Heat-related deaths in England and Wales could rise up to 50-fold in the next 50 years as an ageing population is hit by dangerous climate change, a study warns.The warning comes as parts of the UK face a third heatwave in a month pushing temperatures above 30C,

A new study suggests that, under realistic scenarios of high emissions and socioeconomic development, annual heat-related deaths in the U.K. could rise to about 50 times current rates by the 2070s, but that climate change mitigation and adaptation could significantly limit this rise.

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.
