Europe's latest spell of sizzling heat, which ended last week, caused a threefold rise in heat-related deaths because human-induced climate change boosted the intensity of the heat wave, British scientists said.

Around 2,300 people died of heat-related causes across 12 European cities during the severe heatwave that ended last week, according to an analysis.

Researchers said they believe that human-driven climate change probably intensified the recent European heat wave and increased the number of heat-related deaths.
