California’s Biggest Wildfires From 2012 to 2022

California’s wildfires have caused so much devastation throughout the past decade. All throughout the state, firefighter efforts have been absolutely exhausted. Just in 2020, approximately 9,917 fires had burned 4,397,809 acres, the most acreage recorded in modern history. Most of the acres burned during the August Complex Fire.
