"Climate Change Made UK’s 32°C Heatwave 100 Times More Likely, Scientists Find"
UK Faces 2025 Heatwave Fueled by Climate Change, Scientists Warn
As the UK prepares for its first major heatwave of 2025, scientists attribute the soaring temperatures to human-driven climate change. Research by World Weather Attribution reveals that this weekend’s forecasted highs of 32°C (90°F) are now 100 times more likely due to global warming. Historically, such intense June heat occurred once every 2,500 years—today, it’s expected every 25 years.
Rising Temperatures, Growing Risks
Global temperatures have risen by 1.3°C (2.3°F) since pre-industrial times, making heatwaves hotter and more frequent. Previously, a three-day June heatwave above 28°C (82°F) struck the UK once every 50 years. Now, there’s a 20% chance annually—a tenfold increase.
Weekend Forecast and Health Warnings
The Met Office predicts highs of 33°C (91°F) in Humberside and sustained 30°C+ temperatures in London through Monday. The UK Health Security Agency (UKHSA) issued an amber alert, warning of potential fatalities. “Climate change has turned warm summers into deadly heat,” says Dr. Friederike Otto of Imperial College London. Extreme heat in June—before people acclimate—poses severe risks, especially for the elderly.
2022’s Deadly Precedent
The 2022 heatwave saw 40.3°C (104.5°F) in Lincolnshire, triggering over 3,000 excess deaths. Professor Mike Tipton warns, “32°C days in June now endanger lives,” emphasizing that heatwaves are the planet’s deadliest weather event.
Future Projections and Wildfire Threats
The Met Office warns summers akin to 1976’s record heat could become routine. By 2035, there’s a 50% chance of 40°C temperatures, with 46°C “plausible.” Rising heat also fuels wildfires—2025 has already broken UK wildfire records.
Emergency services urge caution amid “very high” fire risks this weekend. Experts advise avoiding barbecues and discarding cigarettes safely. With heatwaves intensifying, the message is clear: climate action is urgent to curb escalating threats.
