Siberia's Batagay Megaslump: Permafrost Melt and Carbon Emissions

The Batagay crater in Siberia, the world's largest megaslump, is expanding rapidly due to thawing permafrost. This process releases thousands of tons of stored carbon into the atmosphere annually, creating a dangerous feedback loop that accelerates further warming. Beyond the climate impact, the collapsing terrain is revealing prehistoric remains, including a 50,000-year-old mammoth and extinct horse species. The site serves as a visible indicator of how rapid Arctic warming destabilizes the ground and releases ancient organic matter.

This is a clear example of a positive feedback loop. Permafrost thaws, releases carbon, warms the air, and then more permafrost thaws. The 5,000 ton annual carbon estimate is a specific data point that shows why these megaslumps matter for global accounting.

The real issue is that these natural emissions are rarely captured in national carbon budgets or policy targets. If the land itself becomes a massive emitter, the math for hitting net zero gets much harder for everyone.

The article mentions deforestation in the 50s and 60s triggered this. It makes me wonder how much of this is purely temperature driven versus land use changes. Does the data show a correlation between local canopy loss and the rate of slump expansion?

It says the area increased three times between 1991 and 2018. That is a massive jump in a short window. The prehistoric finds are interesting, but the volume of ground mobilized is the real story here.
