UK heatwave: The areas most at risk from dangerous temperatures

Millions more people at risk from dangerous summer temperatures if the climate crisis continues

The parts of the UK most at risk from the health risks of extreme heat have been identified by researchers from the University of Manchester for Friends of the Earth.

Communities most vulnerable to the dangerous health impacts of soaring temperatures are those with a high number of older people and children, those without green space to shelter from the heat, and those where the type of housing, such as high-rise buildings and mobile homes, is most susceptible to overheating.

Researchers found the top five local authorities with the most ‘at risk’ neighbourhoods are Birmingham, Newham, Tower Hamlets, Hackney and Nottingham. A full list of all the areas most affected is available here.

The research looks at which neighbourhoods (areas with an average population of 1,700) across England are most at risk of heat now and in future warming scenarios.

In all scenarios, the communities set to be most affected by global heating are those with below-average carbon footprints – those less responsible for the climate crisis. The research also finds that people of colour are four times more likely to live in areas at high risk of dangerous levels of heat.

The experts say health-threatening heatwaves will become more intense due to climate change, putting millions more people at risk from dangerous summer temperatures.

According to the Met Office, hot weather can place strain on the heart and lungs, meaning that the majority of serious illness and deaths caused by heat are respiratory and cardiovascular. Older people, those with pre-existing health conditions and young children are especially at risk.

Even if the world stays on track to meet the global goal to limit warming to 1.5C, more than 3,000 of the most vulnerable neighbourhoods – more than six million people – will regularly be exposed to ‘very hot weather’ of 27.5C for five or more days during the summer months. If temperatures rise to 3C, then the same areas will be regularly exposed to dangerously hot temperatures of over 30C.

Friends of the Earth is calling for the 3,000 most vulnerable neighbourhoods to be prioritised for publicly-funded adaptation projects and greater efforts to reduce planet-heating greenhouse gases.

Mike Childs, head of research at Friends of the Earth, said: “Extreme heatwaves and health alerts like we’re seeing this week, will become much more frequent and severe due to climate change. To prevent the most dangerous scenarios becoming a reality, all countries, including the UK, must make greater efforts to prevent runaway climate breakdown.

“Suggestions by some politicians that the UK should dial back on climate goals are short-sighted and reckless. People on the frontlines of the climate crisis in the UK and overseas are already being hit by its impacts, despite being the least responsible.

“We need governments to double-down on cutting emissions and providing funding for climate adaptation programmes, such as planting street trees.”

Global temperatures are already 1.1C above pre-industrial levels. Under the Paris Agreement, governments have agreed to limit warming to 1.5C to avoid catastrophic climate change.
