UK Must Adapt as Climate Creates Hotter, More Unequal Nation

Britons will need to adapt to living in a hotter country, even if it does not always feel that way, as climate change intensifies.

Temperatures are already 1.4C above the historic norm and are projected to rise by 2C in the next two decades, according to a major report published Wednesday by the Climate Change Committee (CCC). While the increase may appear modest, it will result in significantly higher summer temperatures, including heatwaves reaching 45C and lasting over a week—surpassing the 2022 record of 40C—along with more frequent droughts and severe flooding.

Every region of the UK and nearly every aspect of infrastructure—from transport and communications to housing, schools, hospitals, and care homes—will be affected. “The UK was built for a climate that no longer exists today and will be increasingly distant in years to come,” the CCC report said.

Without strong preventive measures, a hotter Britain will also become a far more unequal country, with extreme weather disproportionately affecting lower-income populations compared to those with resources to adapt.

Inequalities begin before birth. A study published this week by Wellcome found that pregnant women are especially vulnerable to high temperatures. Without means to cool their homes, women face higher risks of pre-term birth, stillbirth, congenital anomalies, and obstetric complications.

Schools also present a challenge. The CCC cited research showing students were more likely to fail exams taken at outdoor temperatures of 32C compared with 22C. Although the CCC recommends all schools install air conditioning by 2050, overstretched education budgets could result in uneven implementation or none at all.

Temperatures at home matter as well. “Tropical nights,” when temperatures do not drop below 20C, are expected to become more common, disrupting sleep. With 90% of British homes at risk of overheating, the CCC said air conditioning may be the only solution, but families unable to afford it may be able to cool only one room.

Food prices have already surged due to climate impacts on crops and yields, adding roughly £360 to the average annual food bill, according to the Energy and Climate Intelligence Unit. Prices are forecast to rise 50% by November compared with 2021. Wealthier households may weather such shocks, but the poorest will struggle.

When homes flood, higher-income residents may find it easier to relocate or install flood prevention measures, while the poorest are more likely to remain stuck. Lower-income individuals also have less access to nature, which can provide relief during heatwaves.

“Climate change consequences aren’t felt equally,” said Cath Smith, head of social impact at the Green Alliance thinktank. “Impacts such as heat and flooding intersect with inequalities in income, health, housing and place, leaving some communities facing greater harm with fewer resources to adapt or recover. If policy doesn’t acknowledge the growing and unequal impacts of climate change, then there is a real risk that rising temperatures will exacerbate inequalities.”

There will also be political consequences, warned Sam Alvis, associate director at the IPPR thinktank. Ironically, given that senior figures in the Reform party, led by Nigel Farage, have cast doubt on climate science and vowed to scrap climate policies, the far right could benefit.

“As we’ve seen in Valencia, Los Angeles and elsewhere, when increasingly severe and frequent climate impacts strike, populists are quick to exploit public anger over a lack of preparation, using it to advance their own agenda and weaken support for climate action more broadly,” Alvis said.

“Government’s priority, especially when resources are tight, should be to help those least able to protect themselves, and to spend on things that actually lower the risk of climate impacts – infrastructure or improvements to homes and buildings – rather than masking that risk, like subsidised insurance.”

Others share the desire for urgent adaptation but argue prevention should be the top priority.

Dr. Friederike Otto, professor of climate science at Imperial College London, said: “The UK is already experiencing the stark reality of climate change through harsher droughts, intense summer heatwaves, and significantly wetter winters.

“While adaptation is a vital piece of the puzzle, we can’t simply adapt ourselves out of this problem. The ultimate and most effective way to tackle climate change remains the rapid transition away from fossil fuels until our societies reach net zero.”
