LONDON — Britain shattered its record for highest temperature ever registered Tuesday amid a heat wave that has seized swaths of Europe — and the national weather forecaster predicted it would get hotter still in a country ill prepared for such extremes.
The typically temperate nation was just the latest to be walloped by unusually hot, dry weather that has gripped the continent since last week, triggering wildfires from Portugal to the Balkans and leading to hundreds of heat-related deaths. Images of flames racing toward a French beach and Britons sweltering — even at the seaside — have driven home concerns about climate change.
