The Air Quality Index in my town is currently 260 (very unhealthy) due to a surge in wildfires in western Canada and the northwest US. There are additional smaller fires not shown on this map at this zoom level.
From the interactive map it looks like the worst air in the world right now.
Nothing compared to September 2020. AQI was off the charts bad.
And it looked like this outside during the daytime: https://media.npr.org/assets/img/2020/09/11/20200909_jdl_fires_001_custom-49bb317ab3c1b07b980f63f3d2c980eaf45cf9c2-s1000-c85.webp
