The Arctic is warming more strongly than any other region on Earth, which leads to serious erosion of coasts where organic matter was frozen in the permafrost for thousands of years. Once [...] Once eroded material is released into the ocean, microorganisms break down ancient plant remains, releasing sizable quantities of greenhouse gases. Yet, as the latest analyses conducted by AWI experts show
