We had a lovely double rainbow yesterday:

But this morning, we had something else entirely:

Canadian wildfire smoke raised the air-quality index in Chicago to well over 150 this morning. This is the satellite view from about 20 minutes ago:

Unlike the last couple of weeks, however, the smoke has now descended to ground level, making Chicago look like it did in the 1970s, before the Clean Air Act started to do its thing:

We're hoping the smoke clears up soon. And that the Canadian firefighters will get the prairie fires under control.
As for the politics, well, the droughts and changing moisture patterns leading to the fires up north are predicted consequences of human-induced climate change.
