🚨Our new paper introduces the #AirQualityStripes – a visual tool to show how outdoor air pollution (PM2.5) has changed in 🌍 cities since 1850. Inspired by the iconic #WarmingStripes. Led by @kirstypringle.bsky.social & @jimmcquaid.bsky.social 🔗 airqualitystripes.info 📄 doi.org/10.5194/gc-8... 🧵👇

Summer 2025 strongly affected the Gries Glacier in the Swiss Alps which lost ~6m of ice thickness in just a few months. These Copernicus Sentinel-2 satellite images show snapshots of 26 August 2025 and of 9 years earlier put the recent loss of ice in perspective.

I'm a really big fan of these "storyline" approaches to uncertain forecasts – such a simple way to communicate quite a lot of detail and I think in a way that makes sense to many. Hope to see more of these on TV

Jared’s pictures also show why meteorology is such a dynamic and interesting discipline - really awesome.

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...

Spain has just announced it’s joining the Global Initiative for Information Integrity on Climate Change. "Disinformation not only creates confusion and spreads fake news; in the context of the climate emergency, it also puts lives and property at risk. Climate misinformation kills" buff.ly/cixOfB9

In 2024, all glaciated regions on Earth lost ice for the third consecutive year. That’s 450 Gt gone: enough to fill 180 million Olympic swimming pools. This added 1.2 mm to global sea levels. Read the #StateOfWater report 🔗 https://bit.ly/469OBWU

Unvovering our climatic history is fine with Data Rescue - DARE. While in the western world DARE is uses for old ship logs and station records of the 19th century, for the developing world DARE is required for data of only decades old. The way forward here is AI. www.nature.com/articles/d41...

Peace starts with us. The European Union was created to turn a divided continent into one of dialogue between 🇪🇺 countries, cooperation, and solidarity. Peace is not just part of our past — it remains our mission. Today and every day. #PeaceDay

2024 marked the sixth consecutive year of an erratic hydrological cycle. Continued investment in water resources monitoring and stronger collaboration in data sharing are vital to closing global monitoring gaps. Read the #StateOfWater Report 🔗 https://bit.ly/469OBWU

What you are seeing: a before-and-after of the Berg Lake’s drainage changing as Steller Glacier retreats, forcing the water to find new drainage routes - increasing the risk of sudden and destructive glacial lake outburst floods (GLOFs). This is why #Glaciers2025 matters.

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.

Storm Augustin, named by MeteoSwiss, is expected to bring some very heavy rain in the next couple of days to parts of Switzerland and northern Italy, which could lead to flooding

Glaciers are retreating everywhere - also the Skeiðarárjökull glacier in southern Iceland. The glacier’s retreat is visible in these Copernicus Sentinel-2 images, acquired in July 2017 and July 2025. The 2025 image shows the 2017 glacier terminus in red. Source: Copernicus image of the day.

Europe has seen an intense heatwave since late June with temperatures exceeding 40 °C. The Copernicus satellite images of 22 June and 2 July show the rapid loss of soil moisture around Châlons-en-Champagne in northern France in the heatwave. Blue is wet, yellow and red indicates moisture stress.

One of the challenges to understanding climate change is that extremes don't necessarily change in the same way as averages. In Western Europe, for example, the hottest day of the year is warming noticeably faster than the average summer day.

The combination of crowd sourced meteorological data with the weather station data of the Dutch met office gives detailed maps of today’s developing heat. It clearly shows the urban areas warming faster than the rural surroundings.
