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.

#Siberia: Residents stunned after strange new formations appear across remote landscape: 'The landscape has become pockmarked'

by Zachary Ehrmann
Fri, May 16, 2025

"Thawing ground in Siberia's remote #YamalPeninsula is warping the landscape — and residents say the changes are becoming impossible to ignore. Strange mounds, sudden sinkholes, and even explosive craters are reshaping the #tundra, alarming locals and researchers alike, per the Malay Mail.

"These changes are tied to a disturbing trend beneath the surface: the rapid thaw of once-frozen ground, known as #permafrost.

What's happening?

"As Siberia warms at nearly four times the global average, vast stretches of permafrost are thawing. When this frozen ground melts, it releases methane gas from ancient organic material once safely locked beneath the surface.

"In the Yamal region, that gas is pushing the earth upward into large mounds that sometimes explode, tearing open the landscape and leaving behind deep craters.

"Innokenty Poselsky, who bought land in Churapcha, noted that he had about 20 mounds pop up but that it wasn't always like that. 'About 40 years ago, there was an airstrip here and the land used to be quite flat. Over the last four decades, the landscape has become pockmarked. It's like that everywhere here,' he told the Malay Mail.

"Local villagers, many of whom rely on the tundra for #reindeer herding, say their homeland has become nearly unrecognizable. One herder told researchers that familiar flatlands have been replaced by unpredictable swells and holes.

Why is the thawing of Siberia's permafrost important?

"Beyond changing the physical landscape, permafrost melt poses major threats to communities and the planet. Thawing ground can damage roads, #pipelines, and homes. #Methane, the gas being released, is over 80 times more potent than carbon dioxide in the short term. That means this process isn't just a local hazard — it's a global #climate risk.

"Thawing permafrost can also accelerate other problems. Warmer, wetter conditions can spread disease, disrupt food systems, and increase the severity of #ExtremeWeather events by adding more heat-trapping polluting gases to the atmosphere.

"While extreme events such as #wildfires and #floods aren't new, scientists agree that a hotter planet — caused by human activity, mainly the burning of #FossilFuels — makes them both more destructive and more frequent."
