Like the majority of our #SeaIce products, the Sea Ice Index is currently based on data from #JAXA 's #AMSR2 sensor. This sensor is being operationally replaced by its successor, #AMSR3, and we are currently adapting our products accordingly. For more details: osi-saf.eumetsat.int/community/st....

In June 2026, the #SeaIce global extent was 7% below 1991-2020 mean. Since the beginning of records (1978): - #Arctic, 6th lowest monthly mean, with 5% less extent (-567,575 km²) - #Antarctic, 6th lowest monthly mean, with 8% less exent (-1,141,933 km²) for more: osi-saf.eumetsat.int/sea-ice-index

Look at the Barents Sea! Relative to the 1981-2010 climate reference period, there is unusually little sea ice for this time of year. In fact, the Barents Sea ice extent has reached record-low levels in six of the past 12 months (Aug-Dec and June), indicating later freeze-up and earlier melt.
On Saturday,research vessel Polarstern will head to HAUSGARTEN,a long-term Arctic observatory in the Fram Strait. Since 1999,it has recorded ecological changes in the water column and on the seafloor, providing key insights into climate impacts on polar marine ecosystems. www.awi.de/en/about-us/...

In 1999, the Alfred Wegener Institute launched an ambitious project: the HAUSGARTEN observatory in the Fram Strait between northeast Greenland and Svalbard. Spanning ice-covered waters and extending t...

🟦🟥 It's #ShowYourStripes day! Tell the world that you care about climate change. You can explore the warming signal for your own city and create and share Ed Hawkins' climate stripes using the C3S ERA Explorer: era-explorer.climate.copernicus.eu
#ShowYourStripes I've updated my Svalbard collage of beautiful Hjortfjellet in Longyearbyen with the warming stripes from Svalbard - showyourstripes.info Svalbard is among the fastest-warming places on Earth!
As is the annual tradition, we hope many of you will take the opportunity to use the Climate Stripes this week to start important conversations about the risks from, and solutions to, climate change. Officially, #ShowYourStripes for 2026 is on Sat 20th June. www.ShowYourStripes.info
Trying to refreeze Arctic sea ice by pumping ocean water onto its surface is infeasible and a distraction from emissions cuts, but it signals how desperate we are because we’re simply not decarbonizing fast enough (or at all).

In this week’s newsletter: The melting of the Arctic’s summer sea ice is the most visible upshot of the climate crisis. Refreezing it might be a long shot – but do drastic times call for drastic measu...

In May 2026, the #SeaIce global extent was 6.9% below 1991-2020 mean. Since the beginning of records (1978): - #Arctic, 4th lowest monthly mean, with 4.4% less extent (-575,397km²) - #Antarctic, 7th lowest monthly mean, with 8.7% less exent (-923,279km²) for more: osi-saf.eumetsat.int/sea-ice-index
I’m probably late to the party, but Met Norway now has regional #SeaIce data/graphic for all the regions of the #Arctic (and Antarctic). The regions don’t exactly match the NSIDC regions, but in the ball park. Tusen takk! @signeaaboe.bsky.social @zacklabe.com @seaice.de cryo.met.no/en/sea-ice-i...

Spiralling global temperatures (1850-2026) It is exactly 10 years since I first put this animated graphic of changes in global temperature online. #ClimateSpiral It instantly went viral. People watched it over and over again. It still offers the power to shock a decade on.
Er nasjonalt månedskort en god idé? En ny utredning er skeptisk, men etter vår mening undervurderer den kraftig de positive effektene av en slik frihetsreform.
The ice loss of the Greenland Ice Sheet is hard to grasp! This is what the 30 million tonnes of ice that Greenland loses every hour looks like, if it were positioned next to the Eiffel tower before melting:
💧Precipitation in Europe in 2025 showed strong contrasts: northwestern, central & eastern Europe were much drier than average, while southwestern & parts of northeastern Europe were wetter than average. 2025 ranked among the 10 driest in 47 years for northwestern & central Europe. More details ⬇️
Over our 40-year history, Meteosat – Europe’s geostationary weather satellite series – have been the go-to source for imagery of the entire Earth disc over Europe & Africa. One of our first responsibilities was to take ownership of Meteosat-1 and -2 from @esa.int on 1 January 1987. 🧵1/3 #EUMETSAT40
