Hi all, this is a breath of fresh air ! I mostly sit in the UK daydreaming of the times I have been lucky enough to do things like this 😍 A dingle day in Antarctica, courtesy of @antarcticsurvey.bsky.social
Mountain glaciers are warming more slowly than their surroundings because of changes in debris cover and wind speed, which insulate them. However, new statistical analysis suggests that this "decoupling" will end in the coming decades, when they will melt more rapidly

Mountain glaciers recouple to atmospheric warming over the twenty-first century - Nature Climate Change
It has been argued that air temperatures over mountain glaciers are decoupled from surrounding warming, which could slow down melting. Here the authors show that this effect will weaken with future glacier retreat, leading to a recoupling of temperatures from the 2030s onwards.

44 science talks, bakeoffs, painting, archery, drone radar training, fell running, and a quiz. It can only be the @cpom-uk.bsky.social annual meeting at the magnificent YHA Castleton ! Thanks to all CPOM friends and family for making it such a fun event. Looking forwards to next year already 😊

Siberian cave deposits show that the Arctic was permafrost free 8.7 million years ago when the climate was 4.5C warmer with 130 billion tons more C02 in the atmosphere. Nice work @speleoseb.bsky.social

Cave Deposits Reveal a Permafrost-Free Arctic - Eos
Mineral cave deposits from northern Siberia show that the region was permafrost free during the late Miocene period, when Earth was warmer than today.

Fantastic new study in Science brings together a suite of model predictions
Glacier melting will continue for centuries, even if climate warming stops today
Our mountain landscapes will be unrecognisable if we continue to burn fossil fuels as we are today

Fantastic field week with 100+ First Years in the Lake District! Hills, tills, rocks, land-and soundscapes, and so much more. I fear we used up our 5-year sunshine quota tho 🌞😎
