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.
Climate deniers won’t accept what is happening until it directly affects them, and even then, they still might do mental gymnastics to make it about something else.
