UK in 50 years with extra heatwave deaths, hovering meals prices and remodeled properties

Over the weekend, the UK experienced its hottest May bank holiday on record, but experts warn that such extreme weather conditions are projected to become commonplace in the coming years

Over the weekend, Britons flocked outdoors to soak up the glorious sunshine on what was logged as the hottest May bank holiday on record. However while many embraced the scorching heatwave, specialists are gravely worried that such extreme weather will shortly become commonplace.

While we’ve previously coped with sweltering summer days using an electric fan and a reliable ice lolly, this simply won’t cut it in the coming years. Climate change is set to alter everything from what our supermarket aisles contain to how lessons are delivered in school halls.

If we were to hop in a time machine to a baking British summer roughly 50 years from now, would we even recognise our houses, workplaces, and neighbourhood hospital?

Overstretched NHS

According to the UK Health Security Agency (UKHSA), an estimated 10,781 heat-related deaths in England were documented as “a direct consequence of heatwaves” between 2020 and 2024. Without immediate adaptation, it’s forecast that this number will rocket to approximately 11,000 fatal cases every single year by the 2050s.

It is a demographic shift that will burden the taxpayer heavily. While heat-related deaths in England presently cost the economy around £6.8 billion each year, this is forecast to rocket to £14.7 billion by mid-century. Andrew Hulbert, a sustainability expert with a master’s degree from University College London (UCL), cautions that Britain’s rapidly ageing population will leave the NHS extremely exposed.

There are now almost 1.4 million people in the UK aged 85 and older, a figure estimated to more than double over the next two decades, reports the Mirror. Andrew said: “The hotter it gets, the more pressure it puts on the NHS, certainly over the next 50 years.

“But I’m talking the next five to 10 years.”

Spiralling supermarket prices

As the WWF report emphasised, climate change presents an unprecedented danger to food security. Drought and torrential rainfall are already devastating global wheat harvests, which are essential for bread, while extreme weather is making it increasingly challenging to locate areas suitable for cultivating coffee beans.

A time traveller stepping into their local supermarket 50 years from now would probably have to navigate a dramatically altered shopping experience. Although the UK may eventually be capable of growing some exotic fruits domestically, shifting global climates will impact the supply of conventional fruit and vegetables, causing certain varieties to vanish.

Refrigeration will also pose a major challenge, with the commercial freezers presently deployed in UK supermarkets lacking the capability to keep food chilled in temperatures surpassing 40°C. Supermarkets will be compelled to invest in industrial-strength cooling systems, typically found in Middle Eastern nations, with the expense being transferred to shoppers through higher prices.

“Skins” for properties

The typical British dwelling isn’t generally constructed to endure severe heat, yet it’s becoming an increasingly pressing concern. Studies from the Grantham Research Institute disclosed that over half of British properties face overheating risks, a figure expected to rocket to 90% under a 2°C warming scenario.

It’s improbable that we’ll witness conventional British houses demolished in favour of more futuristic dwellings, as there’s simply “not enough money on earth that can make that happen,” observes Andrew. He continued: “What we’re seeing in places like Greece and Athens in particular, they’re starting to build what they call ‘skins’ around the outside of a building.

“So imagine a dome around the outside of the building, a metre away from the edge Rebuilding a house is going to cost a quarter of a million pounds, but to stick a skin around the outside is going to be tens of thousands.”

Sweltering schools

Combined research from the Met Office and University College London determined that measures must be implemented in schools now to adapt the environment. Without financial support, it’s forecasted that pupils could be prevented from studying in traditional classrooms for up to eight days annually due to severe heat events.

However, such interventions won’t come without a hefty price tag. This encompasses the installation of air conditioning and heat pump systems, which pose a significant financial challenge for financially stretched UK schools.

Andrew commented: “The one challenge we know with schools is they’re not flush with money. They have to be very careful about how they spend their money, and things like heat pumps and air conditioning systems are expensive assets for them to add, but also to maintain and replace as time goes on as well.”

Workers’ safety

The Climate Change Committee (CCC) has declared that the UK was “built for a climate that no longer exists”, urging the government to implement maximum temperature laws to safeguard workers’ health. The CCC doesn’t specify a maximum temperature but does reference Spain, where the highest legal indoor working temperature is 27 °C for sedentary work and 25 °C for light physical work.

A report by the Autonomy Institute concluded that two-thirds of the British workforce could potentially be working in heatwaves surpassing 35 °C by the end of the decade. Reflecting on this, Andrew noted that changes will need to be implemented to ensure worker safety. He said: “I wonder in the future if we start having days off.

“It’s too hot to come in today, not safe to travel, so you stay at home.”

Tourism shifts

While there are precious few bright spots to climate change, Andrew does observe that there could be some benefits for UK tourism, as travellers ditch sunny Spain for English seaside resorts. Andrew elaborated: “It was like when we saw the Northern Lights in the UK last year, tourism in Iceland was really impacted because you don’t need to go to Iceland anymore to see them.

“So I think ‘staycations’ are probably more likely, and I think maybe travel will be impacted by that. Also, we know that the price of fuel is obviously impacted at the moment by everything that’s going on.

“So people are maybe making that choice as well.”

Water shortages

Yet a tourism surge will collide with a dire national water emergency. The Environment Agency warned that by 2055, England confronts a massive 5 billion litre daily deficit for public water supplies unless “urgent action” is implemented.
