🚨Fortuitous new paper drop right in the middle of #EGU23! In it @bjsimonsen, @anja_ruti and I look at a new way of observing density and roughness across Greenland using @esa_cryosat and #SARAL. Big thanks to @ProtectSlr @VILLUMFONDEN and #GEUS doi.org/10.1029/2022GL…

Sea level rise (#SLR: 📈=🌊+🧊💧) from 🇬🇱Greenland Since 1990 (IPCC FAR): ~14.8 mm (-5353 Gt) 2023 → today: 21 Gt Next 7 days (2023-04-25 →️2023-05-01)📈: 0.02 ±0.0 mm (-6.5 ±1.4 Gt) doi.org/10.5194/essd-1… doi.org/10.22008/FK2/O… github.com/GEUS-Glaciolog…

Excited to present our new @Nature paper! Our findings show that an ice sheet retreated at up to 600 m/day at the end of the last Ice Age. Read for free here: rdcu.be/c9eZ4 @frazer_christie @sasha_montelli @JEGlaciers @NCLPhysGeog 1/6

We are delighted to announce that Dorthe Dahl-Jensen has been awarded the Seligman Crystal for the year 2022. For more details please visit igsoc.org/about/awards/s…

🎧: In Ep 2 of our new climate podcast Fear & Wonder, our hosts @michaelbgreen + @joellegergis discuss how climate scientists measure sea level rise. Guests: Guðfinna "Tolly" Aðalgeirsdóttir (@uni_iceland) + @mpclimate (@metoffice + @BristolUni) Listen: theconversation.com/fear-and-wonde…

Warmly recommended....

Safety first! Back in windy Iceland to practice glacier rescue techniques before the field season on the Greenland Ice Sheet begins

We welcome Anna Puggarrd, our newest Ph.D. student who will be working on remote sensing of the surface mass balance of the Greenland ice sheet. The Ph.D. is a collaboration between DMI (@ruth_mottram), GEUS (Anne Solgaard), and @DTUcryo (@LSandbergS and @bjsimonsen).

It is with deep sorrow we report the death of Emeritus Fellow, Professor David Vaughan.  He was suffering from cancer and passed away peacefully at home on Thursday 9 February 2023. bas.ac.uk/media-post/pro…

New shoot on sea level rise in Denmark. Clear message from @KK_Kjeldsen #dkvid #geus

THREAD: I’m going to try this thread to clearly state my perspective on electric vehicles, car dependency and better cities, to those who frequently ask me, including media, elected leaders and many others. Here goes. Please share if you think it helps. 🧵#EVS

Our Geocenter-project published an article in @GeusBulletin reviewing AR6 projections for Denmark. With the most relevant planning targets having increased c. 50 cm in 20 yrs, there is a clear need for continuing to deliver up-to-date numbers ! geusbulletin.org/index.php/geus…

And a new season begins…

The highest melt event of this 2021-2022 melt season over the Greenland ice sheet occurred 2 days ago while we are the beginning of the fall. This resulted from advection of a very warm and wet air mass with liquid water clouds boosting the melt thanks to infrared radiation

Congratulations to our postdoc @kirk_scanlan on his successful @VILLUMFONDEN #VillumExperiment proposal! Can't wait to see where your research leads! #dkforsk

“it was really a crazy day last Thursday in terms of temperature, 7.5 C daily average, warmest melt day of the year at QAS_L” @Maurice_vTgln @PromiceGL
