January 2026 saw a strong contrast in extreme temperatures across the globe.
🌨️ North America:
Nearly all of Canada, and most of the USA, experienced 'very strong cold stress' (feels-like -27°C or lower).

Maps and charts shape how we see the climate crisis. Visualising Climate asks how we can design visuals that inform without oversimplifying and inspire action with integrity.
Imagine new ways forward.
#SeeingClimate
It's official 🎉
Visualising Climate 2026 is here! visualisingclimate.com
First international conference of its kind, it'll bring together artists, scientists, journalists all moved by the same desire to better communicate our changing climate 🌍
🗓️ Join us in Bologna, Nov 4-6

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.

A figure from the global climate highlights report (figure 11) showing two maps of the globe, one with anomalies in the number of days with at least strong heat stress, and the other with anomalies in the number of days with at least strong cold stress, in 2025.
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

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! Grateful to work with someone so wonderful, supportive and inspiring ☺️ ☁️☀️
I had a lot of fun making these - I find your beautiful data viz so inspiring, both for storytelling / climate communications and for creating art 😄🥰 a pleasure to work with you always @annalombardi.bsky.social!
NWS Norman just issued their 1,112th Severe Thunderstorm Warning this year, which is now ~12% higher than their previous year's max of 988. (Glad VTEC implemented 4 digit tracking event numbers!)

During the heatwave in western Europe in August, maximum feels-like temperatures reached up to 45°C in France, 47°C in Portugal, and 49°C in Spain – the threshold for ‘extreme heat stress’ is 46°C 🥵

Met Office stats confirm summer 2025 is officially the warmest summer on record for the UK.
The UK’s mean temp of 16.10°C surpasses the previous record of 15.76°C and pushes the summer of 1976 out of the top 5 warmest summers.

Rising temperatures mean heat stress is becoming a growing health risk — especially in Europe. What causes heat stress and how do we monitor it? Explore the science in our article

Ever wondered how heat stress is changing where you live? With the new Thermal Trace app from #CopernicusClimate and #ECMWF, you can explore “feels-like” temperatures, track heat stress categories and thresholds, and visualise interactive charts for your city.
In recent days, southern Europe has faced heatwaves ☀️ Thermal Trace maps show feels-like temps reaching 46°C – the ‘extreme heat stress’ threshold – in Spain on 14-15 August and 47°C on 11-12 August 🥵 In SW France, feels-like temps reached 45°C – that's up to 14°C above average! 🌡️
