PQP "oxidação" de rios!

"O degelo deste solo [o permafrost], causado pelo aquecimento global, gera erosão, libera resíduos tóxicos em lagoas e rios, ameaça liberar microrganismos perigosos, assim como potenciais emissões de carbono retidos no gelo há milhares de anos.

Esse solo congelado está presente sob grandes partes do Alasca, Canadá e Sibéria, onde comunidades indígenas vivem, trabalham e caçam há centenas de anos e sofrem lentamente os impactos do aumento da temperatura global.

O degelo da camada de permafrost remodela paisagens, desloca vilas inteiras e fragiliza habitats de animais."

"This is by far the most horrific flood I have ever seen"

Himalayan glacier expert Alton C Byers on what happened in Nepal and what should happen now

We're getting more and more insights. What we can say for sure is that this is different from your classic glacial lake outburst flood. What we had was a massive breakage of ice and rock from high on Langtang Lirung on the Nepal side of the border with Tibet. It plummeted down and, in effect, was the catalyst for a series of cascading events. I think that the breakage was related to changes in #permafrost, which has become vulnerable to warming trends. Permafrost was the #cryosphere glue that held these mountains together for millennia, and we're seeing more massive breakages of snow and ice and rock as well.

The world’s vast permafrost regions contain three times more carbon than all living vegetation. Some are thawing and emitting more and more greenhouse gases.

#Permafrost cannot refreeze back. "Once you pass the permafrost’s threshold and the ice has gone and the landscape has changed, it is not going to come back for hundreds of years. On a human timescale, those systems have then effectively tipped into a system that will keep emitting carbon for decades or centuries."

"Unfortunately, there are no feasible geoengineering solutions on a broad scale. The only way to limit the thawing of millions of square kilometres is to reduce emissions rapidly. We need to act urgently."

“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..."

“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…”

“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…”

Risiko für irdische „Heißzeit steigt
Klimaforscher warnen: Destabilisierung des Klimasystems wird wahrscheinlicher

#Klimaforscher warnen: Das #Erdklima könnte dem Übergang zu einer neuen #Heißzeit näher sein als gedacht. Denn durch die zunehmende #Erwärmung und steigenden #Treibhausgas'werte hat sich das Risiko für ein Umkippen mehrerer Stellschrauben im #Klimasystem weiter erhöht. Positive #Rückkopplungen und #Fernwirkungen über Kontinente hinweg könnten dann einen #Kaskadeneffekt auslösen, der das Erdklima destabilisiert. Dann könnte die Erde in einen neuen Zustand geraten, der nach menschlichen Zeitmaßstäben irreversibel ist – eine Heißzeit.

Einige der Klima-Stellschrauben könnten schon jetzt in ein neues Gleichgewicht gekippt sein. „Dies ist der Fall bei den Eisschilden #Grönland's und der #Westantarktis, für den borealen #Permafrost und die #Berggletscher“, berichten die Forscher. Auch der #Amazonas-#Regenwald stehe kurz vor dem Umkippen.

Weird. Maybe, I've got a logical mistake in my thinking

Will #Steffen et al 2018 https://www.pnas.org/doi/10.1073/pnas.1810141115 warned in "Trajectories of the Earth System in the Anthropocene" of a "Hot House Earth" .
A term that got negative press all over and the paper is still discredited in public opinion among the non-scientific community, at least.
A Hot House Age is merely the term for an ice-less age in which the poles are not covered by kilometres of ice. That is called an Ice House Age.

#Talento et al 2021 https://esd.copernicus.org/articles/12/1275/2021/ modelled what happens to ice ages #glacial |s in several emission scenarios.
Today's CO2 concentration is already moving the next #iceage to later than what the #Milankovic cycles would dictate.
Scenarios for (in my opinion fictitious, unachievable) emissions of 1000 or 3000 Pg C move the next fullblown ice age to 600ky and 900ky from now.
Almost a million years. No ice age.

But the #AMOC is going to collapse: the convection in the Subpolar Gyre in the 2030s; the Northern branch of AMOC might tip before 2050 to later inevitably collapse, too.

Certainly that increases ice mass in Greenland, Europe, and Eurasia, and Arctic Sea Ice grows back, too. And all this AMOC-related ice grows and grows, each year puts more snow on the ever increasing ice layer.
I don't know how much ice is needed to meet criteria for a glacial definition.
But all that Eurasian ice also buries the boreal forests under it, ie removes their carbon from the cycle. And puts an ice plug on leaking methane from #permafrost in that area. (Tho not the permafrost in the far East. I gather, that area is not prone to ice sheets from Atlantic influences and needs other triggers to form? It wasn't covered by ice in #MIS11, 420ky ago. )

Weird isn't it, that ice mass models like Talento's don't factor in ever-increasing ice mass in low-to medium emission scenarios. Hm.

"Kryosphären-Bericht: Deutlich weniger Schnee und Eis in Österreich"
https://science.orf.at/stories/3222889/

"Die aus den Messungen belegten markanten Veränderungen der Kryosphäre würden die enorme Temperaturzunahme in den Alpen seit ca. 1980 widerspiegeln."

"Die seit den 1880er-Jahren um rund zwei Grad Celsius gestiegene mittlere Jahrestemperatur in Österreich führe zum Auftauen des Permafrosts. Dessen zuvor stabilisierende Wirkung auf Grate, Schutthalden oder Felswände lasse bereits bei Erwärmung deutlich nach „und ist aktuell nur mehr deutlich reduziert gegeben“, heißt es in dem Bericht."

"Das fehlende Eis [auf Seen] hat nicht nur Auswirkungen auf den Tourismus, sondern auch auf wichtige Ökosystemprozesse in Seen."

"Geplant ist künftig eine jährliche Erscheinungsweise der Analyse, die heuer vom Klimaministerium gefördert wurde. Allerdings fehle ein Förderinstrument für ein regelmäßiges Kryosphären-Monitoring in Österreich, heißt es in dem Bericht." #IWüsGorNetWissenNetSoGenau
