@Doemgaard explains his lates results on East Antarctic stability to DR1. Watch it tonight on prime time after the 9 o'clock news! dr.dk/drtv/kanal/dr1_20875 This work is part of the AIR project funded by @VILLUMFONDEN Read the whole story here: nature.com/articles/s41467-0…
Sitting in the historical setting of the Royal Danish Geographical Society, Mads Dømgaard is explaining his latest results to Radio Denmark (DR1). The project has made the longest reconstruction of aerial images in Antarctica to date, and show that part of East Antarctica has been extremely stable in the last 85 years. However, bigining signs of instability are starting to show.

Have a look at our new research! A huge project led by @Doemgaard shows the longest historical reconstruction of glaciers in Antarctica. This part of East Antarctica has been remarkably stable during the last 85 years, but signs of weaknesses are showing.. nature.com/articles/s41467-0…

Greenland’s ice shelves hold back sea level rise. There are just 5 left.

Greenland’s floating ice platforms — which hold back trillions of tons of ice that could cause sea level rise — are in stark decline, according to a new study.

We have a new and important paper out on the state of the last ice shelves in Greenland. They have recently lost more than a third of their volume, and as a result sea-level rise will accelerate. Read this great 🧵and here: ign.ku.dk/english/news/2023/… Paper: nature.com/articles/s41467-0…

The beginning of the end for Greenland’s last remaining ice shelves

A new study just published in Nature Communications, shows that Greenland’s last stable ice shelves have started to thin and disintegrate, accelerating the global sea-level rise.

New work led by Abbas Khan @DTUtweet With measurements in the field, from satellite, and with modelling we show the importance of getting the basal conditions right for NEGIS in Greenland. Collapse is inevitable - giving up to 15 mm sea-level rise by 2100 nature.com/articles/s41586-0…

Late glacial and Holocene glaciation history of North and Northeast Greenland

Northeast Greenland is the place where the Greenland Ice Sheet (GrIS) experienced the largest areal changes since the Last Glacial Maximum. However, the age constraints of the last deglaciation are...

It's been years in the making, and today we're releasing our new Greenland geothermal database & map. There's 33 authors from 8 countries really hoping it advances Greenland science! 👍 News: eng.geus.dk/about/news/news-… Article: doi.org/10.5194/essd-14-2209… Data: doi.org/10.22008/FK2/F9P03L

Mapping geothermal heat in Greenland shows unexpected coolness

In our understanding of global geothermal heat flow, Greenland and the surrounding ocean floor has effectively been a blind spot. Now, scientist have dug up all available and somewhat unavailable...

@G_Luetzenburg mapped a 130m long coastal cliff, with an accuracy of 10cm. That is pretty impressive for a tiny gadget that you might already have in your pocket. Possibilities 🤯

Our new study links bedrock uplift & ice discharge at Jakobshavn Isbræ. We find the ice discharge response lags the uplift response by 0.9 yrs. So, knowing today's uplift can predict tomorrow's ice discharge! 🛰️ blog: williamcolgan.net/blog/?p=67… article: doi.org/10.1029/2021GL094252

Our new research shows the island’s largest glaciers are losing ice faster than previously thought.

Our new @NatureComms study shows three Greenland glaciers contributed 8mm to *global* sea-level rise since 1900. But *local* sea level has fallen at these glaciers (up to 500mm!) due to weakening local gravity. Article: nature.com/articles/s41467-0… News: eng.geus.dk/about/news/news-…
