GEEDiT helping understand how emperor penguins will respond to climate change!

Really cool study by @geogeordie.bsky.social out now in Antarctic Science 🐧🐧🐧

Awesome stuff. Let me know if you run into anything (hoping it's fairly bombproof though!). Pints at EGU of you're going?

New year, new data for GEEClimT and all your climate reanalysis needs!

Now giving easy access to:
- ERA5 Hourly (1940-present, 292 variables!)
- New *Palaeoclimate* datasets (back to 800k BP!)
- 27 other climate and ocean datasets (>400Tb of data!)

Extensive fluvial surfaces at the East Antarctic margin have modulated ice-sheet evolution - Nature Geoscience Extensive flat surfaces observed beneath the East Antarctic Ice Sheet margin were formed by fluvial erosion and have modulated the ice-sheet response to climate change, according to an analysis of rad...

Great work by our colleagues Stewart Jamieson and Guy Paxman: "We have been using satellite data to map an ancient river landscape beneath the East Antarctic Ice Sheet:. The landscape has been frozen in time for up to 34 million years." βš’οΈπŸ§ͺ

Frozen, thawed: how Arendelle’s glacier would fare under modern climate change A glaciologist investigates a Disney classic.

Inspired by many, many viewings with my kids, I wrote something for @uk.theconversation.com that imagines how the Arendelle glacier in Disney's Frozen might look after 200 years of climate change:

Schematic illustrating estimation of frontal ablation on lake-terminating glaciers

Excited that Noah Caldwell's work is officially out in @igsoc.bsky.social Journal of Glaciology! Noah used satellite remote sensing to estimate how much ice is being lost to iceberg calving and subaqueous melt on 55 Alaska lake-terminating glaciers. Read more: doi.org/10.1017/jog....

Unfortunately not at EGU as planned this year, but Steve Brough is stepping in for me this afternoon to tell you how many glaciers globally have disappeared or fragmented since 2000. CW: it's a *lot*

Penny in Iceland last week. She is taking a selfie on SΓ³lheimajΓΆkull, wearing a helmet, sunglasses, and gear for being on a glacier and learning some rescue training. It is very sunny and warm, so smiles all round!

I should probably re-introduce myself here to new and old connections…

Well worth a read for all glacios, and that Karl Schimper (amongst others) should be much better known!

Increased crevassing across accelerating Greenland Ice Sheet margins - Nature Geoscience Greenland-wide observations of crevasse volume and distribution suggest substantial increases in crevassing between 2016 and 2021 at marine-terminating sectors with accelerating ice flow.

Our new paper is out in Nature Geoscience! In an ice-sheet-wide 3-D inventory of crevasses in 2016 and 2021, we find that crevasses are growing in response to ice acceleration on short timescales. @durham-university.bsky.social @byrdpolar.bsky.social @leverhulme.bsky.social
