Such burns release less carbon dioxide than wildfires, scientists find The use of prescribed burns to manage western forests may help the United States reduce its carbon footprint. Results of a new study find that such burns, often used by forest managers to reduce underbrush and protect bigger trees, release substantially less carbon dioxide emissions than wildfires of the same size. "It appears that prescribed burns can be an important piece of a climate change strategy," says Christine...
