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."

Feedback of global warming:

"We treat each WIE source independently and do not account for interactions between them, such as permafrost thaw expanding wetland extent through thermokarst formation, or the recursive effect where WIE-induced warming itself drives further WIE".

"For CO2, which accumulates in the atmosphere, a sustained emission rate produces a radiative forcing that increases over time, so the cumulative impact on carbon budgets depends on the duration of elevated temperature, not just the magnitude of warming. When we evaluate our permafrost CO2 results to compare with the AR6 framework, we find that the correction terms are 60, 123, and 138 Pg CO2 ℃⁻¹ for SSP1-2.6, SSP2-4.5, and SSP4-6.0, respectively".

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 , 2026

What 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.

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 , 2026

What 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.

Rock Weathering Can Counteract River CO2 Emissions Induced By Permafrost Thaw

“[The researchers] measured carbon emissions and water chemistry in 50 headwater rivers draining 780,000 km² of the Tibetan Plateau.
The rivers flow in landscapes underlain by continuous permafrost and landscapes in which the permafrost has retreated since the last glacial maximum. They collect[ed] organic carbon from soils and dissolved inorganic carbon that is fixed by rock-weathering.
Where the permafrost cover is continuous, rivers emit CO2 from degrading (permafrost) soil carbon. Weathering reactions in these catchments are relatively slow.
In landscapes with (almost) no permafrost, carbon fluxes from weathering are faster than CO2 emissions from rivers.
Thus, as permafrost landscapes transition to landscapes without permafrost cover, chemical weathering reactions may play an ever more important role in riverine carbon cycling.
Interestingly, weathering can affect the carbon cycle in different ways. Where sulfide minerals are present, weathering reactions can emit CO2. Where silicate minerals dominate, weathering draws down CO2 from the atmosphere…”

“Climate-induced permafrost thaw unlocks large stores of organic carbon that are mineralized and emitted as carbon dioxide (CO2) from rivers to the atmosphere. Concurrently, warming and permafrost thaw can increase mineral weathering rates, thus affecting the release and sequestration of inorganic carbon. Yet how these biological and geological carbon cycles interact and jointly affect CO2 dynamics (emission compared with drawdown) in permafrost rivers remains unknown. Here [they] combine[d] CO2 emissions, organic and inorganic solute concentrations, dual carbon isotopes (δ13C–Δ14C) and geochemical modelling to infer how permafrost thaw may affect river biogeochemistry over decades to centuries across the Qinghai–Tibet Plateau. Leveraging a gradient of thermal permafrost degradation, we find that river CO2 emissions decline, whereas solute fluxes from rock weathering increase with decreasing permafrost cover. Across this region, net CO2 drawdown fluxes from rock weathering are about 35% of river CO2 emissions, varying from around 15% in catchments with continuous permafrost to more than 100% in catchments with discontinuous or isolated permafrost. Thus, carbon fluxes from chemical weathering may become increasingly important with ongoing permafrost thaw, potentially even outpacing river CO2 emissions. [Their] findings disentangle the interplay between biological and geological carbon fluxes that are important for the cryosphere and the global carbon cycle…”
