    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 Earth Shook, but It Wasn’t an Earthquake

    Last Thursday, thousands of people on the Eastern Seaboard felt the earth tremble. Seismologists at Columbia University’s Lamont-Doherty Earth Observatory quickly concluded it was not an earthquake, but a military exercise.

    In the Southern Ocean, a Carbon-Dioxide Mystery Comes Clear

    Twenty thousand years ago, low concentrations of carbon dioxide in the atmosphere allowed the earth to fall into the grip of an ice age. But despite decades of research, the reasons why levels of the greenhouse gas were so low then have been difficult to piece together. New research, published today in the leading journal…
