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 🌍⚒️🧪🌊

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'.

The records observed in the past years were often “so striking that we’ve occasionally had to stop and triple check the data to make sure it was accurate” says scientist J. Nicolas.
Very nice @data.ft.com piece about this 🤩 viz with
@copernicusecmwf.bsky.social data.

🌡 Third-warmest August globally, 1.29°C above pre-industrial level, 0.49°C above the 1991–2020 average for the month. Western Europe saw major heatwaves, mostly in the Iberian Peninsula and southwest France. Third-highest sea surface temperatures on record at 20.82°C.

Happy to have contributed to this paper. Forcing data NRT availability (or lack thereof) is an important limiting factor for the sustained mode of production of climate data and information. We need dedicated resources in support of climate forcing research & operation.

Annual updates to ‘climate forcing’ data sets would allow simulations to keep pace as global warming accelerates.

The patterns of temperature anomalies across the #Arctic region over the last 12 months...

Data using @copernicusecmwf.bsky.social ERA5 reanalysis with a 1981-2010 reference period.

Twelve polar stereographic maps showing 2-m air temperature anomalies in the Arctic from July 2024 to June 2025. Blue shading is shown for colder anomalies, and red shading is shown for warmer anomalies. All months are warmer than average overall. Anomalies are computed relative to a 1981-2010 baseline.

I do enjoy radiolab. It use to be much better some 10 years ago but the most recent episodes seems to suggest a possible come back to that old amazing level. On politics TheRestIsPolitics is great though.

The paper is so absurd that you are bound to think this is a joke to orchestrated to make a point (of some sort). Is there any chance this is the case?

Tropical nights are on the rise in Europe, offering little relief from daytime heat. The Copernicus Climate Change Service tracks these trends to help keep communities informed and safe.

🚨 The 2024 European State of the Climate (ESOTC) was released today.

There are absolutely beautiful data visualizations throughout this report, but they also reveal some very alarming statistics of climate trends and extremes.

Check it out: doi.org/10.24381/14j... #ESOTC2024 🧪⚒️🌊

Graphic showing trendss in climate indicators, where climate indicators show the long-term evolution of severeal key variables that are used to assess global and regional trends in a changing climate. These include sea surface temperature, ocean heat content, sea level, temperature, greenhouse gases, sea ice, glaciers, and ice sheets.
