As the UK’s third summer heatwave drew to a close, Ed Miliband used his first annual climate statement to Parliament to warn of the growing impacts of climate breakdown in the UK, backed by the Met Office’s latest State of the UK Climate report.
The report shows how extreme weather is now the norm in the UK, with data from hundreds of weather stations revealing that the hottest days are becoming more frequent and severe, and intense rainfall has increased.
The same day the State of the UK Climate report was released, Climate Barometer’s Niall McLoughlin published an opinion piece in Climate Home News, highlighting the urgent need for better communication around extreme heat.
Niall explains that despite improvements to heat warnings, a disjointed landscape of heat communications means that many people feel the UK is poorly prepared for heat risks. Drawing on a range of opinion insights, he calls for improvements such as using social research to tailor communication, focusing more on longer-term heat preparedness, and closing perception gaps which may lead people to underestimate risks.
He points also to locally-led tree planting projects as an example of the kind of long-term, community-based preparation needed. Separate research from Cardiff University shows that such efforts must accelerate significantly to help cities adapt to intensifying heatwaves. Their new findings reveal that urban tree planting can cut city temperatures by up to 5°C, making it one of the most effective tools for cooling overheated streets.
New survey data shows that nearly three quarters (71%) believe the government should make adapting to climate risks like floods, heat, and droughts an “urgent, top priority”, while only a minority (15%) disagreed.
The findings, from a nationally representative UK survey in collaboration with Flooded People, highlight the public desire for action on impacts like floods, storms, heat and drought.
While experts in the climate sector separate out ‘adaptation’ and ‘mitigation’, our new data shows that a majority (55%) think these two broad responses should be prioritised equally (echoing our previous tracker insights).
The survey also showed that most people report one or more direct experience of climate impacts. Heatwaves and extreme heat are the most commonly experienced climate impact (felt by 46%). A third have experienced ‘severe storms’ (30%), and a fifth say they have been directly affected either by flooding or poor air quality (both 21%). It’s less than a third (29%) who still say they have “no experience of impacts” at all.
Following months of sweltering heatwaves, record-breaking wildfires and five regions in drought, this week it was provisionally confirmed that 2025 was the UK’s hottest summer on record.
While this new record was made ‘70 times’ more likely by climate change, the overwhelming sentiment is that the country is not prepared for more summers like this. The UK’s official climate advisors, practitioners who work on the frontline of the heatwave response, and the British public all agree that the UK isn’t ready for more extreme weather,worsening heat, and compounding risks like water scarcity and wildfires.
At the same time, there are important perception gaps to address. Despite the alarming statistics about heat-related deaths in the UK, many people were looking forward to the first heatwaves this summer. Lots think that heatwaves will only become a problem for the UK in the future. And many believe that hot weather poses more of a risk to other people, not themselves.
In this context there are important conversations now happening about how to grapple with the growing climate risks in the UK, including the sudden lurch towards air conditioning (despite its potential to make heat risks worse).
