It’s been smoky this season. Based on research from Michael Goss et al., Al Shaw and Elizabeth Weil for ProPublica look at the current fire situation in California and what that might mean for the future and the rest of the country.
In wildfires, as with flooding and heat, climate change doesn’t create novel problems; it exacerbates existing problems and compounds risks. So there is no precise way to measure how much of all this increased wildfire activity is due to climate change. An educated guess is about half, experts say. Its role, however, is growing fast. Within 20 years, climate change promises to be the dominant factor driving larger and more frequent megafires — not only in California, but across the country.
