Climate Change ‘Virtually Certain’ Behind UK’s 35°C Heatwave, Met Office Confirms
Climate Change Intensifies UK Heatwaves, Met Office Warns
The Met Office confirms that climate change is driving extreme heat in the UK, calling it "virtually certain" that human activity caused this week’s 35°C temperatures. Scientists warn such events will grow more frequent and intense, with summers facing the sharpest increases.
Record-Breaking June
England’s June 2025 was its hottest since records began in 1884, averaging 16.9°C. The UK overall saw its second-warmest June, at 15.2°C. East Anglia and southeast England faced extreme heat, with temperatures 3°C above long-term averages. Two distinct heatwaves occurred: one in mid-June and another in late June, the latter hitting southern and eastern England hardest.

While June 2025 surpassed 1976 in temperature, the 1976 heatwave remains notable for its duration, with two-week heat spells nationwide. However, today’s shorter, hotter events highlight evolving climate risks.
Future Projections: Extreme Temperatures Loom
Met Office research warns that 40°C temperatures—once unthinkable in the UK—are now 20 times more likely than in the 1960s. A study in Weather journal estimates a 50% chance of 40°C occurring within 12 years, with 46.6°C now deemed "plausible" under current warming trends.
“The chance of exceeding 40°C has rapidly increased,” said Dr. Gillian Kay of the Met Office. “As our climate warms, this risk will keep rising.”

Health Risks: Heat as a “Silent Killer”
Heatwaves pose severe health threats, particularly to vulnerable groups. Dr. Garyfallos Konstantinoudis of Imperial College London notes: “Heat is a silent killer. Unlike floods, its toll is often hidden, as extreme temperatures exacerbate existing health issues without being listed as a cause of death.”
Why Climate Change Matters
Human-driven greenhouse gas emissions have amplified heatwaves globally. Dr. Amy Doherty of the Met Office explained: “Attribution studies repeatedly show human influence boosts the likelihood and severity of events like the 2018 and 2022 heatwaves.” Projections indicate southeast England will face the most intense future warming.

Preparing for a Hotter Future
With hotter summers inevitable, the UK must adapt infrastructure and public health systems. The Met Office urges policymakers to prioritize heat-resilient housing, green spaces, and early-warning systems to mitigate risks.
In summary, the UK’s escalating heat extremes underscore climate change’s tangible impacts. Reducing emissions remains critical, but adapting to hotter conditions is now unavoidable.
