## In brief

- A new study compares the 2021 heat dome in British Columbia with a previously overlooked heat wave during World War II.
- The study suggests the 2021 heat dome's impacts could have been much worse for British Columbians, despite its widespread devastation.
- The authors describe the 2021 event as a 'near miss' and argue the earlier heat wave offers valuable lessons.

## Why it matters

The comparison with a historical heat wave offers lessons for assessing extreme heat risk and preparedness, which matter for science readers working on climate impacts and adaptation.
