Abstract

Permafrost thaw is accelerating globally, with significant impacts on ecosystems, infrastructure, and climate. This research synthesizes current understanding of the drivers and consequences of permafrost degradation. Key concerns include the release of greenhouse gases, landscape instability, and alterations in hydrological and biogeochemical cycles. The study underscores the urgent need for enhanced monitoring and modeling to predict future changes and inform adaptation strategies. Emerging risks such as the mobilization of contaminants and ancient pathogens are also highlighted.
