Earth Observation 🛰️| Sea Ice ❄️| Digital Twins 🌍 Research background in sea ice remote sensing and in-situ observations of atmosphere-sea ice-ocean interactions in the Arctic. Now at DLR as program manager for digital twins in EO (DestinE and ESA DTE).

🌍🌐 The 3rd ECMWF Destination Earth (DestinE) Annual Meeting in Bologna has come to a close. Thank you to all participants that came together from all over Europe. This event once again showcased the great spirit of European collaboration, advancing this ambitious initiative of the EU. #DestinE

Awful. More horrible science news "The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) learned yesterday that the Department of Defense (DoD) will stop processing & delivering the Special Sensor Microwave Imager/Sounder (SSMIS) data no later than 30 June 2025."

Screenshot from NSIDC that says: "Dear Colleague:

The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) learned yesterday that the Department of Defense (DoD) will stop processing and delivering the Special Sensor Microwave Imager/Sounder (SSMIS) data no later than 30 June 2025. The SSMIS data are used as input for the following NSIDC DAAC-produced data sets, which will therefore stop processing no later than 30 June 2025:"

Potentially no updates to sea ice indices coming from the US for a while... this is horribly damaging to global climate science. Yes, there are EU and Japanese alternatives to some of these, but multi-dataset inter-comparisons are a critical part of assessing reliability and confidence in the data.

This is horrible. I don't even know what to say. Some of our most key polar data. "As a result, the level of services for affected products below will be reduced to Basic—meaning they will remain accessible but may not be actively maintained, updated, or fully supported." nsidc.org/data/user-re...

Effective May 5, 2025, NOAA’s National Centers for Environmental Information (NCEI) will decommission its snow and ice data products from the Coasts, Oceans, and Geophysics Science Division (COGS). As a result, the level of services for affected products below will be reduced to Basic—meaning they will remain accessible but may not be actively maintained, updated, or fully supported. This includes Sea Ice Index, Snow Data Assimilation System (SNODAS) Data Products, Glacier Photograph Collection, U.S. National Ice Center Arctic Sea Ice Charts and Climatologies in Gridded Format Gridded Monthly Sea Ice Extent and Concentration, 1850 Onward World Glacier Inventory. If you rely on these products in your work, research, education, or planning, we invite you to share your story at nsidc@nsidc.org. Your input can help us demonstrate the importance of these data sets and advocate for future support.

Go go go! 11000 Wissenschaftler:innen aus DE, sehr stark! Vielleicht an der Zeit für @taz.de, @derfreitag.bsky.social, @zeit.de, @deutschlandfunk.de.web.brid.gy und co. das Ganze mal aufzugreifen.

"What ever it takes" sollte sich unbedingt auch auf den Ausstieg aus der Nutzung fossiler Energieträger beziehen. Seit 1991 haben wir für über 1800 Mrd. € Erdöl, Erdgas und Kohle importiert und uns mit den Zahlungen überhaupt erst in die heutige dramatische Lage gebracht.

Astonishing sea ice dynamics north of Greenland at the moment. One of the few occasions (2003, 2011, 2013 and 2018 in the last 25 yrs) of large polynyas opening up in that region during winter. One to watch!

Lars Kaleschke@seaice.de · 2y ago

Well, what did I say? Now there is again open water north of #Greenland where the thickest sea ice of the #Arctic used to be. An almost 500 km long lead opened up over the last few days. This is similar to the event in February/March 2018, which resulted in a series of scientific publications.

Alice Weidel nennt Universitäten "queer-woke Kaderschmieden" und sagt: "Wir schließen alle Gender Studies und schmeißen alle diese Professoren raus". Die Naturwissenschafts-Community muss sich hier klar auf die Seite der Geistes- & Sozialwissenschaft stellen. Das ist ein Angriff auf alle. (Thread)

Great and scary visualization! While unfortunately well on track to plow through the 1.5°C target, average global warming sits around 1.2°C. And we already see wildfires in January, flood-inducing rain around the world, droughts…well below 1.5 or even 2°C!

NEW: 2024 has just been confirmed as the warmest year on record, and the first to breach the 1.5C threshold. We used a ridgeline (Joy Division inspired) chart to visualise daily temperature anomalies since 1940. 2024 clearly stands out with 100% of its days above 1.3C and 75% above 1.5C.

Ridgeline chart showing the distribution of global daily air temperature differences from the pre-industrial reference period (1850-1900), for every year between 1940 and 2024. Each individual year resembles a hill, shaded in a darker shade of red and further to the right for warmer years. The trend is clearly towards warmer years, with 2024 standing out as first year above 1.5C.
