The hammer fell on NOAA/NWS this afternoon. 😭💔 There were no exceptions. All probationary employees.

Very excited to learn that the 2026 Ocean Sciences meeting in Glasgow will have an official tartan!

Last week we were in #Bremen with media representatives and experts from our partner organisations to take an exclusive look at our Meteosat Third Generation – Sounder 1 spacecraft 🤩Take a look at our gallery here: flic.kr/s/aHBqjC3Lk1

Five years ago. This lead was a relief. It brought us closer to Polarstern, in the middle of the #Arctic #Ocean. 🌊

Looking for a polar bear postdoc? Here's a really neat opportunity on a new project with a great group. www.yorku.ca/vpepc/facult...

I’m just so angry. We are nonstop receiving these intentionally terrorizing emails at all hours of the day and week (or waiting for them to arrive…).

Fight against the normalization!

So much is at stake when Germany goes to the polls tomorrow. My take on Friedrich Merz and a huge mistake he made during the campaign. While Germany can't be seen as that borderline-boring bastion of stability anymore, the centre might get its act together after all, ironically thanks to JD Vance. 👇

If you're looking for an alternative to PIOMAS when it comes to sea ice thickness, I recommend this dataset by my colleagues at the Nansen Center!

In 1931 Mussolini imposed to all academics to pledge allegiance to the fascist regime -- or be fired. Just *12* out of ~1200 academics chose not to in the whole country. Here are the names of those brave few who chose to forfeit their careers.

📡❗️New instrument alert! We tested our new L-Band #radiometer "Ariel" which we will use in the #Arctic this summer. Observations of the surface at this frequency contain information about, e.g., sea ice thickness or soil moisture, and maybe even ducks?! ➡️ We will let you know!

Happy Birthday Neumayer and welcome @awi.de! ❄️🧊🌊🧪🌍🛰️ #Antarctic #Arctic #Climate

Shocking. It is hard to overestimate the importance of all the wonderful research and observations from NOAA @climate.noaa.gov and other US-based agencies. Huge support to Zack and others who are affected.

Polarstern expedition planning workshop Polarstern operations “Antarctica InSync” and “Arctic Pulse". The workshop will take place from 24 – 25 April 2025 at “Haus der Wissenschaft” in Bremen. 🌊 survey.awi.de/index.php/19...

The Northeast Greenland Ice Stream (NEGIS) is losing ice fast—accounting for some 12% of the ice sheet’s mass loss. #AWI researchers used radar surveys to examine its structure. As #NEGIS slides on mud, ice loss may accelerate. www.science.org/content/arti...

Monday ice update - #Arctic sea ice extent is currently the *lowest* on record (JAXA data) • about 570,000 km² below the 2010s mean • about 1,140,000 km² below the 2000s mean • about 1,670,000 km² below the 1990s mean • about 2,040,000 km² below the 1980s mean Plots: zacklabe.com/arctic-sea-i... 🧪

Was derzeit in den USA passiert, ist ein Albtraum. Die besten Klimaforscher werden gefeuert und zum Schweigen gebracht. Dies wird die Probleme der Zukunft nicht lösen.

I really cannot believe my childhood career dream might end like this. Feeling so small and lost.

Die Steuerversprechen von Union, AfD und FDP für Spitzenverdiener sind angesichts der verteidigungspolitischen Notwendigkeiten und dem Zustand der Infrastruktur schlicht nicht finanzierbar. (Berechnung @mbloemer.bsky.social @apeichl.bsky.social et al, Grafik @zeit.de) www.zeit.de/wirtschaft/2...

Another independent confirmation of the new global temperature record. 🌍🌊🧪

The extent of sea ice globally is now at an absolute record low level for the entire satellite-era. [Graphics: zacklabe.com/global-sea-i.... Note: the poles are affected by very different Earth system processes/seasonality. I am using 5-day running mean data.]

Meereisphysiker:innen des #AWI haben erstmals eine Karte der Plättcheneis-Verteilung in der Atkabucht in der #Antarktis erstellt. Diese soll als Ausgangspunkt dienen, um das Zusammenspiel von Ozean, Schelfeis und #Meereis besser zu verstehen. Zu unserer News: www.meereisportal.de/newsliste/de...

