A new study shows that some of Yellowstone National Park’s forests may be at a climate tipping point, and could be replaced by grassland by the middle of this century.

A new film how India’s fast-expanding road networks is fragmenting the few remaining refuges of many endangered creatures. The results are hard to watch.
International development increasingly recognizes that governance, economic growth, health, and human well-being are inextricably linked—multisectoral programming is the order of the day. But conservation too often gets left out of the picture.
Researchers survey the damage to Puerto Rico’s forests in the aftermath of Hurricane Maria.
Ecologist Maria Uriarte investigates the effects of Hurricane Maria on the forests of Puerto Rico, and how long-term climate change may affect them.
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.
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.
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 stuff was just slowing him down. 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.
Seeing the Amazon’s Future Through the Fog
Scientists have developed a new approach to modeling the water and carbon cycles in the Amazon that could lead to better climate forecasts and improved water resource management.
Forests are a vitally important habitat for much of the world’s terrestrial biodiversity. During this class you will learn key issues in forest ecology and management through an all-day field trip to Black Rock Forest, and study how pathogens and other invasive species affect forest structure and function.
