This release of gases traps more heat, causing temperatures to rise further, which leads to more thawing, and the cycle perpetuates. Permafrost acts as a massive repository for organic carbon, accumulating over millennia from the frozen remains of plants and animals.
Infrastructure Damage From Thawing Permafrost
As microbes decompose the once-frozen carbon, they release carbon dioxide and methane, both potent greenhouse gases, into the atmosphere. Furthermore, the release of ancient carbon adds a significant, and currently unaccounted for, variable into global climate models.
Greenhouse Gas Global Warming Potential (20-year) Primary Source in Thawing Permafrost Carbon Dioxide (CO2) 1 Aerobic decomposition of organic matter Methane (CH4) 84 Anaerobic decomposition in wetlands and water bodies The repercussions of the permafrost feedback loop extend far beyond atmospheric chemistry. Methane is significantly more effective at trapping heat in the atmosphere than carbon dioxide over a 20-year period, making its release particularly concerning for the intensity of the feedback loop.
Infrastructure Damage From Thawing Permafrost
Permafrost, the perennially frozen ground that blankets vast regions of the Northern Hemisphere, is undergoing a profound transformation. Aerobic decomposition, which occurs in the presence of oxygen, typically produces carbon dioxide.
