#Permafrost ist ein wichtiges Puzzleteil im Ökosystem der #Arktis: Er speichert Kohlenstoff über lange Zeiträume und bietet festen, stabilen Grund. Schmilzt das Eis, entstehen sogenannte Thermokarstseen.
AWI-Forschende haben nun die Datenbank "Lost Lakes" aufgebaut, die wichtige Informationen über den Zustand von Thermokarstseen der Arktis bereitstellt. Das ermöglicht es, Veränderungen in den Permafrostlandschaften zu erkennen, sobald sie passieren.

Very happy that today is the paperback publication day of my third novel, Rail: A High Speed Adventure! Thank you all who have supported this journey.
In Rail, a designer is drawn into a globe spanning infrastructure proposal with uncertain motives. As ecological ethics collide with corporate ambition, she must confront the meaning of home, responsibility, and legacy—while her past and future converge in unexpected ways.
The trilogy blends environmental storytelling, design thinking, and near future speculation, offering readers a grounded yet visionary look at the systems shaping our world. Chowdhury, a registered architect and circular economy strategist based in the Vancouver metro area, continues her exploration of ecological futures through character driven narrative and interdisciplinary worldbuilding.

“Can we develop a first-order understanding of permafrost degradation and glacial lakes exposed to degradation-induced mass movements in the Himalaya?
[The authors] tried to address this question. The study [first link above] integrates machine learning, statistical modeling, and numerical modeling to investigate high-resolution permafrost distribution, potential degradation, and associated mass-movement hazards in the Kinnaur district of Himachal Pradesh, India.
Using rock glaciers as proxies, [they] generated a high-resolution permafrost distribution using machine learning, while potential degradation zones were delineated using the 0°C isotherm as a first-order indicator. [They] further identified glacial lakes located near potentially degrading permafrost zones and reconstructed their bathymetry. A detailed scenario-based GLOF process-chain simulation was then carried out for Kashang Lake using r.avaflow and HEC-RAS.
[Their] results indicate that seven glacial lakes in #Kinnaur are located close to potentially degrading permafrost zones. The simulations further show that a potential GLOF from Kashang Lake could inundate critical downstream infrastructure, including nearly 11 km of National Highway 5…”

Permafrost Formation In A Meandering River Floodplain
--
https://doi.org/10.1029/2024AV001175 <-- shared paper
--
“... KEY POINTS:
• River meandering resets permafrost development and vegetation succession by eroding old floodplain areas and depositing new land
• On the Koyukuk River, permafrost rapidly forms in new deposits, but it takes over 4 Kyr to develop to its full areal extent of 85%
• The rate of permafrost formation is likely linked to vegetation succession on younger and overbank deposition on older floodplain areas…”

Der "Arctic Report Card 2024" zeigt alarmierende Veränderungen: Die letzten neun Jahre waren die wärmsten seit Beginn der Aufzeichnungen.
https://arctic.noaa.gov/report-card/report-card-2024/
Rekord-#Hitze und steigende #Niederschläge verstärken das #Abschmelzen der #Meereisfläche, das 2024 die sechstniedrigste Ausdehnung erreichte.
Auch der #Permafrost taut weiter auf, und die arktische #Tundra gibt mittlerweile mehr CO₂ ab, als sie speichert.

Die #MethanEmissionen sind in den letzten Jahren stark gestiegen und tragen erheblich zur #Erderwärmung bei.
Forscher vermuten, dass vor allem #Landwirtschaft, #Müllverwertung und #Feuchtgebiete die Hauptquellen sind. Steigende Temperaturen fördern das Wachstum von #Mikroorganismen, die #Methan freisetzen, besonders in #Feuchtgebieten und tauendem #Permafrost. Dieser sich selbst verstärkende Mechanismus könnte den #Klimawandel weiter beschleunigen.
-
Industrielle Altlasten im #Permafrost bergen erhebliche Gefahren. Durch das Auftauen des Permafrosts können giftige #Chemikalien und #Schwermetalle freigesetzt werden, die Boden und #Gewässer kontaminieren. Besonders betroffen sind abgelegene Gebiete, in denen die Überwachung und Sanierung schwierig ist. Das zunehmende Abschmelzen des Permafrosts durch den #Klimawandel verstärkt diese Risiken.

The #Batagay or #Batagaika crater in Siberia often referred to as the "Doorway to the Underworld" or the
"Gateway to Hell" is a
#permafrost #megaslump in Yakutia, Russia.Dimensions vary by source, but the site covers around 192 acres (78 hectares)
and stretches two thirds of a mile (one kilometer) in length.Logged of trees in the 1960s, its walls reach a depth of around 180 feet (55 meters)
and expose 650,000 years of geologic history.Since first spotted in the 1960s by surveillance satellites, the crater has grownfrom an insignificant gully to a massive depression at an accelerating rate.
According to Sarah Cadieux, Sr. Lecturer and Associate Director of Environmental Science of Rensselaer Polytechnic Institute,
the crater area increased by almost three times from 1991 to 2018.The Batagaika crater isn’t a crater at all,
it’s a #retrogressive #thaw #slump, a type of terrain called #thermokarst that occurs in areas underlain by permafrost.No longer cooled by forest cover, the slump has become a self-sustaining #feedback #loop,
a portion of the ecosystem which has tipped into a new state.This is not an isolated case, but rather a rapidly growing problem in the Arctic as
💥it warms three to four times the rate of the rest of the planet since 1979.Called Arctic or polar #amplification, this phenomenon is a well established fact measured by instruments,
confirmed in climate computer models,
and reinforced by paleoclimate records.Powerful anecdotal evidence occurred in the scorching heatwave of 2020 that saw the Russian town of Verkhoyansk
which lies north of the Arctic Circle hit a stunning 38° C (100.4° F) on June 20.2020 also saw overall temperatures in the Siberian basin rise to nearly 11° F above normal,
shocking scientists and releasing #ancient #methane
not from ancient organic material,
but from #limestone.Elevated methane in wetlands was expected, but not from #outgassing #rock.
A year later in 2021 Europe’s climate change service Copernicus Sentinel satellites recorded 118° F (48° C) in the Sakha Republic of Arctic Siberia,
and records continue to fall with temperatures over 100° F in 2023 as reported by CNN. -

#FossilAdventCalendar Day 22 (delayed due to time with the family)
Our first #fossil from north of the #Arctic Circle is from the most iconic of #IceAge #megafauna. This woolly #mammoth, Mammuthus primigenius, was found over a century ago in the far #north of Siberia and gifted to Paris' #MuseumNationalD'HistoireNaturelle by the tsar. Like the squirrel featured yesterday, this mammoth was partially preserved in #permafrost; you can see its #mummified face and leg in the case at the right.

#FossilAdventCalendar Day 21 (delayed by a busy travel day)
As we move towards the far #North we encounter one of the (literally) coolest kinds of #fossilization. When the #frozen ground known as #permafrost forms, it can #freeze dry #animals buried in it. This ground #squirrel, Urocitellus undulatus from #Alaska 🇺🇸 and displayed in the #AmericanMuseumOfNaturalHistory, burrowed into the ground in life and was #mummified by it after death, providing a remarkable window into life in the #IceAge.
