Obi Kaufmann considers the coming of the modern megafire and many deeply entrenched misconceptions about California’s land, in an excerpt from “The State of Fire.” There was always going to be a period of reckoning—with California’s colonial legacy, with the state’s history of fire management, with the practices of extractive industries, with our patterns of land development—and in the past 20 years, it has arrived. California has entered an era of megafire. In accordance with the National Interagency Fire Center, the word megafire refers to any fire that is larger than 100,000 acres (156 square miles). Eighteen of the 20 largest wildfires in the past 200 years have occurred since the year 2003.
