This provides further evidence of how high temperature extremes are becoming increasingly common in the UK as a result of human-induced climate change.
A new record high temperature has been set for June for the second day in a row as the UK swelters in a punishing heatwave.
The Met Office said temperatures had reached 36.4C at Yeovilton, Somerset, on Thursday afternoon, provisionally making it the UK’s hottest June day on record.
The current heatwave is driven by a “heat-dome” – an area of high pressure that stalls over a region and traps heat – settling over western Europe and bringing extreme conditions across the continent.
Vulnerable
Human-driven climate change, mostly caused by burning fossil fuels, is making such extreme heatwaves more frequent and intense.
Professor Ian Bateman, OBE, Co-Director of the LEEP Institute at the University of Exeter Business School and environmental economist, said: “Carbon dioxide is the atmospheric gas that keeps earth warm at night – but add too much and earth overheats. In 1909 it hit its highest level since the dawn of modern man, and every year since then it gets higher and the earth gets warmer.
"It’s not the temperature alone that threatens us but over the last century the world has been warming at what is very likely to be its fastest speed in the whole history of the earth. This affects everything, not just making us feel hot but disrupting water and ocean cycles, food production and all living things.
"Doing nothing will at very best leave us all impoverished – more likely far worse than that. The irony is that the alternatives, leaving oil and its massive tax breaks behind and investing in renewable energy would lower household bills, make us secure against oil wars, and of course give us a better future.
"Those politicians that argue against this presumably get some personal benefit from persuading people to make themselves poorer, more vulnerable to overseas oil, and give up their future wellbeing.”
Swathe
The new high surpasses both the previous record set on Wednesday, when temperatures reached 36.1C in Gosport, Hampshire, and the long-standing record for June heat which dates back to the infamous summer of 1976.
London Ambulance Service said it had recorded the highest ever number of life-threatening emergencies in its history “driven by the extreme heat” on Wednesday, while doctors have warned of “awful conditions” in NHS facilities in the heatwave.
Schools and nurseries have closed, a hosepipe ban has been brought in for Kent amid surging demand, transport services have been disrupted and one rail operator has urged people not to travel for beach trips because of the extreme heat.
A swathe of England and Wales remains under a rare red warning for extreme heat, for a second day in a row in the face of hot and humid conditions.
Warnings
The Met Office said the new record for the hottest June day could be exceeded again in the coming hours.
Greg Wolverson, deputy chief meteorologist said: “We’ve seen a new provisional June maximum temperature record for a second consecutive day as the heatwave continues.
This provides further evidence of how high temperature extremes are becoming increasingly common in the UK as a result of human-induced climate change.
“This marks unprecedented heat for the month of June and provides further evidence of how high temperature extremes are becoming increasingly common in the UK as a result of human-induced climate change.
“There’s a chance of this record being challenged again as the warmth moves more markedly east on Friday, before a gradual easing in temperatures through the weekend.”
Earlier the Met Office extended its red warning until 9pm on Friday for London and parts of east and South East England, stretching across Oxfordshire and Bedfordshire, Hampshire and Kent – the first time it has issued red heat warnings over three consecutive days.
Life-threatening
Amber heat warnings are in place for a wider area on Friday, and are running into Saturday for parts of east and South East England.
Meanwhile, a yellow warning is in place for thunderstorms for South West England on Thursday night, and for northern Scotland on Thursday afternoon and evening, while swathes of Scotland, England, Wales and Northern Ireland face yellow warnings for thunderstorms on Friday.
Red heat health alerts have also been issued by the UK Health Security Agency for the East of England, East Midlands, London, the South East, the South West and the West Midlands, and amber heat health alerts for the North East, North West, and Yorkshire and the Humber.
London Ambulance Service responded to 642 category one calls on Wednesday – the highest number of life-threatening emergencies in its history – in what was the emergency service’s fifth busiest day ever.
Category one calls include the most serious, life-threatening injuries and illnesses such as cardiac arrests and patients who are not breathing.
Extreme
Chief executive Jason Killens said: “We have seen the highest number of life-threatening emergencies in our history, driven by the extreme heat across London.
“Our crews are working very hard in challenging conditions to care for patients and I would like to take this opportunity to thank all our people for their incredible hard work.
“Please help them to help you by taking care of yourself and others – stay out of the sun and keep hydrated.”
In Wales, a 50-year-old man from Cilfrew, Neath Port Talbot, died after entering the water at Aberavon beach on Wednesday, police said.
The latest heatwave has prompted renewed calls for the UK to be better prepared for the rising risk of extreme heat that a changing climate is bringing, including cooling for hospitals, schools and care homes, heat regulations for workplaces, and to prepare infrastructure against rising temperatures.
Measures
The Royal College of Physicians (RCP) said doctors have described severe, unsustainable pressure on the workforce, with very few settings having air conditioning, staff “really struggling” and resident doctors battling the heat while sleep deprived.
One physician has warned “conditions are awful” because of overcrowding, another said two machines used to treat cancer had stopped amid the heatwave, and there had been reports of patients on geriatric wards – one of the group’s most vulnerable to heat – facing temperatures of up to 35C.
And as many schools closed or brought in early pick up times in the face of sweltering conditions, Sir Keir Starmer has said it is up to schools to decide for themselves the best course of action.
Asked if it was right that children’s education suffers because of the extreme weather, the Prime Minister said: “It is very hot, and obviously schools will have to take the appropriate measures, and each school will gauge for themselves the measures that are appropriate.
Adapts
“But it is important that we as a Government co-ordinate this across the country, and actually with all of the countries within the United Kingdom, which is what we’re doing,” he said, adding Cobra meetings were taking place “at the official level”.
The National Education Union has written to Education Secretary Bridget Phillipson, urging her to set out a timetable for equipping schools with air conditioning.
During a visit to Beanfield Primary School in Corby, Northamptonshire, Ms Phillipson said the school closures showed there was “more to do” to ensure buildings are equipped to deal with extreme heat.
And London mayor Sir Sadiq Khan has said air conditioning should be rolled out to schools, offices and hospitals in the capital as it adapts to more intense and frequent heatwaves, as he launched the city’s first ever heat plan to keep Londoners safe.
