California wildfires will become more severe in the future as warmer temperatures give way to drier summers, a decrease in the amount of snow at higher elevations despite above average rainy seasons and, possibly, because humans are too good at putting blazes out.
Improvements in suppressing forest fires, rather than letting them run their natural course, has led to forests bursting with underbrush and crowded trees, according to a study published Monday in the Proceedings of the National Academy of Sciences.
Researchers reconstructed 400 years of climate data to determine what causes wildfires in California and found many of the elements that would have pointed to a strong, wet winter would have led to a weaker wildfire season.
But that has not been the case recently as the last few years of insurmountable wildfires in California has been any indication.
