How can we stop record heat deaths if we can’t accurately record temperatures?
Spain was one of many European countries hit by record-breaking heat this summer. For three straight weeks in August, temperatures across the Iberian Peninsula soared past 40°C, with no relief after dark. Nights stayed above 26°C, a clear sign of the Urban Heat Island effect, where asphalt and concrete trap the day’s heat and release it slowly at night, preventing temperatures from naturally cooling off.
