level rise in the next century. But another study says that while much hard infrastructure like houses, piers, seawalls and roads may have to be kissed goodbye, some 70 percent of natural landforms…

    Photo Essay: High in the Hills, Climate May Challenge Forests

    Forests in the south-central United States are some of the country’s most productive and diverse. They also sit in a warming “hole”—an area where the progressive rise in temperature affecting most of the continent hasn’t yet taken hold. A team from Columbia University’s Lamont-Doherty Earth Observatory is studying how these forests might shift—or even disappear—when…

    How Will Shifting Climate Change U.S. Forests?

    One foggy spring morning just after a hard rain, Park Williams was tromping through the woods deep in Arkansas’ Ozark Mountains. Toiling down a steep slope, he supposedly was keeping a simultaneous eye out for rattlesnakes, copperheads, poison ivy and big old trees. Williams seemed mostly focused on the trees, though; attention to the other…

  • The Technological World and the Risk of Nuclear Power

    The modern economy and our way of life depend on new and advancing technology. It especially depends on energy technology.
