Section 1
Section 1 A Vicious Cycle The Arctic Is warming at nearly four times the global average rate, leading to the rapid thawing of permafrost.
Section 2
Section 2 This frozen ground holds massive stores of ancient organic matter.
Section 3
Section 3 As it thaws, microbes break down this material, releasing methane—a greenhouse gas significantly more potent than CO2 over a short timeframe.
Section 4
Section 4 Monitoring the Threat Scientists Are deploying satellite and drone technology to measure methane emissions from these remote regions.
Section 5
Section 5 The potential for a “tipping point” makes understanding and mitigating this feedback loop a top priority.
