Irvine, California — The severity of California’s wildfires has rapidly increased over the last several decades as a result of human-driven climate change, resulting in accelerated tree losses during more intense wildfires, a study from University of California, Irvine and the University of Utah reveals. “As California’s climate has become warmer and drier, the severity of the average wildfire increased by 30 percent between the 1980s and 2010s,” said Jon Wang, a professor at the University of Utah. This means that for every acre of forest scorched by fire, the damages to tree canopy are considerably higher than what they were several decades ago. …The team wanted to find out how much of the rising tree cover loss in California is due to increases in total area burned, how much of the loss is due to increasing wildfire severity and how much is due to fire moving into new areas with denser forests.
