A small #outcrop of the #Squantum Member of the #Roxbury #Conglomerate

These #rocks are in the #BostonBay Group, which is currently dated to #Neoproterozoic. The Squantum Member was interpreted as a #tillite, possibly associated with the #Gaskiers #glaciation, although there a scant signs like scratched pebbles or faceted cobbles. It is currently commonly interpreted as a #debrite (debris flow). Details in captions.

Sad news in the Austrian media about the “death” of the Pasterze Glacier, once the largest in country. I went directly to this location at the start of my last sabbatical, as a pilgrimage of sorts. The #glacier was breath-taking, even if the signs of rapid retreat were overwhelming. Now the tongue of #ice in the valley has completely detached from the accumulation area higher up. Another indication of how dramatically things are changing in the #mountain #cryosphere

Icebergs coming out of the Icefjord into Disko Bay from Ilulissat glacier in West Greenland. At the end you can see where the sill (bump on the sea floor) is at the mouth of the fjord where all the big icebergs are getting stuck. #icebergs #icefjord #glacier #greenland

Can cast shadows be used to infer changes in glacier elevations? Yes, they can. Check out our new paper in The Cryosphere and this blog post: https://topotoolbox.wordpress.com/2023/08/24/shadows-reveal-changes-in-glacier-surface-elevations/

It's #MountainMonday and #10YearsAgo we fulfilled one of our dreams. What a weekend, what an experience... we were indestructible 🤠

We climbed Ortler (3905m, also called Ortles), the highest mountain in #SouthTyrol, in the region of #Tyrol, and the former Austro-Hungarian Empire.

We had great weather, a great company, and an astonishing panorama.

NOAA reporting about August 2023 flooding in Juneau Alaska. “Not every retreating glacier in Alaska is at risk for these glacial lake outburst floods, but those that are can have very serious consequences downstream. …

For the Mendenhall Valley, glacial lake outburst floods are a relatively new phenomena but have become a yearly occurrence since 2011, when the first outburst occurred.”

#SouthAmerica's scorching winter is decimating #crops and threatening lives

Story by Marina E. Franco, August 15, 2023

"This winter in South America has been one of the hottest on record, intensifying crises created over the last year by severe #droughts, #wildfires and #floods in some regions.

"Why it matters: Experts say the #Extremeweather is already threatening critical #biodiversity and the lives of millions in a region where many reside in slums or informal housing with little #infrastructure.

"Threat level: Much of the northern hemisphere has experienced deadly #heatwaves and weather disasters this summer. July was the hottest month on record.

"In South America, the 'hot' winter effect stems both from the El Niño phenomenon that warms ocean temperatures and from man-made #globalwarming says Alejandro Max Pastén, head of hydrological prediction at Paraguay's Weather Service.

"'What's being done so far to stem this is either not yet panning out or simply not enough, and the effects are increasingly plain to see,' adds Pastén, who also leads the atmospheric sciences department at Paraguay's Universidad Nacional de Asunción.

"Extreme weather has caused significant reductions in crops for local consumption and for exports, which contribute to many of South America's economies. For example, drought has slashed #Argentina's #soybean yields to the lowest in 24 years, threatening its status as world's largest exporter of #soybeanoil and meal.

"Increased and irregular #glacier melting has put lives and livelihoods in danger since many people depend on regular meltoff for drinking water and #agriculture. It is also used to supply #hydroelectric power generation, which could be affected as glacier water becomes more scarce.

"The World Meteorological Organization has warned that a diminished hydroelectric power supply is increasing demand for fossil fuels in a region that has 'major untapped potential for #renewable energy.'

"What's happening: Heat waves have hit several South American nations since July, the second month of winter. The average temperature in #BuenosAires in early August is 59°F — this year it's been 86°. Temperatures in #Chile hit 100° this month.

"#ExtremeHeat has worsened drought conditions and also made the region more prone to dangerous landslides when it rains.

"Parts of #Uruguay have been under a 'water emergency' since June because of drought, and that same month #Bolivia had a mix of drought, heavy rains and frost."

The East GRIP coring has hit the base of the NEGIS ice stream of the Greenland Ice Sheet, finding the glacier is underlain by mud, thus confirming the role of sediment deformation in its dynamics. Undoubtedly this was challenging to pull off, considering the glacier is flowing several centimeters per day. #Greenland #Glacier #IceSheets https://news.ku.dk/all_news/2023/07/pay-dirt-for-ice-core-scientists-in-east-greenland-as-they-reach-bedrock/

When I started my analyses in 2016, the #glacier was right in front of my plots. Now it is several 100m away.

#fieldwork #climatechange #alps

Had. Great field day. Got quite a few plots done. And I simply love the tiny but colourful plants in the #glacier forefields.

The Ibex were pretty fearless and foraged around while we were working.

Visiting #Norway 's National Museum I came across a photograph (top) of the #Briksdal #Glacier taken by Knud Knudsen in 1872.

A quick internet search led me to a photograph taken around 2018 from the same vantage point (bottom, credit jamie@explorewithed.co.uk)

The recession of the glacier is simply scary. What have we done?
