Shiny fresh snow, dirty Saharan dust, blueish ice. Impressive transition of surface types seen on Great Aletsch #Glacier yesterday from top down. The state of Swiss glaciers is still excellent this summer but snow melting is now accelerated by the albedo effect of reddish dust.

Deadline extended to 21 July 2024

We received this amazing footage from Professor Alun Hubbard showing rare meltwater upwelling and moulins on the Western Greenland Ice Sheet yesterday after five days of high temperatures & clear skies. Professor Hubbard commented, “Surface melt, upwelling & moulins kicking off

DESOLATION... 😭 As Svalbard climatology is reshaped by hitting >20°C two days in a row (2 degrees more than previous record!) this is what ice caps of the archipelago look like yesterday Endless bare ice! Not a single accumulation zone left 🔥 Pic Arwyn Edwards

Recent evolution of snow cover on the Adamello glacier. The abundant spring snow is rapidly disappearing. Saharan dust deposited with snow is also outcropping, accumulated at the surface by melting. Resume: a good accumulation season and a normal (in the new climate) summer.

Le Glacier Blanc, joyau des Écrins, majoritairement à nu dans ses parties inférieure et médiane après un été particulièrement chaud, à l'aube. Au refuge des Écrins (3170m), la dernière gelée sous abri remonte au 4 juillet, et c'est la seule (et faible -0,4°C) depuis le 17 juin.

Many examples this August of glaciers across Svalbard that have essentially lost all snow cover and where firn area has rapidly been lost, just one example of climate stress in Svalbard.

The terminus of Vadret da Morteratsch, largest #glacier of Eastern 🇨🇭, has completely changed in just 1 year. What used to be a gentle edge of the ice has retreated into a vertical 20 m ice wall with a river/lake in front. Scenic, but another brutal expression of climate change
