BACKGROUND: Permafrost, ground that remains frozen for two or more consecutive years, covers vast areas of the Arctic. It stores enormous amounts of organic carbon, accumulated over millennia from dead plants and animals. When permafrost thaws, this organic matter decomposes, releasing greenhouse gases like carbon dioxide (CO2) and methane (CH4) into the atmosphere. This process creates a positive feedback loop, where warming causes thawing, which releases more greenhouse gases, leading to further warming. CURRENT CONTEXT: In early 2026, new satellite data and ground-based studies from Arctic regions indicate an accelerated rate of permafrost thaw, exceeding previous projections. Scientists are observing increased thermokarst formation (land subsidence due to melting ice-rich permafrost), coastal erosion, and the release of ancient microbes. The rate of methane release, a potent greenhouse gas, is particularly concerning. This accelerated thaw is impacting Arctic ecosystems, threatening infrastructure built on permafrost, and raising alarms about its contribution to global warming. The implications extend beyond the Arctic, with potential impacts on global weather patterns and sea levels. IMPACT/SIGNIFICANCE: The accelerated permafrost thaw is a critical tipping point in the Earth's climate system. The release of stored carbon and methane significantly amplifies global warming, making it harder to meet climate targets. It also poses risks to Arctic biodiversity, indigenous communities, and infrastructure. For competitive exams, understanding the concept of permafrost, the feedback loops associated with its thaw, the specific greenhouse gases released, and its global implications is essential.