Since 1984, CEOS (Committee on Earth Observation Satellites) coordinates civilian Earth observation missions globally. NASA & NOAA skipping their next meeting raises serious concerns for future collaboration and data sharing across space agencies. #EarthObservation #SpacePolicy #CEOS

Gemeinsam KANTE ZEIGEN. Für das #DemokraTEAM! 💪 Vor der Bundestagswahl setzen wir uns für eine gerechte, solidarische & demokratische Gesellschaft ein. Wir rufen dazu auf, am 23.02. wählen zu gehen & gegen Ausgrenzung, Spaltung & Hass einzustehen. Dafür steht auch unser neues Banner! 🤩 #Werder

Five years ago in the middle of the #Arctic #Ocean.

“The Musk approach is, ‘Hey, I'll break it and if somebody says afterwards you shouldn't have broken that, I'll say, oops,’” Rosenberg said. “Once they destroy the agencies, they're not going to be able to put them back together again, no matter what a judge says.”

Hello world! We'll be sharing insights, updates and visuals from our research about the fascinating world of remote sensing of polar regions right here in this place of Rayleigh scattering (aka Bluesky). Sea ice lovers, satellite enthusiasts, cloud admirers, snow fans, science nerds: let us connect!

Monday ice update - #Arctic sea ice extent is currently the *lowest* on record (JAXA data) • about 780,000 km² below the 2010s mean • about 1,450,000 km² below the 2000s mean • about 2,010,000 km² below the 1990s mean • about 2,370,000 km² below the 1980s mean Plots: zacklabe.com/arctic-sea-i... 🧪

This is truly astonishing, especially considering that the last few years represent the so-called new #Arctic. 🌊⚒️🧪🥼❄️

The full stop of the increasing winter sea-ice extent in the Arctic has now lasted for two weeks... 🌊⚒️🧪🥼❄️

A look at how #Arctic sea ice responded to the recent southerly flow of excessive heat and moisture. This same event resulted in the sudden anomalous temperature spike around the North Pole... Data is from the 3-km AWI SIC-LEADS algorithm using AMSR2 satellite.

The magnitude of the current size of the #Arctic sea ice extent anomaly is unheard of in the satellite-era record for the deep winter season months. Data from nsidc.org/data/seaice_...

Eins von diesen Jahren passt nicht zu den anderen... Ihr dürft mitraten!

Strategisch gegen Rechts heißt, progressive Parteien wählen, die realistische Chancen haben, in den Bundestag einzuziehen: #SPD, #Grüne und #Linke. Je mehr demokratische Abgeordnete in den Bundestag kommen, desto weniger Sitze für Faschisten (und deren Steigbügelhalter). #HerzStattMerz #noafd #BTW25

It's always great to visit Helsinki-one of my favorite cities in the world. This time, I caught a glimpse of sea ice, which we’ll be modeling in the @terradt.bsky.social project (by the way, we're hiring!). The project kicked off in Helsinki this week.

Die aktuelle Erwärmung der Arktis ist extrem. Eisausdehnung auf Rekordminimum und unglaublich hohe Temperaturen. Rund 20 Grad wärmer als normal! Über der gesamten Fläche nördlich von 80 Grad. 😳 Quelle: DMI

#NieWiederIstJetzt oder #NieWiederWarGestern hat man langsam das Gefühl?! Steh auf zur Kundgebung in #Bremen um 16 Uhr auf dem Marktplatz oder ab 15 Uhr in der Innenstadt ;) (s.u. von @Omasgegenrechts Bremen) und bring jemanden mit!

What’s your vision for the next International Polar Year? 🤔 Shape the next decade of polar research! ❄️🌍 #PECWS2025 invites early career researchers to share their priorities. 👉 Submit your input by 23 Feb 2025 www.pecws.org/input 📢 Attending or not, your voice matters!

The extreme winter warming event continues in the northernmost portions of the #Arctic. This is related to a temporary surge of heat and moisture that was transported northward and is related to the orientation of the large-scale atmospheric circulation. Graph from zacklabe.com/arctic-tempe...

Arctic sea ice reached its lowest monthly extent for January, at 6% below average. Antarctic sea ice extent was 5% below average and thus relatively close to average compared to other recent years. Dive into analysis of the #C3S Climate Bulletins: bit.ly/4aQUPM2
