The UK teeters on the brink of its hottest June ever as rare red warnings stretch across England and Wales. Temperatures are forecast to hit 38C to 40C in some areas, eclipsing the previous record set in the sweltering summer of '76. This is not just a heatwave - it's a stark warning of what's to come if we don't act on climate change.
UN Secretary-General António Guterres delivered an urgent message during London Climate Action Week, likening the city to a scene from Charles Dickens' 'A Tale of Two Cities'. He described "a tale of two crises": a climate crisis driving higher temperatures and an energy crisis exposing our reliance on fossil fuels. Both, he stressed, have their roots in the same problem – our addiction to fossil fuels.
Across the Channel, France has already seen its hottest night since records began, with 19 heat-related deaths prompting Prime Minister Élisabeth Borne to convene an emergency meeting. The European Green Party has lambasted governments for failing to address climate change adequately, criticising attempts to roll back environmental protections like the Nature Restoration Law.
Back home, councils and government departments are scrambling to mitigate the impact of the heat. Bristol City Council has activated its severe weather emergency protocol (SWEP) to help rough sleepers, providing cool spaces, water, sunscreen, and advice. The Department for Education has issued guidance to schools and educational settings, recommending loose, light-coloured clothing and increased hydration to protect children.
The Met Office warns that such heat events could become more frequent and intense. Scientists have developed a "plausible 2056 scenario" based on 2.5C of global heating, projecting potential temperatures of 45C in England, 41C in Wales, 38C in Scotland, and 30C in Northern Ireland. This includes prolonged heatwaves with multiple consecutive days exceeding 40C.
Practical advice for the public remains essential: stay hydrated, avoid strenuous activity during peak hours (11 am to 3 pm), and keep homes cool. Know the signs of heat exhaustion (tiredness, dizziness, headache, nausea, excessive sweating) and heatstroke (confusion, seizures, loss of consciousness, high body temperature, hot red skin). Seek emergency medical attention if you suspect heatstroke.
