UK air temperatures and soil temperatures are warming at the same rate

September 2025 was the third warmest on record

Persistently high land and sea surface temperatures reflect the continuing influence of greenhouse gas accumulation in the atmosphere 🌍⚒️🧪🌊

Thank you Penny!

2) Soil temperatures monitored across the UK since 1959 show the same long-term trend with slightly smaller variations from year-to-year as the soil integrates weather fluctuations.

Should we use soil temperatures more for climate monitoring?

Two sources of corroboration for the UK temperature series are:

1) Independent reanalyses such as ERA5 (1950-2024) and 20CRv3 (1884-2015), which show the same trends and variability in UK temperature as the official Met Office series.

The @copernicusecmwf.bsky.social climate monitoring application #Climate Pulse has been updated. Same climate monitoring data with new features and better layout. 🌏🌊⚒️🧪

User feedback always welcome so let us know what you would like to see updated in the next version:

Monitoring changes in UK temperature

To (almost) no-one’s surprise, multiple sources of data agree on the long-term trends in UK temperatures.

More like ‘borrowed’ than ‘robbed’! 😉

Very happy that so many people are borrowing the stripes concept to start important environmental conversations.

The online version had an extra sentence. It is disappointing that the topic cut from the print edition was on the contribution of women observers:

"Although many rainfall recorders were men, there were also significant contributions from women, such as Lady Bayning in Norfolk in the 19th century."

edhawkins.org
Our paper on historic rainfall observers was discussed in The Times weather column this week, highlighting the role of the thousands of (often) volunteers who dedicated decades to taking detailed measurements of the weather.

Yep - remember that! I think I vaguely recall the satisfaction of seeing (from Adrian Simmons?) the brand new ERA-Interim agree with CRUTEM back in 2009/10 times.

Aside: Perhaps @copernicusecmwf.bsky.social should produce country-level averages for many different climate variables as a dataset from ERA5 or ERA5-Land? There may be 'political' reasons for not doing so but it would be valuable, especially for nations without extensive monitoring capabilities.

There are still some who try to dismiss weather station thermometer observations as being biased & unrepresentative of the true changes in temperature. The fact that the trends and variability match so well between these two datasets helps demonstrate that we are reliably measuring ongoing changes.

The @metoffice.gov.uk use weather station observations to reconstruct changes in UK average temperature since 1884.

@copernicusecmwf.bsky.social produce the ERA5 reanalysis which reconstructs global weather every hour back to 1950 using a weather forecast model.

Their estimates agree. Just sayin'.

Well done to the Warming Stripes La Rochelle team!

Starting climate conversations in France! 👏

There are still many volunteers who contribute manual daily rainfall observations and their sites are inspected to ensure reliable measurements. The proliferation of automatic weather stations is really helpful for real-time monitoring & nowcasting but perhaps not yet for long-term climate records?
