Flaring Gas: How Not to Waste a Valuable Resource
Every year, oil fields around the globe burn, or “flare,” an estimated 3.5 percent of the world’s natural gas supply. The gas is produced alongside oil and must be disposed of during the production process. Eliminating flaring would reduce CO2 emissions by as much as removing 77 million cars from the road. Moreover, the flaring…

Almost Home, with Another 7 Million Years of Climate History
Science at sea isn’t easy, but the benefits are huge, writes Sidney Hemming in her final post from a two-month expedition that collected millions of years of climate history in the deep-sea sediment from off southern Africa.

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…
