As summers become longer, warmer and drier in the US west, forests are being transformed into perfect staging grounds for repeated wildfires of increasing ferocity.

Researchers at the University of Washington looked through data on the very worst bad air days, totaling roughly a week each year, across the country since 1988. While the rest of the country has experienced a sharp improvement in air quality, a sprawling patch that includes parts of Idaho, Wyoming and Montana, much of Utah and Nevada, and parts of California, Oregon and Washington has got significantly worse.
