Episode Details

Wildfires are exploding in North America and Europe this summer—Spain’s largest ever, Canada and U.S. burning more land than usual—with smoke choking cities. Yet globally, total burned land is at a record low. Why? Africa’s fire activity has plummeted over 25 years as more land is converted to farms and housing, limiting savanna fires. In Asia and the Amazon, fires are still used for land clearing, but shifting human populations alter global totals. Meanwhile, climate change is supercharging fires in the West: hotter, drier conditions, warmer nights, and longer seasons are making suppression harder. An incoming El Niño could worsen things in the tropics while possibly bringing rain to the U.S. West—only to fuel grass fires later. Adapting to this fireocalypse is no longer optional.
