Almost half of people said they had lost at least three hours of sleep each night. The results are consistent with scientific research showing that global heating is damaging sleep across the world. The recent record-breaking heatwave would have been impossible without the fossil fuel burning that is driving the climate crisis, and the poll shows the effects global heating is already having on people. The third heatwave of the summer will arrive this week, the Met Office said on Monday, posing a further threat to lives and livelihoods. Parts of southern England are likely to have highs of about 32C on Tuesday to 34C on Thursday, with 35C predicted for isolated areas on Friday and Saturday, according to the forecaster. graph The vast majority of people in the UK (86%) said their homes were too hot during the June heatwave and a quarter said they or someone in their house had felt physically unwell as a result. About one in five cancelled plans due to the high temperatures, while one in five also had to throw away food that went off or could not be kept cool. The heatwave will have caused hundreds or thousands of early deaths, but the statistical analysis required to determine the number takes time to complete. The UK Health Security Agency has previously found that more than 10,000 people died due to summer heatwaves between 2020 and 2024. In the new poll, conducted by YouGov for Greenpeace, more that half of respondents said their homes needed retrofit upgrades to cope with future heatwaves, but 78% said they would struggle to afford them. Almost half of people said they would support a levy on highly polluting companies to fund these essential upgrades, by far the most popular option. The next most popular was reducing public spending in other areas. Only 5% supported raising personal taxes to fix the UK’s inadequate infrastructure. The government’s official adviser, the Climate Change Committee, has warned for more than a decade that the UK’s plans to protect people from rapidly worsening extreme weather are inadequate. In May, the CCC said the UK was “built for a climate that no longer exists” and needed urgent changes to survive global heating. During the late June heatwave, high monthly temperature records were shattered, with 37.7C recorded at Lingwood, Norfolk , along with record-b
