Climate May Quickly Drive Forest-Eating Beetles North, Says Study

Over the next few decades, global warming-related rises in winter temperatures could significantly extend the range of the southern pine beetle, one of the world’s most aggressive tree-killing insects, through much of the northern United States and southern Canada, says a new study.

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 climate change does catch up with them, as expected.

Williams studies how forests react to changes in climate, and the Ozarks’ deeply dissected hills and hollers—what some might refer to as typical hillbilly country—are a kind of ground zero for this.
