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."

Ein KI-Modell des #AWI soll helfen, den globalen #Kohlenstoffkreislauf besser zu verstehen – von den tropischen #Regenwäldern bis zum tauenden #Permafrost.
Komplexe Rückkopplungen im #Erdsystem sollen besser erfasst und fundiertere Prognosen ermöglicht werden. Mit großen Datenmengen, etwa der #Erdfernerkundung und Biomasse-Infos, wird das Modell trainiert.

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.

You Did What?!
The Hole We Can’t Fix
By Cliff Potts, CSO, and Editor-in-Chief of WPS News
Baybay City, Leyte, Philippines — June 24 , 2026What Is Happening
In northeastern Siberia, a massive permafrost collapse known as the Batagaika crater continues to expand as warming temperatures thaw previously frozen ground. The formation, sometimes referred to as a “mega-slump,” is the largest of its kind currently observed.
The process is driven by thermokarst activity: once ice-rich permafrost begins to thaw, the ground loses structural integrity, collapses, and exposes deeper layers to further warming. This creates a feedback loop in which collapse accelerates additional thaw.
Why It Matters
The crater is not simply a geological curiosity. Permafrost contains large amounts of ancient organic material. As it thaws, that material decomposes and releases carbon dioxide and methane into the atmosphere.
This contributes to a broader climate feedback cycle:
- Thawing permafrost releases greenhouse gases
- Greenhouse gases increase global temperatures
- Higher temperatures accelerate further thaw
The visible collapse in Siberia is therefore part of a larger system that extends beyond the region itself.
What It Reveals
At the same time, the collapse is exposing layers of soil, plant material, and animal remains that have been preserved for tens of thousands to more than 200,000 years.
These layers provide direct access to:
- Past climate conditions
- Ancient ecosystems
- Long-term environmental change
Under normal circumstances, this information would remain buried and inaccessible. The current exposure creates a rare opportunity for scientific study.
A Global Opportunity
The site raises a practical question: how should the scientific community respond?
Research in such environments is already conducted through international collaboration. Scientists from multiple countries contribute expertise in geology, paleontology, climate science, and environmental analysis.
Access to the site is limited by geography, safety concerns, and national jurisdiction. However, the knowledge gained is global in value, not local.
The situation suggests a need for coordinated study rather than isolated effort.
The Balance
There is a tension in how to interpret what is happening.
The cause of the collapse—rapid warming and permafrost thaw—is destabilizing and carries long-term consequences. At the same time, the exposure of ancient material provides valuable insight into Earth’s past.
Both conditions exist simultaneously.
This is not a case of a beneficial discovery. It is a case of a damaging process that produces useful information.
Perspective
The expansion of the Batagaika crater is measurable, ongoing, and difficult to reverse at a local level. Once initiated, the thaw-collapse cycle tends to continue as long as environmental conditions support it.
That makes the site less a singular event and more a visible indicator of a broader trend.
Similar processes are expected to occur in other permafrost regions as warming continues.
Conclusion
The ground in Siberia is opening, exposing a long record of Earth’s environmental history while also releasing carbon that contributes to further change.
The situation presents a choice: treat it only as a warning, or also as a source of knowledge.
When conditions cannot be immediately reversed, understanding them becomes part of the response.
When life hands you lemons, around here you make calamansi and squeeze it over the barbecue.

Eilisessä Kokkolan Talviharmonikan konsertissa kantaesitettiin Cecilia Damströmin haitarikonsertto Permafrost, ikirouta, https://areena.yle.fi/podcastit/1-67590395
Ihan kiva kuunneltuna. Oli kuulimma kuvaakin mukana, ja sitten tietysti selitystä (etenkin perästäpäin). Solistina toimi Sonja Vertainen, ja Keski-Pohjanmaan kammariorkesteria johti Jan Söderblom.
Tuo kappale alkaa 25 minuutin ja päättyy 44:n kieppeillä.

Already at today’s 1.2°C global warming, we cannot rule out that the ice sheets of #Greenland and #WestAntarctica may pass their TPs eventually, resulting in several meters of committed long-term #SeaLevelRise, and that parts of #Permafrost become subject to abrupt thaw. /5

Klimawandel: Tauender Permafrost in den Alpen lässt Berghütten bröckeln -
Let’s get personal, shall we? I’ve been here a while now, and as I’m feeling quite comfortable at Mastodon, I’d like to share a bit more about myself beyond my passion for the climate and the environment.
To begin with, I’m a male, he/him, hetero, strongly supporting LGBTQ rights. I’m a baby boomer, born at 312 PPM 🌏, a United Statesian, although I lived in Europe (mostly Hungary) for several years, and traveled extensively for work before retiring in 2012. I’ve never been good at sustaining long-term romantic relationships, and I’ve finally settled into comfortable singlehood.
I like to say I’m made of contrasts.
For example, I’m rather funny and quite personable, but I don’t enjoy small talk and I hate parties. I currently live in the Bible Belt, but I’m an outspoken atheist. While I can easily fit into most social situations, I don’t feel comfortable around large groups and prefer being alone most of the time. I live near two huge military bases, but I detest the USA’s militaristic, troop-worshiping culture. I’m almost always cheerful, which masks my deeply felt existential nihilism. I’m a neat freak, but also rather lazy, preferring fun over work.
I’ll finish up with some hashtags to add flavor...
