Happy New Fear! The new Private Eye is out now.

Comparison of monthly temperature anomalies in the #Arctic versus the #Antarctic so far in 2025 (yellow lines). The other lines show the monthly anomalies for years from 1940 (blue) to 2024 (red). Note the long-term trends through the color gradient. Data from @copernicusecmwf.bsky.social ERA5.

One of my highligths of 2025 was to listen to the conference by @cedricvillani.bsky.social and interview him this summer in Crete Hania as part of the #FestumPi series of conferences. His talk entitled "Is AI the doom of ecology?" is a must watch www.youtube.com/watch?v=3pFT...

"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... This one deserves a price! @es-ucl.bsky.social @ucl.ac.uk

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...

"War is peace. Freedom is slavery. Ignorance is strength" -- George Orwell (1949)

And how many witches we’d be burning.

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

Amazing Ocean Physics and Climate Change #GEOL0022 presentation South Park style by Samirah Khatun...Very timely in view of risks of AMOC tipping if beaufort Gyre Arctic freshwater released to North Atlantic. Any resemblance to real persons is purely coincidental 😅 www.youtube.com/watch?v=P6qt...

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. 🌊 youtu.be/ULJXqOZuY-8

1/3 A lot of people are contacting me to do a PhD in polar remote sensing and modelling. Here are two advertised PhD studentship led by colleagues of mine that are super cool and in collaboration with me and UCL @es-ucl.bsky.social

Average temperature departures by month in the #Antarctic since the year 1940. Data from @copernicusecmwf.bsky.social ERA5 reanalysis.

BBC Under Attack: Pot and Kettle Special The new Private Eye is out now.

One day, when this national nightmare is over and speaking up has no consequences, everyone will claim they were against this.

#GEOL0022 all you ever wanted to know about the key role of the Southern Ocean in our climate system summarized in a great 5 minutes video by one of my students www.youtube.com/watch?v=f_zZ... Great work Billy Liu 👍. See credits at the end for inspiration from @jbsallee.bsky.social and others...

As part of my ocean physics and climate change module #GEOL0022 students put together quick summaries of my previous class. Here is one of these presentation that really stand out due to the creativity and acting talents of its author James Ge. Great job James! www.youtube.com/watch?v=A2MQ...

A new year of teaching Ocean Physics and Climate Change @ucl.ac.uk @es-ucl.bsky.social and the students are already producing some gems as part of their flipped classroom assignments. Radiative Forcing by Elizabeth Goodwin: www.youtube.com/watch?v=u8bT...

I wrote a post (with ChatGPT's help) on my stepdad's mathematical theories. Interested to hear your thoughts... www.linkedin.com/posts/michel...

Very thought provoking talk from a famous maths professor Jean-Louis Krivine with a possible explanation of the paradoxes of physics, the Curry–Howard correspondence, the brain and much more...Physicist friends and colleagues buckle up! English subtitles available www.youtube.com/watch?app=de...

Wow. Check this out. Politicians actually trying to solve problems can achieve a lot! www.washingtonpost.com/climate-solu...

Let me rewatch The Day After Tomorrow to see what to expect.

1/n Some thoughts from me on the 'good news' story about slow down of Arctic sea ice decline that came out in the Guardian last week following a paper published in GRL www.theguardian.com/environment/...

The extraordinary loss of August #Arctic sea ice thickness over the last four decades... Data available at psc.apl.uw.edu/research/pro.... More info at climatedataguide.ucar.edu/climate-data...

eartharxiv.org/repository/v... In our new preprint we describe in detail the software & workflows behind www.SewageMap.co.uk! One for the open environmental data nerds out there :) 💩 🧑‍💻 🏞️

Last but not least session for me at #LPS25 with Rosie Willatt from @es-ucl.bsky.social telling us about up future opportunities in polar earth observation and upcoming satellites 🛰

Great talk on our safe travel on sea ice projects in Inuit Nunangat by Neil Brubacher in collaboration with the amazing Inuit social enterprise #smartice #lps25 @neilbrub.bsky.social

🚧Urgent notice to all SSMIS product users 🚧 We've just been informed that #SSMIS from the US #DMSP satellite will stop to be distributed on Monday 30/06/2025. Consequently, we advise SSMIS only-based #SeaIce products users to urgently change. More information: osi-saf.eumetsat.int/community/st...

Exciting session this morning on large langage models application to Earth Observations #lps25 with Solene Debuysere and Madleen Bultez first #DIVA #controlnet

So far this week: ❌ SSMIS data halted (think sea ice, snow, hurricane, ice sheet monitoring, etc) ❌ climate[dot]gov removed and redirected to... ❌ NOAA Climate homepage, which was modified (e.g., removed Climate Stripes and Climate Ready Nation references) ❌ false bills to ex-probationary employees

Great overview presentation by Sarah Kacimi on altimetry for sea ice retrievals and remaining challenges in both Arctic and Antarctic. Note the empty desk as the presentation had to be remote / recorded #lps25

We’re now celebrating 15 (!) years of #cryosat2 with 80000 orbits around the Earth and counting. We’re hoping for at least another 3 years of amazing data. @esa.int @cpom-uk.bsky.social

Wtaf?
