Lower Curtis Glacier thinning and retreat continues. 8-6-2024 survey indicates 21 m retreat this year. Mass balance will again be quite negative.

Coleman Glacier on Mount Baker terminus survey 8-7-2024. Thinning on our 1988 profile line is ~40 m, nearly 1 m per year. Retreat over 600 m-more specific later.

Easton Glacier terminus 8-9-2024. 40 m retreat since last August from 2022 and from 1990 terminus location

Deepest crevasse today in Easton Glacier 82 feet

Ice caves at the top of a glacier are a study in decay. Here on what was Ice Worm Glacier 8-12-2024 images from Jill Pelto and I

Many Svalbard glaciers in August 2024 are snow free as was the case in 2022 and 2023. NASA Landsat 8-8-2024 image illustrates how widespread this is across Edgeoya and Spitsbergen. glacierchange.blog/2024/08/17/wid…

All glaciers labelled in the Nathorst Land and Nordenskjold Land region of Svalbard are snow free in 8-11-2024 Landsat image. Arwyn Edwards Neil Glasser Dr. Heïdi Sevestre USGS Landsat NASA Earth glacierchange.blog/2024/08/17/wid…

Either that or subglacial channels, which tend to be a bit curvy and long, what is the orientation with respect to flow and the margin?

Not a surprise to see that the ice cliffs themselves are not a stable enough feature to endure. If that were not the case more ice cliffs of this height would be observed today for longer periods.

Was never likely. If tall ice cliffs were a stable feature that could endure, they would exist more commonly around ice sheets now.

NOAA led State of the Climate 2023 report published in BAMS is out. The cover is a pair of images I took of a glacier that dissappeared in 2023 after 40 years of our continuous monitoring, overall the cryosphere not faring well.

This report filled with so much specific detail. Cover images taken by me of Ice Worm Glacier that disappeared in 2023 after we monitored forty years in a row.

These record highs driving the resulting record lows for mountain glaciers.

Always a key resource on the annual progression of climate change. Cover images of The loss of Ice Worm Glacier is a 40 year progression from stable size to gone. This summer the decay continued as remnant ice is hollowed out.

The Extinct glacier layer in GLIMS gets a shout out today from Capital Weather Gang in article from Kasha Patel Matthias Huss, Andrew Fountain and I sources. washingtonpost.com/climate-enviro…

These ice cave channels have become so commonplace now, they are a good study in glacier decay. Including caves starting from the top of the glacier as seen here at Ice Worm Glacier

On Aug. 4 we drilled stakes into Sholes Glacier using ice augur provided by Ben Pelto. Three weeks later melt had averaged 0.08 m per day. This is 36000 m3 per day of runoff for North Fork Nooksack River.

More examples of essentially snow cover free glaciers in Svalbard illustrated in Landsat images, such as on Storskavlen and Trollheimen. glacierchange.blog/2024/08/31/sva…

Digefonna Ice Cap, Svalbard is snow free as August 2024 ends. This further reduces the crucial firn covered area on the ice cap, leading to thinning and bedrock emerging in ESA Earth Observation image. Neil Glasser Dr Will D. Harcourt Arwyn Edwards Dr. Heïdi Sevestre glacierchange.blog/2024…

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.
