Several international organisations all released their global temperature updates today. In addition to our @copernicusecmwf.bsky.social Global Climate Highlights, here’s a thread with resources from WMO, the Met Office, Berkeley Earth, NASA, NOAA and more 📈🌡️⬇️

In the @copernicusecmwf.bsky.social Global Climate Highlights 2025 report we used #dataviz to present its key messages and bring them to a wider audience. This first example shows daily temperature anomalies from 1940 to 2025 and it was inspired by the work of @erwanrivault.com (BBC)

Globally, no single day in 2025 was cooler than its 1991-2020 average. climate.copernicus.eu/global-clima...

For @copernicusecmwf.bsky.social Global Climate Highlights, I used our Thermal Trace app to investigate heat and cold stress in 2025 🥵🥶Half the world saw more strong heat stress than average while most regions saw less cold stress GCH: tinyurl.com/gch-2025 Thermal Trace: tinyurl.com/thermal-trace

Our latest @copernicusecmwf.bsky.social Global Climate Highlights 2025 report is out now. 2025 was our planet's third-warmest year on record ⚠️ and 2023–2025 stands apart from all previous years. Why? To find out, I encourage everyone to explore the report: climate.copernicus.eu/global-clima...

SSHWS category is assigned using ONE value: the maximum wind 10 meters above the ocean surface averaged over 1 minute. A hurricane is not a point. Its size (extent of its wind *field*), forward speed, rainfall, potential storm surge, and the landscape it traverses all factor into its impacts. [3/5]

As a meteorologist with a 20-year obsession with hurricanes (thanks to Charley in 2004), who has done research and diagnostics on tropical cyclone forecasting and now works in climate science / learning about attribution, this is a very interesting thread about Hurricane Melissa ⬇️🧵🌀

I was lucky enough to spend some time recently learning how to make fused glass art - and was so excited to use @annalombardi.bsky.social’s beautiful data viz from the cover of #ESOTC2024 as inspiration for a glass creation!

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

An interesting comparison of this summer so far with the UK’s infamous summer of 1976 ☀️🥵 This year’s June heat was more widespread across Europe + the UK saw larger temperature anomalies this June, but drought in 1976 was more prolonged and widespread with more extreme water use restrictions 💧

Why are Europe and the Arctic warming twice as fast as the global average? Explore the science behind these regional trends in our latest article. climate.copernicus.eu/why-are-euro... #CopernicusClimate

Construction of ECMWF’s new headquarters in Reading, UK, has begun. Yesterday’s groundbreaking ceremony was led by Lord Vallance, the UK Minister of State for Science, Innovation and Technology. Find out more here ➡️ www.ecmwf.int/en/about/med...

Exceptional Mediterranean water temperatures in June reduced nighttime air cooling along the coasts & increased humidity, worsening heat stress impacts - some coastal areas saw 10-15 tropical nights (when the temperature doesn’t drop below 20°C) last month, when they’d typically see none in June 🥵☀️🌙

Two significant heatwaves in Europe in June meant that many people experienced more heat stress days than average: 'very strong heat stress' experienced across a lot of southern and western Europe, and part of Portugal saw 'extreme heat stress' 🥵 Find out more: climate.copernicus.eu/heatwaves-co...

We have taken the ensemble version of the Artificial Intelligence Forecasting System (#AIFS) into operations! It will run side by side with the traditional physics-based Integrated Forecasting System (IFS). Find out more here ➡️ www.ecmwf.int/en/about/med...

We have just had the warmest June for England, although it was still warm but less extreme elsewhere. It was very sunny and dry in the East and wetter and cloudier in the West. Here is a summary of the past 12 months weather/climate for the UK. #dataviz

1°C of global warming does NOT mean that heatwaves 'just' get hotter by 1°C. Over large parts of the UK, global warming means that heatwaves are 3-4°C warmer, with worse consequences for people and ecosystems.

Is it hot right now? YES!! (In most of Europe anyway) 🥵🥵🥵 Loving these new web applications developed for the UK 🇬🇧 by @roostweather.bsky.social and @edhawkins.org and Spain 🇪🇸 by @dargueso.bsky.social and AUS 🇦🇺 (original) by @mlip.bsky.social 🌍🧪⚒️🌡️📈 Links: istheukhotrightnow.com hoyextremo.com

The tongue of Rhone #Glacier ten days after my last visit. Can you guess how much ice melted away? 1️⃣ meter in terms of thickness! 1️⃣0️⃣ days... And that's just the beginning of the summer season. We know the times are bad for the ice, but still it is hard to accept these numbers!

😔

The alps have warmed extremely - as can be seen here in the data from #Innsbruck. Warm years are dominant since the 90s, cold years disappear. Massive glacier melting is only one consequence. Weather Obs started very early here, Maria Theresa was still alive. #showyourstripes #climateaction

🌍🌐 AI is reshaping weather and climate modelling - also within DestinE at ECMWF. Discover our new AI page and explore how #ECMWF and its partners are developing ML-driven models and AI-based software solutions, which will boost DestinEs capabilities ➡️ destine.ecmwf.int/ai-in-destine/

On the day the @metoffice.gov.uk publish a new paper showing a rapidly increasing chance of 40°C days in the UK, the GFS produces a forecast ensemble member showing 43°C in a couple of weeks time. This is an extremely unlikely outcome but highlights that these types of temperature are now plausible.

Tailoring is essential to scaling up climate services eg weather & climate info for children & youth, who must be stakeholders, says Emma Visman of @savechildrenintl.bsky.social #ECCA2025 #ClimateServices #Health #Children #Youth #NationalFramework #Scaling #DisasterRisk

Day 3 at #ECCA2025! We are live from Lavatoio Room, discussing strategic R&I priorities for climate adaptation. Experts are soon splitting into breakout sessions around the tables to share their insights. Collaboration in action! 🤝 #MakeItReal #Impetus4Change #I4C #ClimateAdaptation

Day 2 at #ECCA2025 gets underway with Philippe Tulkens setting out EC's priorities for climate adaptation: 'We need your expertise to be part of the mission ... get us closer to success!'

How much would weather forecasts gain from more in-situ observations in some countries? Experiments we have carried out for the UN’s Systematic Observations Financing Facility (SOFF) show that the benefits would be significant.

I’ll be at the European Climate Change Adaptation #ECCA2025 conference this week in Rimini supporting our EU project I-CISK, which has been co-creating human-centred, tailored climate services with partners and decision-makers in seven different countries in Europe & beyond 🌍🌐📈

Some forecast models are showing the potential for record-breaking heat in the UK later in June 🌡️ Ensemble forecasts can help us better understand the extremes of the current climate. @hayleyjfowler.bsky.social, Paul Davies and I wrote about this last year theconversation.com/the-climate-...

💧Northern & central Europe saw drier-than-average conditions in May, wetter-than-average in southern Europe & western Russia. March to May 2025 saw Europe's lowest spring river flow since records began in 1992. Get the details in the #C3S Climate Bulletin 🔗 climate.copernicus.eu/sea-ice-cove...
