A very, very good day in the Cairngorms.

⬇️ LAUNCHED TODAY ⬇️ State of the Cryosphere Report 2025 Over 50 leading cryosphere scientists warn that current climate commitments, leading the world to well over 2°C, spell disaster for billions from global ice loss – but that damage can still be prevented. Read here: iccinet.org/statecryo25/

Fantastic to see our colleagues Professor Bethan Davies @iceybethan.bsky.social and Dr Owen King contributing to UNESCO & WMO’s new volume Glaciers and Ice Sheets in a Warming World: Impacts and Outcomes! www.ncl.ac.uk/press/articl...

Just as an aside: tell EVERYONE you know about this. www.theguardian.com/environment/...

I'm delighted to inform you that teens are still playing The Game. Also, since it's likely been a while, you just lost The Game.

Some amazing information about Andrzej Bargiels O2less ski descent of Everest here. Also talks of big changes in his 13 years on the mountain and increasing risk in a warmer world. Yikes. explorersweb.com/andrzej-barg...

Fab week in Innsbruck featuring some light International Mountain Conferencing and a bit more ice creaming and exploring.

My tallest sunflower got too big for its very tiny boots. 6ft 4 me for scale.

The #Glacier Loss Day is reached in Switzerland! From now on all melt that occurs on glaciers until October is unsustainable. This tipping point has only been reached so early in the record-shattering year 2022. Expect big ice loss due to the prolonged melt season and feedback effects

A very pretty satellite image taken over the South Patagonian Icefield in 1973. Apparently I am not allowed to set this as my desktop background for university IT reasons, so here you go Bluesky.

So NERC have quietly announced this afternoon that they're delaying/cancelling/suspending, whatever 'not launched at this time' means, their 2025 Independent Research Fellowship round. After announcing it 34 days ago. Flip-flopping like this is really detrimental to early career researchers.

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: theconversation.com/frozen-thawe...

Is it hot right now in the UK? New interactive website allowing anyone to explore live temperatures hour-by-hour across the UK, and whether they are cool, warm or hot relative to normal. istheukhotrightnow.com Built by @roostweather.bsky.social.

I have never felt such guilt whilst snacking.

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....

We estimate the average Alaska lake-terminating glacier has 9 km of lake expansion potential and will remain in contact with its proglacial lake for the next 74 years. This makes process understanding of glacier-lake interactions important for projecting glacier response to #climatechange

Elevation change maps to compare with Mauri's snowcover obs. Thinning throughout the elevation range of the ice cap now, although it has been an unhappy ice cap for a while. Moraines flanking the recently formed ice marginal lakes certainly not stable on the eastern side of the ice cap either. ❄️🧪

Quelcaya Ice Cap, Peru snowline in 2024 was 5600 m, leaving less than 25% snowcovered. The retreat since 2013 of several marginal lakes is evident in the Landsat comparison. The limited snowcover persisted from Augutst-October 2024 Sentinel images #glaciology.

To celebrate this first ever World Day of the Glacier, and to highlight the role of climate change in shrinking the glaciers of the Andes, we are delighted to produce a first Deplete and Retreat Policy Brief on the future of the Andean water towers. www.antarcticglaciers.org/2025/03/poli...

I'm at UNESCO tomorrow. On a panel for about glacier preservation. Isn't that how everyone celebrates their birthday? You can witness the rare event of me wearing a suit by registering here: unesco-org.zoom.us/webinar/regi...

Another chapter in the enshittification of US Govt websites: USGS Earth Explorer no longer has a satellite data basemap (which for a geospatial search tool is kinda useful) and also outside of the US, you can't even zoom very far. How is this saving money or making things more efficient? 🧪⚒️

The Glacier Mass Balance Intercomparison Exercise is out! Herculean effort bringing together >200 estimates of glacier loss outside the ice sheets. Bottom line is 273 gigatonnes per year of ice loss since the year 2000! 😲 Open-access article: doi.org/10.1038/s415... 🥼❄️ @natureportfolio.nature.com

Recharging before another relentless week of doing exactly this.

As it is strictly forbidden to make a presentation about glaciers without including any nice pictures of glaciers, here's a nice picture of Upsala Glacier from April 1973 which will be included in the presentation I'm making about glaciers. It's retreated 11.5 km since then.

I did not have skiing 10 miles from Edinburgh city centre on my bingo card for the year! A grand day out with @lawrenceeagle.bsky.social in the Pentland Hills.
