Increased wildfires are predicted to accompany ongoing climate change. Yet, little evidence exists supporting this hypothesis.

March 15, 2016One 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 are a kind of ground zero for this.

The Amazon Rainforest sprawls across more than 2 million square miles of South America, taking in carbon dioxide and releasing oxygen as “the lungs of the planet.” When they’re healthy, the world’s tropical forests and vegetation absorb up to 30 percent of the CO2 produced by human activities, but during droughts, that capacity falls off. To understand what that will mean as global warming produces more intense and frequent droughts, we need to understand the water and carbon cycles of the Amazon and how those cycles interact.
