Much of the UK is facing a record-breaking heatwave, with temperatures perchance reaching 37C successful parts of south-east England.
That would smash the erstwhile June precocious and comes blistery connected the heels of unprecedented vigor successful May too.
But scientists are informing adjacent hotter temperatures are apt successful the years ahead.
They person described the records arsenic "extraordinary" and accidental the UK needs to marque preparations for much utmost vigor a overmuch greater priority.
The temperatures we are experiencing are peculiarly antithetic truthful aboriginal successful the summer, but they are accordant with however our clime is changing.
"We expect expanding temperatures and the breaking of somesthesia records owed to clime change," said Lizzie Kendon, prof of clime subject astatine the University of Bristol and caput of clime projections astatine the UK Met Office.
"What is truthful extraordinary, however, is the borderline by which the grounds volition beryllium broken."
While temperatures alteration people from twelvemonth to year, UK summers person intelligibly been getting warmer.
Between 2015 and 2024, the fig of days exceeding 30C successful the UK much than trebled compared with the 1961-1990 average, the Met Office says.
The maximum somesthesia recorded each twelvemonth has changeable up too.
Reaching 35C was a uncommon lawsuit passim the 20th Century – but six retired of the past 10 years person passed that mark.
Could 40C summers beryllium the caller normal?
The UK's hottest recorded somesthesia present stands astatine 40.3C, acceptable successful July 2022. Before 1990, the UK had not seen 37C.
But these records are astir surely going to support getting broken.
If planetary warming continues astatine its existent pace, temperatures successful the mid-forties could beryllium a superior anticipation for the UK by 2050, according to Met Office projections.
And portion not each twelvemonth volition beryllium hotter than the last, the UK could look adjacent higher temperatures successful the 2nd fractional of this century.
Higher temperatures adust retired the ungraded too. With little moisture available, little vigor vigor is utilized up by evaporation - leaving much vigor to lukewarm the aerial and amplifying the blistery conditions.
Some scientists person besides argued that clime alteration could beryllium making high-pressure systems much apt to get "stuck" - though this is not yet certain.
This tin make a "heat dome" that traps blistery aerial underneath, which is what Europe has been experiencing this week.
"Climate alteration [is] loading the ambiance with other vigor and making utmost temperatures acold much aggravated than they would person been successful the past," said Dr Akshay Deoras, elder probe idiosyncratic astatine the University of Reading.
Scientists accent that the lone mode to bounds rising summertime temperatures is to rapidly chopped planetary emissions of planet-warming gases, specified arsenic c dioxide.
Is the UK acceptable for its hotter future?
Not according to the government's autarkic adviser, the Climate Change Committee (CCC).
In May, it criticised the "woeful" show of successive governments successful getting the UK acceptable for much utmost heat.
"The UK was built for a clime that nary longer exists contiguous and volition beryllium progressively distant successful years to come," the Committee said.
The 40C vigor of July 2022, for example, saw a spike successful deaths and infirmary admissions.
There was besides wide disruption to roadworthy and obstruction networks, portion London Fire Brigade experienced its busiest time since World War Two arsenic blazes raged astir the capital.
"When temperatures emergence this sharply, and for this long, the effects ripple crossed everything we person built - our homes, our offices, our railways, our roads, the precise crushed beneath them," said Xueyu Geng, prof successful geotechnical engineering astatine the University of Warwick.
The somesthesia of alloy railway lines tin emergence to up to 20C supra aerial temperatures successful nonstop sunlight, causing them to grow and buckle. Road surfaces tin besides soften successful the heat, which tin necessitate gritters.

Transport bosses person advised immoderate passengers not to question during the reddish alert heatwave connected Wednesday and Thursday
Only a number of homes person aerial conditioning. Without urgent action, much than 90% of existing homes could overheat during much utmost heatwaves by the mediate of the century, the CCC says.
The CCC has repeatedly urged the authorities to marque preparations for utmost vigor a overmuch greater priority.
It acknowledges that this volition outgo billions of pounds a twelvemonth successful upfront currency but argues that greater concern contiguous would yet prevention wealth successful the agelong run.
It wants to spot cooling technologies specified arsenic aerial conditioning rolled retired successful homes, schools and hospitals, and has recommended mounting maximum somesthesia rules for workplaces to support people's health.
In parts of Europe, moving conditions and schoolhouse days are changed erstwhile reddish vigor alerts are issued - with dense manual labour banned astir midday and children leaving the schoolroom earlier.
UK Floods Minister, Emma Hardy, has antecedently told BBC News that preparing for the changing clime was "something [the government] is truly committed to".
