Latest News About Europe Endures Another Heat Dome as Temperatures Surge

A heat dome traps heat when a strong high-pressure system lingers overhead, acting like a solid lid that holds hot air near the ground. That effect prevents cooler air from moving in while pushing daytime highs even higher, locking in severe temperatures for days. Europe is gearing up for its second run of this in two months, with the U.K. expected to climb past 38°C as further east edges toward 113°F. France just logged its record night ever and now has emergency red alerts in place as the heat dries grasslands and keeps concrete cities from losing warmth even after sunset.
