A few days before Christmas and near record high temperatures are occurring around the North Pole in the #Arctic 🎅🥵

Line graph time series of daily Arctic temperatures north of 80°N latitude for every year from 1958 through 2025. There is a long-term warming trend for every day of the year and a clear seasonal cycle. 2025 is currently much warmer than average.

I would also argue that in France and Germany the green pressure undermined nuclear industry. Is that fair? Remind me why Nuclear is not a good solution in your opinion. I always felt that the French post second world nuclear path was a good one and never understood why France deviated from this?

"Wave bureau" A short movie for Ocean Physics and Climate Change #GEOL0022 by Fjodors Aleksejevs with amazing photography, music and humour reminding of me of the late David Lynch www.youtube.com/watch?v=5uTB...

Another gem from my wonderful students in Ocean Physics and Climage Change #GEOL0022. This time it is by Ceren Baylan singing an ode to the Gulf Stream with her soothing guitar. Perfect way to start a relaxing week end www.youtube.com/watch?v=PRjS...

Our new article explores how @copernicusmarine.bsky.social uses data from EUMETSAT-operated Sentinel-3 satellites to support the ocean sector.

From algae monitoring to sea level & ice forecasts, @mercatorocean.bsky.social’s Pierre-Yves Le Traon explains why these services are vital: bit.ly/4pcwp64

Our paper led by Peigen LIn on the related topic of Arctic Beaufort Gyre fresh water accumulation is available here www.nature.com/articles/s41...

a, Geographic map of the Arctic Ocean with an enlarged view of the study region (black box). The schematic BG is marked by the yellow circle. The BG region is delimited by 130–180° W, 81° N and 300 m isobath (thick purple line), over which area averages (± standard errors) are computed, shown in b–d. The bathymetry from the International Bathymetric Chart of the Arctic Ocean v3 is coloured, with the isobaths of 40, 70, 150, 250, 500 m in grey, and 100 and 300 m highlighted in black. b, The annual mean BG DOT (m). c, The annual mean BG FWC (m) and volume (×104 km3) estimated using the historical hydrographic data (FWC1, magenta) and using the DOT + GRACE data (FWC2, green). d, The annual mean BG thickness anomalies (m) relative to 2003 of the layer from the surface to the top of the cold halocline (yellow), the CHL beneath this (purple) and the sum of the two layers (orange). The standard error, shown by the bars, is the standard deviation divided by square root of the degrees of freedom, where the degrees of freedom for each year (ranging from 12 to 71) are computed using an integral timescale of three days for the hydrographic data and one month for the monthly satellite data. The dashed lines are the linear trends in the early and late periods, and the black lines in b and c denote the linear trends of DOT and FWC1 over the full study period, respectively. The trends were computed using the time series of annual mean variables.

Scary stuff showing that the UK is in the range of this AMOC tipping point induced large cooling area! @ucl.ac.uk and the UK is working on this topic with various projects already funded but also in the pipelines.

Is the Atlantic Ocean circulation close to tipping?
Hear the latest science as I presented it last month at the ATLAS25 event in Helsinki.
Let me know if anything is unclear, or if you see good reasons why your government shouldn't immediately act on this. 🌊

BBC Under Attack: Pot and Kettle Special

The new Private Eye is out now.

A photo of the front cover of issue 1662 of Private Eye magazine with the caption "on shelves now." The front cover reads “BBC Under Attack: Pot and Kettle Special” and shows Broadcasting House with speech bubbles coming from the building. The quotes include “Donald Trump says we broadcast fake news!”, “Nigel Farage says we’re totally biased!”, “Boris Johnson says we’re liars!”, “The Daily Mail says we’re peddling conspiracy theories!”, “Kemi Badenoch highlights poor leadership!”, “The Daily Telegraph says we’re editing for political purposes!”, and “Liz Truss says we’ve done huge damage to the country!”

Average temperature departures by month in the #Antarctic since the year 1940.

Data from @copernicusecmwf.bsky.social ERA5 reanalysis.

Line graph time series of monthly mean surface temperature anomalies for the Antarctic region only. Every month is shown from 1940 to 2025. There is a long-term warming trend in all months of the year, but less obvious than the other regions.
