Šujan et al investigate the Early Pleistocene sediments in Lithuania, and conclude that the first advance of the Fennoscandian Ice Sheet there happened during the Elsterian Glaciation (MIS 12). A unit that was previously interpreted as an earlier advance is now interpreted as a debris flow.

The Fork in the Road
We are at a Shakespearean "tide in the affairs of men." The technology is here, the economics finally add up, and the urgency is staring us in the face. Will we choose the path of collapse, or are we smart enough to take the roadmap to a sustainable century? Watch to find out how we can turn the "catastrophic" into the "profitable."#TippingPoints

You launch your #Argo float to do one job... 2 and a half years later it pops up with with a stunning data set. It not ALL bad news ... just mostly. :(
Still ! BONUS ! brilliant engineering and deductions.
<quote>
Drifting in remote and wild seas for two-and-a-half years, the float spent about nine months beneath the massive Denman and Shackleton ice shelves. It survived to send back new data from parts of the ocean that are usually difficult to sample.
</quote>Also the paper which outlines how they reconstructed the route of the intrepid float, and methodology etal.

Coming back to this at #NCKF25 where my former boss (+IPCC lead author) Jens Hesselbjerg Christensen is looking at #Eemian #SeaLevelRise
Not quite as catastrophic as the MWP1a but still large. I wonder if this has been updated recently at all?
https://fediscience.org/@Ruth_Mottram/115304238980577506
Ruth_Mottram - This plot on wikipedia was made by @RARohde based on data published in late 90s and early 00s. Wondering if this has been updated or if there is new understanding on any of these palaeo records?#Palaeoclimate #SeaLevelRise #IceSheets
Maybe @DrEvanGowan has thoughts? Anyone else? -
Next week our ECR group are starting a #MachineLearning sprint to speed up the development of our new #IceSheet surface mass budget emulation models.
I'm looking for hints, ideas tips and inspiration to help smooth and accelerate the process.
If you're used to working in #Sprint mode, what in your opinion makes it work or otherwise hinders it?
What can I as supervisor do to make it run better?
And how should we celebrate it's conclusion?Also, should me do an #AMA on the process?

The #USA Buried #NuclearWaste Abroad. #ClimateChange Could Unearth It
A new report says melting ice sheets and rising seas could disturb waste from US #nuclear projects in #Greenland and the #MarshallIslands
by Anita Hofschneider
Science
Mar 2, 2024 8:00 AM"Ariana Tibon was in college at the University of Hawaii in 2017 when she saw the photo online: a black-and-white picture of a man holding a baby. The caption said: 'Nelson Anjain getting his baby monitored on March 2, 1954, by an AEC RadSafe team member on Rongelap two days after ʻBravo.’
"Tibon had never seen the man before. But she recognized the name as her great-grandfather’s. At the time, he was living on Rongelap in the Marshall Islands when the US conducted #CastleBravo, the largest of 67 nuclear weapon tests there during the Cold War. The tests displaced and sickened #Indigenous people, #poisoned fish, upended #TraditionalFood practices, and caused #cancers and other negative health repercussions that continue to reverberate today.
"A federal report by the Government Accountability Office published last month examines what’s left of that nuclear contamination, not only in the Pacific but also in Greenland and #Spain. The authors conclude that #ClimateChange could disturb nuclear waste left in Greenland and the Marshall Islands. '#RisingSeaLevels could spread contamination in RMI, and conflicting risk assessments cause residents to distrust radiological information from the US Department of Energy,' the report says.
"In Greenland, #ChemicalPollution and #radioactive liquid are frozen in #IceSheets, left over from a #NuclearPowerPlant on a #USMilitary research base where scientists studied the potential to install nuclear missiles. The report didn’t specify how or where nuclear contamination could migrate in the Pacific or Greenland, or what if any health risks that might pose to people living nearby. However, the authors did note that in Greenland, frozen waste could be exposed by 2100.
"'The possibility to influence the environment is there, which could further affect the food chain and further affect the people living in the area as well,' said Hjalmar Dahl, president of #InuitCircumpolarCouncil Greenland. The country is about 90 percent #Inuit. “I think it is important that the Greenland and US governments have to communicate on this worrying issue and prepare what to do about it.'"

After #IMBIE, now #GLAMBIE - the #glaciers mass balance intercomparison - their contribution to #SeaLevelRise is currently bigger than the #IceSheets but by the end of this century many of them will be gone.
We will miss them 😢
-
The very talented Ines Otosaka is presenting the #IMBIE project that estimates the mass change of #iceSheets and contribution to #SeaLevelRise
#ESSI
The 3rd IMBIE is in the pipeline now and it's going to be enormous...#Greenland has contributed about 15mm since 1972, #antarctica a bit less, where there is higher uncertainty but most of it is from #WAIS

Evidence of Earth’s Oldest #Glaciers Found in South Africa

"Drawing on evidence from some of the oldest undisturbed rocks on #Earth, the study authors said they see evidence for #IceSheets during the #planet’s ancient #Archaean eon similar to those found today in #mountain ranges across the world. It is the oldest evidence of glaciers ever #discovered"

Off to #IUGG this morning to talk #IceSheets #CMIP6 #CMIP7 and #ISMIP7, but stopping by @rahmstorf 's talk on #AMOC #TippingPoints first.
Give me a shout if you're at #IUGG23 this week and want to meet up!

"#IceSheets are littered with millions of tiny hairline cracks that are forced open by the #meltwater from the rivers and streams that intercept them.
As the water pours in, it damages the ice sheet structure and releases its latent heat. The ice fabric warms and softens and, hence, flows and #melts faster, just like warmed-up candle wax."

Not sure how to say this delicately, but...
...since starting @ClimateMigration yesterday, the vast majority of Followers are from outside the US. Understand this is not a fun subject, but the disparity in attention to this topic is pretty striking.

More generally on #IceSheets - rather nice and new study published by @DrEvanGowan on #iceSheetModels
The impact of spatially varying ice sheet basal conditions on sliding at glacial time scales: it turns out the input of meltwater at the bed is more important that particular sliding styles

Fantastic + beautifully illustrated article in Danish Newspaper #InformationDK about the project my #DMIdk colleague Steffen M Olsen has pioneered over the last 15 years in #Qaanaaq NW #Greenland.
And now we're adding #glaciers + #IceSheets as part of #NCKF work.
In Danish but try DeepL to translate.
This should be a gift link! 🎁 -
