We are waking up a monster, not in a novel but for real. One of the consequences of the #climatecrisis is the irreversible thawing of #permafrost.
Excellent article: readable & relevant.

Extreme #Hitze und tauender #Permafrost destabilisieren die französischen Alpen.
Im Mont-Blanc-Massiv wurden 2026 bereits 450 Felsstürze registriert. Der bisherige Höchstwert von 300 stammt aus 2022. Neben dem Permafrost-Abbau erhöht auch der Gletscher-Rückgang die Gefahr instabiler Felswände.
Mehrere Menschen kamen in diesem Sommer bereits durch #Felsstürze ums Leben. Behörden rufen #Bergsteiger zu besonderer Vorsicht auf.

“Permafrost soils are particularly vulnerable to climate change. To assess and improve estimations of carbon (C) and nitrogen (N) budgets it is necessary to accurately map soil carbon and nitrogen in the permafrost region. In particular, soil organic carbon (SOC) stocks have been predicted and mapped by many studies from local to pan-Arctic scales. Several studies have been carried out at the Canadian Beaufort Sea coast, though no regional maps of terrestrial carbon stocks based on spatial modelling has been conducted yet. This study combines available field data from the Canadian Yukon coastal plain and uses it to map regional SOC and N stocks using the machine learning algorithm random forest and environmental variables based on remote sensing data. [The authors] developed models using the data for the entire region and separate models for the coastal mainland area and Qikiqtaruk Herschel Island. Each model was used to map SOC and N stocks for its respective area. [They] assessed the performance of the different random forest models by using crossvalidation. [They] further assessed model results using the Area of Applicability (AOA) method and the quantile regression forest approach, comparing the results and discussing their implications within the context of both methods. [They] explore[d] local differences in soil properties and how soil data distribution across the region affects the accuracy of the predictions of SOC and N stocks..."

Tauender #Permafrost erhöht die Gefahr von #Bergstürzen in den Schweizer #Alpen.
Oberhalb von #Kandersteg könnten sich am Spitze Stei bis zu 20 Millionen Kubikmeter Gestein lösen. Eine unmittelbare Gefahr für das Dorf besteht derzeit nicht.
Der Berg wird kontinuierlich überwacht, Evakuierungspläne liegen vor. Steigende Temperaturen lassen #Permafrost und #Gletscher tauen und können dadurch Berghänge destabilisieren.

Siberia's growing methane threat could offset 20% of global methane reduction targets by 2050
The #Arctic is warming at an accelerating pace. As #permafrost thaws across vast areas and wildfires become more frequent, large amounts of #methane (CH4) are being released. Together, these changes are reshaping the region's #GreenhouseGas emissions and further intensifying climate change.
In a study published in Science on August 6, an international team led by Professor Liu Yi from the Institute of Atmospheric Physics #IAP of the Chinese Academy of Sciences investigated how #CH4 #emissions in #Siberia are evolving under #ClimateChange. The study showed how atmospheric circulation promotes #wildfire activity and #methanogenesis and thereby drives the recent sharp rise in CH4 emissions.

Am #Matterhorn ist es nach anhaltender Hitze und einem schneearmen Winter zu einem massiven #Felsabbruch gekommen.
Augenzeugen-Videos zeigen, wie große Mengen Stein und Geröll als Staubwolke ins Tal stürzen. Das Ereignis verdeutlicht die Veränderungen in den #Alpen.

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.

“Why the increase?
Our understanding of climate risk is only as good as our understanding of our exposure to hazards. The better we can account for what is at risk, the better we can measure risk in a changing world.
In this new study [link above], [they] investigate[d] how damage to the building stock across the Arctic, a key impact of permafrost degradation, is underestimated because of underdeveloped exposure information. With National Science Foundation (NSF) supercomputers and 400 TB of Vantor satellite imagery, [they] detected building footprints across the Arctic and classified their use types using deep learning models. Then, using Polar Geospatial Center's ArcticDEM digital surface model, [they] estimated the total floor space of each residential building. This move from 2D to 3D representation of the building stock was the largest contributor to increased building damage.
Properly estimating this consequence is necessary for understanding the near future of the Arctic economy. Knowing the magnitude of damages is critical for sustaining the communities and livelihoods of more than 5 million people that call the Arctic home. There are also much broader implications. With the Arctic continuing to emerge as a strategic centerpiece in global affairs and the global economy, accurately quantifying the physical shocks to its built environment will allow researchers to more effectively represent the Arctic in global climate economic models. More precise international policymaking will also be enabled by these improvements.
Ultimately, this research highlights a similar challenge in completely different regions of the world (e.g., Southeast Asia, Sub-Saharan Africa) where exposure is constantly evolving alongside rapid population growth and urbanization. Building stock information can quickly become outdated as these changes occur; satellite remote sensing and AI are key players in keeping up with these changes and supporting data-driven disaster risk management…”

Doch, Sven, das geht. Wir müssen nur alle #Sümpfe trockenlegen und das #Methan abfangen. Kann ja nicht so schwer sein. Der #Permafrost ist eh schon am abtauen. Einfach ein paar Kuppeln drüber und eine Absauganlage dran.

The absorption of carbon by #permafrost will peak in the next years, because of climate feedback.
"In a low emission scenario, permafrost carbon emissions increase the risk of northern high latitudes becoming a net carbon source by more than 50 % at 2 °C of warming[…]. Fire emissions can further weaken the sink by reducing its resilience to warming."
Varney, R. M., Hooke, D., Steinert, N. J., Smallman, T. L., Mathison, C., and Burke, E. J. (2026). "Northern high latitudes could become a net carbon source below 2 °C global warming", https://doi.org/10.5194/esd-17-913-2026

https://www.theguardian.com/world/2026/jul/03/canada-alberta-pipeline. 150 billion #Canadian $ more spent on an #oil #pipeline, @GeraldKutney? Is this how Mark #Carney & his #Government demonstrate their concern about the #climate #emergency? So, #wildfires don't happen in #Canada, & the #permafrost isn't melting? Mr Carney obviously doesn't care that Canada produced 13.42 tonnes of #CO2 per capita in 2025 (https://ourworldindata.org/search?topics=CO2+%26+Greenhouse+Gas+Emissions&countries=Canada).
