Annual UK temperatures tops 10C for first time since records began

The UK recorded an annual average temperature of more than 10C for the first time last year, the Met Office said as it confirmed 2022 was the hottest year on record.

And research by Met Office scientists has found that climate change driven by humans made the UK’s record-breaking annual temperature around 160 times more likely to occur.

The full temperature data for 2022 shows that the UK saw a provisional annual average temperature of 10.03C, the highest in records dating back to 1884 and 0.15C higher than the previous record of 9.88C set in 2014.

All four UK nations set new records in 2022, with Wales recording 10.23C, behind the 10.94C recorded in England.

The highest average temperature in Northern Ireland was 9.85C and 8.50C in Scotland.

Wales also recorded a new daily maximum temperature of 37.1C at Hawarden, Flintshire last July.

The previous Welsh record of 35.5 Celsius was also recorded in Hawarden, in August 1990.

The warm conditions would have been expected once in 500 years under a natural climate, without humans warming the planet through activities such as burning fossil fuels, but is now likely every three to four years in the current climate, the experts said.

Climate change

Met Office climate attribution scientist, Dr Nikos Christidis, said: “To assess the impact of human-induced climate change on the record-breaking year of 2022, we used climate models to compare the likelihood of a UK mean temperature of 10C in both the current climate and with historical human climate influences removed.

“The results showed that recording 10C in a natural climate would occur around once every 500 years, whereas in our current climate it could be as frequently as once every three to four years.”

He also said that by the end of the century with medium levels of greenhouse gas emissions, a UK average temperature of 10C could occur almost every year.

The new figures mean 15 of the UK’s top 20 warmest years on record have all occurred this century – with the entire top 10 in the past two decades.

2022’s record-breaking average of 10.03C is followed by 2014 (9.88C), 2006 (9.70C), 2020 (9.62C) and 2011 (9.61C).

The rest of the top 10 is 2007 (9.56C), 2017 (9.53C), 2003 (9.47C), 2018 (9.45C) and 2004 (9.44C).

Last year was also the warmest on record in the 364-year Central England Temperature (CET) series, which began in 1659 and is the world’s longest-running temperature dataset.

The annual mean CET for 2022 was 11.1C, beating the previous record of 11.0C in 2014.

Dr Mark McCarthy, head of the Met Office National Climate Information Centre, said: “Although an arbitrary number, the UK surpassing an annual average temperature of 10C is a notable moment in our climatological history.

“This moment comes as no surprise, since 1884 all the 10 years recording the highest annual temperature have occurred from 2003.

“It is clear from the observational record that human-induced global warming is already impacting the UK’s climate.”

Rich people and capitalism cause climate change and stand in the way of efforts to try and mitigate further rises in temperature. We either destroy capitalism and redistribute the resources that the rich people claim to own or we will see life on Earth wiped out.

Thats our stark choice.

CO2 has a very minimal impact on climate, the earth is naturally warming after suffering the coldest temperatures in the last 10,000 years between 1600- 1750 AD. What caused the ice age which started 100, 000 years ago and lastedfor 75,000 years. What caused the warming that ended that.
