#ESA and #CIMR #L2PAD team met at ICM-CSIC, Barcelona, to discuss Level-2 algorithms for the Copernicus Imaging Microwave Radiometer mission
Launching in 2029, CIMR will deliver hi-res data on polar sea ice, oceans and land
Led by MET Norway with @esa.int support.

Which whale species did I see? Leatherwood et al. (1982, p. 10) is hard to beat...

Reflection of a sunrise in a puddle

It’s often when you have the fewest seconds to reach the Metro before it leaves that you find a puddle, a sunrise, and a tree all in the same view. But you have no choice. Freewill is an illusion.

I'll be talking this afternoon about challenges in interpreting and making fair comparisons of sea ice age between climate models and observations, and demonstrating one way to resolve this using a common definition of sea ice age (paper out soon).

@signeaaboe.bsky.social kicking off the Sea ice Age (SAGE) project webinar to discuss current challenges and opportunities in using age to monitor sea ice change.

Lucky you - It's not too late to register for tomorrow's daybinar on sea ice 😉

So scarry - loss up to 30cm/year water is a lot 😱

Grafen viser akkumulert gjennomsnittstemperatur for 2025 hittil – samt 2014 og 2002 i konteksten av alle år fra 1901. Altså temperaturgjennomsnittet fra januar til og med hver måned. Tallet for august viser gjennomsnittet for perioden fra januar til august.

🌡️ Så langt i år er 2025 det varmeste året registrert, med 2014 og 2002 like bak.
– Gjennomsnittstemperaturen for perioden januar til august har aldri vært høyere fra vi startet å måle i 1901, og fram til i dag, sier klimaforsker på MET, Reidun Gangstø.

Stem på havet

“I didn’t hear the usual grinding of ice” When a Norwegian vessel reached the North Pole this week, the scientific team made an alarming discovery.

"There was still sea ice, of course, but our vessel had little trouble navigating through it, thanks to open leads and channels. That’s what struck me most: the ease of access through what used to be a far more ice-covered region,” Knies writes.

According to ERA5 Reanalysis, this was the warmest summer on record for the United Kingdom. Seems bad. 🔥🔥🔥

3 pilars for a greener future: Phase out fossil fuels: Today, Norway is one of the world’s biggest fossil fuels producer. Transitioning to renewable energies will make Norway’s economy more sustainable. Protect nature: With forestand biodiversity disappearing fast, Norway’s immense beauty needs to be protected. Fight poverty: The number of people in poverty is rising. We need to tax the rich and ensure a guaranteed minimum income for those with less.

Norway, go vote for your future!

The Green Party in Norway is offering a progressive future, with a strong Green voice that will:
❌ Phase out fossil fuels
🌳 Protect nature
🏠 Fight poverty on a local, national and international level.

💚 Good luck to @mdg.no!
🗳️And to our friends in Norway: go and vote on 8 September.

🌍 Have you heard of the ESA Climate Change Initiative Toolbox?

The comprehensive Python package gives researchers seamless access to decades of satellite climate data.

Give it a try 👉https://climate.esa.int/en/data/toolbox

📊 Access research-ready global climate data records!
On our updated website, you can find a number of code examples & extensive documentation of how to use our Toolbox and get fast access to it via our Jupyter Lab. Check out the free-of-charge environment here: climate.esa.int/en/data/tool...

Following #SSMIS impredictable data provision, in order to ensure our users with a reliable service, we are now basing our Sea Ice Index on AMSR-2-based Sea Ice Concentration product.

In August 2025, the #SeaIce global extent was 8.4% below 1991-2020 mean. Since the begining of record (1978):
- #Arctic, 8th lowest monthly mean, with 12% less extent (-823.904km²)
- #Antarctic, 3rd lowest monthly mean, with 7% less exent (-1.264.062km²)

Isebreforsker Thomas V. Schuler måtte bruke en pall for å utføre vedlikehold av instrumenteringen på isbreen på Kongsvegen som ligger ca. 500 moh. Vanligvis er det knapt issmelting på dette punktet, men i fjor hang instrumentboksen 2 meter over isoverflaten på grunn av ekstrem smelting. Foto: Shin Sugiyama/ HU Sapporo.

I 2024 smeltet isen på Svalbard i et tempo vi aldri før har sett.

På seks uker forsvant 61,7 gigatonn med is fra breene på Svalbard. Det er mer enn det forsvant fra Grønland, selv om Grønlandsisen er 50 ganger større 🧊

– Det var helt ekstremt, sier Thomas V. Schuler.

Warming and thawing permafrost is confirmed by data from nearby monitoring stations. 2025 will be another bad year for the permafrost in Svalbard. Still some weeks left of the thawing season..

Witnessing the rapid and extensive thawing of permafrost in Svalbard is truly impressive but deeply concerning

Temperaturen under den varmeste 14-dagers perioden i juli 2025 er den desidert høyeste som er registrert for Norge
