Research predicts a significant increase in heat-related fatalities in England and Wales as climate change escalates. Current trends suggest that annual heat-related deaths could rise to 10,317 by the 2050s, and exceed 34,000 by the 2070s under a worst-case warming scenario of 4.3C. Even limiting warming to 1.6C while implementing high adaptation efforts could still result in a sixfold rise in annual deaths. The 2022 heat wave demonstrated a significant precedent, highlighting the urgency and severity of the climate crisis and the need for effective mitigation strategies.
A new study calculates that heat mortality could rise more than fiftyfold in 50 years due to climate heating, projecting over 30,000 heat-related deaths annually by the 2070s.
In the worst-case scenario of 4.3C warming by the end of the century, heat-related deaths could exceed 34,000 by the 2070s, even with minimal adaptation.
