Widespread and Rapid Activities of Retrogressive Thaw Slumps on the Qinghai‐Tibet Plateau From 2016 to 2022
Abstract Retrogressive thaw slumps (RTSs), formed by abrupt degradation of ice‐rich permafrost, are widely distributed on the Qinghai‐Tibet Plateau, causing infrastructure damage and enhancing soil carbon emissions. We compiled annual RTS inventories across the plateau from 2016 to 2022 using a deep...
