I was thinking about lightning today, as we've had a lot of storms recently. I came across the following map from NASA showing the frequency of lightning strikes worldwide. Sharing this because it's a well done map and the page itself is worth a good five-minute read.

Good luck to all those starting school, either as students or teachers.
