I have some tentative outdoor evening plans, so I’m checking up on the weather here in Gboro. I couldn’t help but notice the almanac to the right—- record high for May 18 is 95—pretty hot for May—set in 1911, when I venture to think there were not nearly as many cars on the road as there are today. Record low for May 18 is 38—pretty cool for May—set in 1973, when there were a heckuva lot more cars on the road, many of them burning leaded gas.

Interpret for yourselves, dear reader, what this interesting weather fact may or may not say about global warming climate change.
