UK summer heatwaves projected to soar 50% higher than global average A new study warns the country could face a ‘future of extreme heatwaves’, carrying with it a raft of serious health risks Image: Shutterstock The UK’s summer temperatures could rise 50% faster than average increases in warming around the rest of the world. That’s the troubling conclusion reached in a new paper published by researchers from the University of Bristol and the University of East Anglia’s Tyndall Centre for Climate Change Research. The scientists used datasets from the Met Office’s UK Climate Projections, specifically the UK Climate Projections 2018 (UKCP18), to investigate how the magnitude and impacts of the UK’s heatwaves are driven by greenhouse gas emissions and how the frequency and severity of such events is likely to rise in the future, even when compared on a relative basis to the rest of the world.
