In a fast attribution examine – which appears at how a lot of a task local weather change performs – the Met Workplace say the typical temperature was made round 130 instances extra probably on account of human-induced local weather change.
And step again from this summer time and there’s clue to our altering local weather within the temperature document itself.
In a local weather that is not altering, new data ought to develop into progressively rarer, as a result of each time a document falls, it raises the bar for the following one.
Take into consideration the 100m race. Every time somebody units a brand new document, it turns into more durable to beat. And there is one other factor. Usually data are solely ever damaged by just a few fractions of a second – typically only a millisecond or two.
In June 1991, for instance, Leroy Burrell ran 9.90 seconds, beating Carl Lewis’s 1988 world document of 9.92 seconds by simply two hundredths of a second.
Now have a look at the UK summer time temperature document. Till final 12 months, the 4 hottest summers on document had been separated by simply 5 hundredths of a level.
Then 2025 beat the earlier document by 0.34C. And this summer time has crushed that new document by one other 0.40C.
So after years when the document moved by tiny fractions, in simply two summers the bar has been raised by 0.74C.
Head of Local weather Attribution on the Met Workplace, Dr Mark McCarthy stated that summer time 2026 was “exceptional” and we will count on to see extremes occurring extra steadily sooner or later due to local weather change.
So why is that this occurring so shortly right here? The UK sits on the western fringe of Europe, the fastest-warming continent on Earth – warming at roughly twice the worldwide charge.
There are just a few causes for that. Land heats up sooner than the oceans, elements of Europe stretch into the quickly warming Arctic, and adjustments in climate patterns have favoured extra frequent and intense summer time heatwaves.
Scientists are nonetheless figuring out precisely how a lot every issue contributes, however the result’s clear: the background local weather through which British climate occurs is getting hotter.
None of this implies the UK will break its summer time document yearly. Climate will all the time give us cooler summers in addition to hotter ones. However the sample is turning into unmistakable: data that after marked the acute fringe of the UK’s local weather are being overtaken with exceptional pace.
So the query shouldn’t be whether or not the UK will expertise summers hotter than this one. It’s how typically they are going to come – and the way a lot hotter they could be.
