Glaciologist @matthias-huss.bsky.social shows that the centre of the Great Aletsch glacier in Switzerland (the biggest in the Alps) lost 6 meters(!) of thickness just this summer. "No words...", he adds on LinkedIn.

8 years ago, I tweeted side-by-side maps from NASA GISS showing global temperatures in 1976 and 2018 – both hot summers in the UK. It subsequently went viral and was printed in the Daily Mail! The 2026 version is stark. Two locally extreme summers separated by 50 years of global climate change.

Projection has become reality 22 years ago, Christoph Schär et al. published a landmark paper in Nature explaining that the 2003 heatwave was a harbinger of things to come. The study featured an iconic figure - shown in countless lectures - illustrating how outlandish the event was at the time

Looking at the recent #ECMWF forecast of zonal mean zonal wind at 10°N and 10 hPa #PolarVortex, it seems that the split #SSW was seen by the model initialised on Feb 23, literally 10 days before it is happening. This corresponds to the current skill of subseasonal to seasonal #S2S forecast systems

🚨New preprint alert!🚨 Was the strengthening of the Northern polar vortex in 2024/2025 associated with the Hunga Tonga #volcano? Our research using models and obs links descending volcanic water vapor plumes to the record-strong 2024/2025 Northern #PolarVortex egusphere.copernicus.org/preprints/20...
A: Zonal mean weighted average for latitudes between 60–90◦N of water vapour volume mixing ratio (VMR; shading and
contour of 1 ppmv; monthly) anomalies for the extended winter 2024/2025 from MLS. Anomalies are expressed as differences with respect to the climatology for the period 2006–2020. Due to missing data, water vapour is visualized as monthly anomalies with interpolated gaps. Due to a retrieval artifact in the 10–8 hPa layer we smoothed the data vertically.

B: The average (east-west) zonal wind for 60◦N at 10 hPa for the extended winter 2024/2025 (OW3) in MERRA2. This is near the peak of the polar jet maximum.
