Wildfires and climate change are locked in a vicious circle: Fires worsen climate change, and climate change worsens fires. Scientists, including those at the World Resources Institute, have been increasingly sounding the alarm about this feedback loop, warning that fires don’t burn in isolation — they produce greenhouse gases that, in turn, create warmer and drier conditions that ignite more frequent and intense fires.  Last week, wildfire smoke prompted another round of unhealthy air quality in California. Fires in Oregon and Northern California sent smoke into Sacramento and the San Francisco Bay Area. And it’s a global nightmare: This summer, world temperatures hit an all-time high, the worst U.S. wildfire in more than a century devastated Maui, a deadly fire in Greece was declared Europe’s largest ever, and swaths of the Midwest and Northeast have been blanketed by smoke from Canada’s forest fires.
