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 🌡️🌏🧪⚒️

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 For more insights: climate.copernicus.eu/climate-bull...

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. More info ⬇️​

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.

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. ➡️ www.ecmwf.int/en/about/med...

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 🌍⚒️🧪🌊 For more: climate.copernicus.eu/copernicus-t...

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: pulse.climate.copernicus.eu

Out now! Version 2.0.0 of the Global land surface meteorological observations dataset (1755–present) is available in the #C3S Climate Data Store (CDS). Updated in situ coverage thru 2024 plus enhanced and consolidated data from worldwide sources. 🔗 cds.climate.copernicus.eu/datasets/ins...

We have a new paper out in @science.org today, led by Helge Goessling from #AWI: The recent global temperature surge in 2023 was intensified by a record-low planetary #albedo 👉 doi.org/10.1126/scie... @thomasjung.bsky.social @ecmwf.bsky.social This is what we found (🧵1/8)

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. www.ft.com/content/67ec...

🌡 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.

Everybody is talking about heatwaves these days. This morning @copernicusecmwf.bsky.social published a new app about thermal stress and its time evolution. You can access the app here: thermaltrace.climate.copernicus.eu & read more about it here: climate.copernicus.eu/thermal-trac...

Right then... 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 /thread/

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.

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. Read more in our European State of the Climate report: climate.copernicus.eu/esotc/2024 #CopernicusClimate

🚨 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 🧪⚒️🌊

Mais cette différence Est/Ouest est assez « inhabituelle ». « D'après les projections, le changement climatique devrait accentuer à l'avenir un contraste Nord-Sud en Europe, avec un assèchement accru dans le Sud et des conditions plus humides dans le Nord », a expliqué @carlobuontempo.bsky.social

L’Europe est le continent qui se réchauffe le + vite. Et 2024 a été l’année la + chaude jamais enregistrée. Avec un contraste très marqué de conséquences : un climat très chaud et sec à l’Est, et très humide à l’Ouest, montre le bilan @copernicusecmwf.bsky.social www.francetvinfo.fr/environnemen...

This is a wonderful and very reactive new version of the ERA explorer app. I hope you will enjoy using it.

Last Tuesday, I was set to give a talk on 'climate change in the Northeast' at a retirement home but had to cancel due to hourly job threats. After nearly two weeks of overwhelming uncertainty, today it happened. I was fired from my dream of working at NOAA. I'm so sorry to everyone also affected.

ECMWF invites tenders for developing an operational climate service for agriculture, delivering climate data on a global scale to support decision-making and crop management. #C3S Apply by April 15, 2025! climate.copernicus.eu/c3s2414-oper... @carlobuontempo.bsky.social

New record alert on the #StateOfClimate front: Our colleagues at @copernicusecmwf.bsky.social confirm that January 2025 was the warmest January globally on record. This comes despite the onset of #LaNiña, a phenomenon that typically brings temporary cooling. climate.copernicus.eu/copernicus-j...

The 2025 temperatures have got a head start. With four days to go, it is virtually certain that January will become the warmest ever measured. And this is despite the ongoing La Niña in the Pacific. Data from pulse.climate.copernicus.eu @copernicusecmwf.bsky.social

As many others, since January 20 I am no longer active on twitter/X. You can find me here or on Linked-in (www.linkedin.com/in/carlo-buo...), instead.

We have lost 8200 km3 of global glacier ice since 1976. The International Year of Glaciers’ Preservation, led by @wmo-global.bsky.social & @unesconow.bsky.social, aims to raise awareness & advocate action to mitigate the consequences of glacier melt. Find out more: bit.ly/4h55fda

As the climate data for 2024 continues to arrive, I've updated my graphic showing changes in various climate indicators for the recent past, and the last 2000 years. Most notable change is a big jump for tropospheric temperatures (TLT) in 2024. [Sea level and land humidity data not yet available.]

«Je suis à court de métaphores pour expliquer l’ampleur du réchauffement», s'alarme le chercheur @carlobuontempo.bsky.social. 2024 est la première année à dépasser le seuil symbolique des +1,5°C par rapport à l'ère préindustrielle (19e siècle), alerte l'observatoire européen Copernicus. Décryptage.
