As the UK braces for a bank holiday weekend with temperatures soaring into the high 20s and early 30s Celsius, many are delighted. After a long, wet winter, the sunshine is a welcome boost to morale and vitamin D levels. However, a stark warning looms: the government's Climate Change Committee recently declared that 'the UK was built for a climate that no longer exists.'
The Overheating Crisis
More than 90 per cent of existing homes could overheat within the next 25 years as heatwaves become more extreme. The Committee highlighted the lack of preparedness in schools, offices, hospitals, and transport systems. Julia King, Baroness Brown, stated, 'It's not rocket science – we know what to do. We haven't yet seen a government that's prepared to prioritise adapting to the change of climate and protecting the people and the places that we love.'
Proposed Solutions and Challenges
The Committee suggested following Spain's example, where maximum indoor working temperature is set at 25C, and recommended that children should not sit important exams in the summer. While period homes with thick walls offer some respite, this is not a scalable solution. Friends in new-builds or loft conversions are increasingly investing in air conditioning, following the initial rush on fans during lockdown.
Pets also suffer. Cats often ignore cool mats and retreat to hot attic cupboards reaching 35C. Dogs with thick coats, like my Sybil, struggle despite frozen treats and paddling pools. The only relief comes from staying on cooler ground floors and walking at dawn or dusk.
Urban Heat and Green Spaces
London boasts the second-most green space of any capital city, with 78 parks. Yet when asphalt heats up, it becomes dangerous for dog walking. The slow creep of climate change is evident even in my lifetime. My parents' Home Counties village now hosts a thriving vineyard, a sign of changing conditions.
Growing up, we learned about CFCs and acid rain, both now largely resolved. Today, Net Zero is often dismissed as a woke luxury. But the cost of inaction is far greater. Improvements like the Ulez expansion have made London more pleasant, with clearer skies and visible stars. Electric cars have proven beneficial during global energy crises.
A Call for Action
The desire for Net Zero and embracing change is not just for our pets, who may not live to see the full impact. It is for the next generation. We must prioritise retrofitting homes, implementing cooling measures, and adapting infrastructure. The future of our children and grandchildren depends on it.
