Before humans began using fossil fuels, heatwaves like those we see today were rare. They happened once every 50 years. Now, due to climate change, we can expect them every five years. This alarming shift was highlighted in a swift study by World Weather Attribution (WWA). They focused on the first heatwave in the UK that started on June 16, 2025.
Most of the extreme heat was felt in Southeast England, but it affected parts of the Midlands too. Dr. Ben Clarke, a researcher at Imperial College London, emphasized that as temperatures rise, the UK will face more dangerous heatwaves. This leads to more heat-related deaths, additional stress on the NHS, transport issues, and worsening air quality.
In regions like Derbyshire, local councils, particularly those led by Reform UK, are resisting efforts towards net-zero emissions. Carbon Brief has suggested that these councils might hinder investments in renewable energy. Even as climate crises deepen, the fossil fuel lobby seems determined to push against necessary changes.
In 2022, heatwaves caused over 60,000 deaths across Europe. The WWA identified that the rising temperatures from climate change pose serious risks to health, especially for vulnerable groups such as the elderly and those with health conditions. Dr. Otto from Imperial College noted that those weak in society often feel the harshest impacts, as they lack access to cooling systems or adequate living conditions.
This summer’s heat is also straining hospitals still recovering from the Covid-19 pandemic. The current system is not equipped to handle the enhanced demands that extreme heat will bring. Yet, crucially, the UK government isn’t adequately tracking the effects of heat on healthcare.
The dry weather has already damaged peatlands in Derbyshire, and farmers are worried about crop yields. Recent findings indicate a drop in soil moisture, which is essential for healthy crops. According to the Copernicus satellite data service, while soil moisture decreases, the air is holding more moisture, worsening the greenhouse effect and potentially leading to severe weather challenges later in the year.
Building resilience against climate change is more important than ever. We need to rethink our strategies regarding housing, food supply, and healthcare. Unlike other countries that focus on cooling systems, many UK homes still fight the heat as if it were the cold. WWA points out that while regulations for new homes address heat, much of the existing housing remains at risk of overheating.
Disparities also come into play, where poorer urban neighborhoods often have higher temperatures due to dense housing and fewer trees. We should also consider monitoring wet-bulb temperatures before strenuous activities, much like they do elsewhere. Innovative ideas like satellite-driven early warning systems are being tested worldwide to help workers avoid dangerous heat and humidity.
As future heatwaves become more frequent, we need to ask our local representatives what measures they are taking to protect our communities and enhance resilience against these rising temperatures. The time to act is now.
