Two survivors of California fires compile a guide for living physically, mentally, and emotionally amid ecological destruction. When warm temperatures, low humidity, and strong winds combine they produce an increased risk of fire danger called a "red flag warning"—a common event in Northern California. Through essays and interviews, Red Flag Warning sheds light on how wildfire impacts our communities and offers wisdom on living with fire from Indigenous Californians, community organizers, mental health care workers, environmentalists, fire analysts, sustainable loggers, parents, and more. The collection explores the ways these fires take root and impact rural and urban Northern California, it examines our relationships to place and community and to understand the importance of mutual aid, organizing, community care, land stewardship, and resilience. Red Flag Warning covers the stories not frequently found in the often disaster-porn obsessed media and exposes what is lost in the news written by parachute journalists. Readers are invited to examine what fire can and does mean to them, what it means for us to reimagine the world, to prepare for the worst, and to examine flames through different lenses.
