Climate change is dramatically rising the frequency of utmost excessive temperatures within the UK, new Met Office evaluation has confirmed.

Its annual State of the Climate report says information from 2023 reveals the nation is experiencing considerably extra actually sizzling days.

Its observations recommend there was a rise within the variety of actually moist days too, such because the extended and heavy rain Storm Babet delivered to extensive areas of the nation in October final 12 months.

The report finds the UK can also be seeing a 40% enhance within the variety of what the Met Office describes as “pleasant” days – these with temperatures of 20C or extra – and has change into 9% sunnier over the previous couple of a long time.

Those adjustments could sound constructive, however the UK’s shifting local weather represents a harmful upheaval for our ecosystems in addition to our infrastructure.

For instance, between 1961 and 1990 solely London and Hampshire recorded six or extra days a 12 months with temperatures over 28C – which the Met Office defines as “hot days”. By the most recent decade (2014-2023) just about in all places in England and Wales was seeing this many sizzling days, whereas the South East now will get over 12 in a 12 months.

The enhance within the variety of “very hot days” of 30C or extra has been much more dramatic, trebling over the previous couple of a long time.

Rainfall patterns differ rather more than temperature, however the Met Office says it’s nonetheless attainable to establish a rise within the frequency of the wettest days. It regarded on the prime 5% of wettest days within the interval 1961 to 1990 and located extraordinarily moist days like these had been occurring 20% extra regularly in the newest decade.

“Some of the statistics in this report really do speak for themselves,” mentioned lead creator and Met Office local weather scientist, Mike Kendon. “The climate is not just going to change in the future, it is already changing.”

The new report confirms 2023 was the second warmest 12 months on report for the UK, had the most well liked June ever recorded and the joint warmest September. Separate research by Met Office scientists discovered all these occasions had been made more likely to occur due to human-induced local weather change.

The State of the Climate report finds 2023 was the seventh wettest 12 months on data going again to 1836. March, July, October and December had been all amongst the top-ten wettest for a similar month within the sequence.

It is these climate extremes – of warmth or rainfall – which have the most important influence on individuals, says Prof Liz Bentley, the Chief Executive of the Royal Meteorology Society.

“These changes are leading to more heatwaves and flooding, which profoundly impact communities by straining healthcare systems, damaging infrastructure, and disrupting daily life”, says Prof Bentley.

Other vital climate occasions embrace seven consecutive days with temperatures above 30C in September – a UK first. Unusually the most well liked day of the 12 months was additionally recorded in September (33.5C on 10 September).

Winds of as much as 100 mph (160 km/h) killed 21 individuals throughout Europe when it struck in early November 2023, however the UK was fortunate, the strongest winds bypassed the nation to the south.

The report got here because the report for the world’s hottest day tumbled twice in a single week, in keeping with the European local weather change service.

On Monday the worldwide common floor air temperature reached 17.15C, breaking the report of 17.09C set on Sunday.

It beats the report set in July 2023, and it may break once more.

Climate change has already made excessive climate occasions, akin to heatwaves, heavy rainfall, storms and droughts, extra frequent and stronger in lots of elements of the world. Scientists say these occasions will change into extra intense and occur extra typically until the world could make dramatic reductions in greenhouse gasoline emissions.
