A lot of us drive, bus, and bike east-west. The car traffic since school started has cost an extra 20mins one way in to get to my office. 540

Reposted by Christina KumlerTomer Burg @burgwx.bsky.social · 15/07/2026With how thick the smoke plume is today, it also had an impact on temperatures by reducing sunlight at the surface.
