The Met Office has issued a stark warning that UK temperatures could reach 45°C by 2056, as heatwaves become more intense due to human-induced climate change. The warning comes as sweltering temperatures sweep across the UK, with red extreme heat warnings already in place.
Current Heatwave and Red Warnings
Meteorologists have issued rare red weather warnings for extreme heat, reflecting the potential for significant impacts on health, infrastructure, and daily life. Temperatures over the coming days are anticipated to smash UK June records.
Future Heatwave Scenario
Scientists at the Met Office have highlighted how similar events could become 'significantly more intense in the future, with a plausible scenario showing UK temperatures reaching 45°C by 2056'. The prediction comes 50 years after the start of the 1976 summer heatwave, one of the most significant weather events in UK history.
To mark the anniversary, the Met Office has developed a plausible '2056 scenario', based on around 2.5°C of global warming, to show how a prolonged heat event similar to 1976 could evolve. The scenario indicates that temperatures could peak at 45°C in England, 41°C in Wales, 38°C in Scotland, and 30°C in Northern Ireland. It also shows a prolonged heatwave lasting around two weeks, including nine consecutive days where temperatures exceed 40°C somewhere in the UK.
Expert Comments
Professor Stephen Belcher CBE, Met Office chief scientist, said: 'The heatwave this week will be a significant weather event, with a red extreme heat warning issued. Human induced climate change has made events like this more likely and more intense. To see temperatures like this in the UK in June is sobering. Events like this bring home the implications of climate change, with very high temperatures and humidity bringing significant health implications from heat stress, as well as impacts to a range of sectors such as transport, energy and water supply.'
Professor Ed Hawkins MBE, professor of climate science at the University of Reading, said: '1976 was an extraordinary event, but it happened in a much cooler climate. As global temperatures rise, heatwaves like this are becoming more intense and more frequent.'
Climate Change Context
The Met Office noted that since 1976, the UK's climate has fundamentally changed, with average UK summers having warmed by around 1.4°C. Research indicates that a heatwave comparable to 1976 would already be about 3°C hotter in today's climate.
Professor Hayley Fowler FRS, of Newcastle University, said: 'The 1976 heatwave was about more than just heat, it led to drought, water shortages and significant impacts on daily life. In a warmer climate, those impacts are likely to become more severe.'
Impacts and Risks
The 1976 heatwave brought record-breaking temperatures, drought, water restrictions, and pressure on infrastructure. Images of standpipes in streets became symbolic of the impacts felt across the UK. The Met Office warned that these risks are already being reflected in current conditions, with the red warning highlighting potential severe impacts across sectors, particularly for vulnerable people and critical services.
Scientists believe future heatwaves could bring even greater challenges, including increased health risks, pressure on water supplies, wildfire risk, and impacts on food production.
