Why Is Arctic Permafrost Thawing 4x Faster Now?

🕐 7 min read  |  🌍 Natural Wonders 🔒 Key Takeaways Arctic permafrost stores 1.7 trillion tons of organic carbon—twice Earth's current atmospheric CO₂ content Methane from thawing permafrost is 25 times more warming-potent than CO₂ over 100 years Permafrost thaw rates accelerated 4x faster between 1990s and 2024, with active layers deepening 15–20 cm per decade in Siberia and Alaska Ground temperatures in Arctic permafrost zones rise 0.6°C annually—3–4 times the global average—triggering self-sustaining carbon-climate feedback loops Beneath the Arctic's frozen crust lies a carbon bomb ticking faster than predicted. Arctic permafrost thaw acceleration reveals an alarming reality: the ground in Siberia and northern Alaska is thawing 4 times faster than 1990s baseline measurements, unleashing 1.7 trillion tons of ancient organic matter trapped since the Pleistocene epoch. This acceleration is no longer a distant threat—2024 research confirms it's triggering a sel...
