Five of the 10 largest wildfires in state history have occurred since August. Beyond their size, how do the scope and devastation of this year's fires compare to previous wildfire seasons in California? The previous record was set in 2018 when deadly wildfires destroyed 1.67 million acres (2,609 square miles or 6,760 square kilometers). The August Complex, burning in the Coast Range between San Francisco and the Oregon border, surpassed 1 million acres, another record. Gavin Newsom said the amount of land scorched by the August Complex is larger than all the recorded fires in California between 1932 and 1999.

SAN FRANCISCO – Deadly wildfires in California have burned more than 4 million acres (6,250 square miles) this year — more than double the previous record for the most land burned in a single year in the state. California fire officials said the state hit the astonishing milestone Sunday with about two months remaining in the fire season. The previous record was set two years ago when wildfires destroyed 1.67 million acres (2,609 square miles). Cal Fire said in a statement Sunday that there have been more than 8,200 wildfires since the start of the year that have burned "well over 4 million acres in California." Numerous studies have linked bigger wildfires in America to climate change from the burning of coal, oil and gas.
