A grim climate lesson from the Canadian wildfires

Nowadays, the goal of most forest management in North America is to manage fire rather than always rush to extinguish it, to focus suppression efforts around denser human settlement and elsewhere to find ways to allow some burning. In the 20th-century model, firefighters parachuted in to snuff out flames, ultimately contributing to a continental buildup of the dry forest, grassland and scrub that fire experts casually call fuel. Now, to reduce it, fire scientists and forest ecologists try to cultivate more of what they call good fire.
