Work by Barndon & Lima presented at the #EGU2026 🌍🧊 We simulated glacier change over the last 130,000 years across mountain ranges worldwide. The preprint is already available here: zenodo.org/records/1819... #Glaciology #Cryosphere #MountainGlaciers #Paleoglacier #GlacierModelling

How have we been building and validating mountain palaeoglacier models? At #EGU26 I presented: Validation practices in mountain palaeoglacier modelling 🔗 meetingorganizer.copernicus.org/EGU26/EGU26-... #EGU26 #glaciers #paleoclimate #modelling #OpenScience

We thank of course the paleoglacier community who provided their data in open-access format! Very proud of this collaborative effort with @berylliumben.bsky.social @iestynbarr.bsky.social @annalchughes.bsky.social #HelenDulfer #MartinMargold

A key takeaway: Global knowledge is uneven. 🗺️Some regions are well studied, while others remain major blind spots. This is a roadmap for future research across disciplines. ❄️ Cryosphere 🌦️ Climate 🌱 Ecosystems Our #GLACIMONTIS is openly available here: zenodo.org/records/1560... #OpenScience

MANY mountains had glaciers but they didn’t expand everywhere equally. ⛰️ "Local LGMs" are evident everywhere as mountains differed in when glaciers had maximum extent. And some mountain ranges were extensively glaciated, few remained ice-free, and several regions are still poorly constrained.

It wasn’t easy to get the data.... Old maps, outdated emails, unresponsive authors are challenges for global compilations. And many papers without open-access data☹

Our geodatabase is called #GLACIMONTIS! 🩵 What’s new here: • Global synthesis 🌎 🌍🌏 • Standardised geospatial database 🌐 • Direct link to original studies 🧾 • Identification of major data gaps 🗺️ 🌍 15,000+ glacier reconstructions ⛰️ 271 mountain ranges 📚 209 studies

We just published a global synthesis of mountain glacier extent during the last ice age! #LGM www.nature.com/articles/s41... @natureportfolio.nature.com Led by marvellous ECR Augusto Lima @ac-lima.bsky.social mountainsinmotion.w.uib.no @mohnfoundation.bsky.social @bjerknes.uib.no #UIB-BIO 🧵👇
