Forestry professor David B. South of Auburn University says that atmospheric carbon dioxide concentrations have nothing to do with the amount and size of wildfires. It’s largely forest management that determines the number and size of wildfires, not global warming. “Policy makers who halt active forest management and kill ‘green’ harvesting jobs in favor of a ‘hands-off’ approach contribute to the buildup of fuels in the forest,” South told the Senate Environment and Public Works Committee on Tuesday. “This eventually increases the risk of catastrophic wildfires,” South said.
‘Data suggest that extremely large megafires were 4-times more common before 1940,” South said, adding that “we cannot reasonably say that anthropogenic global warming causes extremely large wildfires.’
