A new study focuses on the effects of deforestation in the Amazon and the risks posed by fire and drought. Logging can exacerbate the problem by making room for quick-burning grasses and allowing warmer air to move in, the study suggests. "It's only in the past couple of decades that fire has even been recognized as a major disturbance in Amazon forest," said Jennifer Balch, an assistant professor of geography at Penn State University. "Fire scientists are catching up with a phenomenon that's happening so quickly as a result of frontier expansion and land use changes."
