🏔️❄️New paper: “Multi-temporal DEMs used to quantify the geomorphological impact of a late 20th century glacier re-advance at Schwarzberggletscher, Switzerland”. www.sciencedirect.com/science/arti... #glaciers #climatechange #sfm #geomorphology

Left high and dry, this former glacial meltwater channel was carved into the Sidlaw Hills just north of Dundee by the last ice sheet to occupy this region ~20,000 years ago. It’s one of several that i’ve been mapping with students & colleagues over the last couple of years.

Met Office stats confirm summer 2025 is officially the warmest summer on record for the UK. The UK’s mean temp of 16.10°C surpasses the previous record of  15.76°C and pushes the summer of 1976 out of the top 5 warmest summers. www.metoffice.gov.uk/about-us/new...

Northwest Scotland is hard to beat

The extent of the deposit from the Birch Glacier collapse over Blatten as seen by newly available high-resolution satellite imagery collected by Maxar! 🛰️ Processed by @wxnb.bsky.social

First heli inspection of what remains of Blatten yesterday evening... 🚁😱🌊 SHOCKING! Few buildings left are flooded Little debris flow run through the deposit Look at the height reached on the counterslope! 😮 🎥 Pomona

On 28 May 2025, the Birch Glacier in Switzerland catastrophically failed, generating a massive landslide that has partially buried Blatten. So what happens next? eos.org/thelandslide...

Maybe >~100 🏠 buried by the glacier+rockfall collapse in Blatten (polygon quickly drawn from 📷 pomona.ch). Upstream part of village spared. But the Lonza River is now dammed. Over the last month it flew at ~5m3/s, expected to increase 2-3x in June. At 10 m3/s, it's 1M m3 every 28 hours.

I’ll be on @bbc5live.bsky.social at about 10:45pm UK time tonight discussing the Birch Glacier collapse and the impacts on Blatten, Swiss Alps. Looks to be a dangerous secondary hazard developing with the blockage of the Lonza River. #blatten #birchglacier #glacier www.bbc.co.uk/news/article...

SPEECHLESS BEFORE / AFTER #BLATTEN The magnitude of destruction after the 3:24 pm collapse of Birch Glacier is immense! 😱 All the forest has been razed and the ice/wood/debris dammed the Lonza river 🌊 Some buildings of Blatten are buried 🏠 📷 Pomona

❄️🏔️⚠️ Glacier collapse in the Swiss Alps has partially destroyed the village of Blatten, which thankfully had been evacuated already. #glacier #landslide #geohazard www.theguardian.com/world/2025/m...

❄️🌊Nice write-up of a Nature Climate Change paper by Jan Kavan et al. on coast development as Arctic glaciers recede. Includes some commentary from me. Enjoyed peer-reviewing the NCC article, writing a 'news and views' piece, and speaking to @ayeshatandon.carbonbrief.org about it all to top it off.

❄️ ⛱️ 🌊 NEW ARTICLE out today in Nature Climate Change: ‘Glaciers give way to new coasts’ This ‘News & Views’ article coincides with the UN International Day of Glacier Preservation. Arctic glacier recession has revealed ~2500 km of new coastline since the year 2000. www.nature.com/articles/s41...

The world's richest man - perhaps the richest man who has ever lived - gloating about shutting down aid for the world's poorest people. All while posing as the champion of the common man. The great lie of populism in its most naked and morally putrid form.

BBC news highlighting the damaging effects of glacial lake outburst floods (GLOFs) today. www.bbc.co.uk/news/article...

Sobering read in @natureportfolio.bsky.social about 1/6 chance of a major volcanic eruption this century w/ global climate impacts. Last time this happened (Tambora 1815) there was N hemisphere cooling of 1C, crop failures, social unrest 😬 Still 5/6 ain’t bad right? www.nature.com/articles/d41...

Feel like my data are trying to tell me something #middlefinger

I’m quoted in this Smithsonian Magazine article about glacial lake outburst floods (GLOFs). It follows from the ice-dammed lake drainage at Mendenhall Glacier, Alaska, earlier this year but covers other places affected by GLOFs. www.smithsonianmag.com/science-natu... #glofs #glaciers #geohazards

During the last six months there’s been a substantial increase in academics approaching me to ask about leaving #academia… This article articulates many of the reasons why they’re doing that…
