High frequency of glacial lake outburst floods (GLOF) driven by global warming
Overall, the long-term trajectory of reported GLOF frequency closely parallels variations in global air temperature, exhibiting a lag-correlated pattern on timescales of ~20 years.

High frequency of moraine-dammed lake outburst floods driven by global warming - Nature Communications
The study presents an updated global inventory of glacial lake outburst floods, revealing a sharp rise in event frequency since the 1980s and a strong delayed link to climate warming, highlighting gro...

Very strong turnout this morning on the first of our five days strike.
On Friday, in a meeting with the interim Principal, he confirmed his ideology is to cut as many jobs as possible.

These low-angle glacier detachments are, mercifully, rare, but can be incredibly destructive. Good review here, though several events since it was published in 2021: tc.copernicus.org/articles/15/...

Random thought. Thailand could pass for a glacier. Nice wide accumulation zone (though struggling in the mid section)

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.

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! 😮

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

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.
