🟥 We've started a new project under the @copernicusecmwf.bsky.social (C3S) for downscaling CMIP6 Climate Projections using #AI techniques to complement the @wcrpclimate.bsky.social CORDEX Regional Climate Models Simulations.
Led by our regular partner @ifca.es.

Climate change is accelerating, with the past 10 years the hottest on record. #C3S Director @carlobuontempo.bsky.social calls attention to this rapid evolution, emphasising the importance of scientific data and knowledge to inform action.

Latest bulletin from @copernicusecmwf.bsky.social shows:

October 2025 was the third-warmest October globally, 2025 on track to place second or third, possible tied with 2023, and behind 2024, the warmest year on record

Latest #Climate data shows a podium finish for 2025

We are in the decade where the 1.5°C limit is likely to be exceeded, highlighting the accelerating pace of climate change

Average global temperature for 2023–2025 is likely to exceed 1.5°C, the first three-year average to do so 🌡️🌏🧪⚒️

New in the Climate Data Store (CDS): the ERA5-Drought dataset, with monthly meteorological drought indicators across accumulation windows from 1, 3, 6, 12, 24, 36 & 48 months from 1940 to today. Supports both deterministic & ensemble products on a 0.25° grid.

Global sea surface temperatures continue to cool off as we head into La Nina. 2025 (for the 1st time in 3 years) will not set a new global temperature record.

It's the steady longer-term warming that is cause for concern. It will continue until human carbon emissions cease.

Truth is bad enough.

😂 I don't see much future in this technology. If the uptake is significant the capture potential is ... self-limiting :-)

That's so cool! It reminds me of something rmets.onlinelibrary.wiley.com/doi/10.1256/... ;-) . it is quite incredible to see what 20 years of technical development can mean for our ability to sense the world around us.

The 2024–2025 State of Wildfires report shows a paradox: less land burned, but record carbon released.

ECMWF scientists analysed what drove wildfire events and generated air-quality datasets.

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.

🌡 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.

A quick review of the DOE's new 'critical review' of climate science. Whether it's worth a formal community response - I'm still not sure, but here's my first thoughts

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?
