-year evolution of retrogressive thaw slumps on the central Qinghai-Tibet Plateau
View through CrossRef
Permafrost underlying the central Qinghai-Tibetan Plateau has experienced significant degradation in recent decades due to the warming climate. Retrogressive thaw slumps (RTSs), a typical form of abrupt permafrost disturbance, retreat rapidly and can impact the local environment for decades before stabilizing. Previous studies have revealed rapid growth of RTSs in the central plateau, with their areas and numbers increasing by 154% and 70% from 2016 to2022, respectively. To gain a deeper understanding of the long-term activity and distribution of RTSs, we utilized multi-source satellite imagery, including Keyhole (1965–1984), Landsat (1984–2015), WorldView (2006–2013), and PlanetScope (2016–2024), to trace their activities over six decades. We manually delineated RTSs on high-resolution (
