Early Holocene permafrost retreat in West Siberia amplified by reorganization of westerly wind systems
Abstract Rapid permafrost degradation and peatland expansion occurred in Eurasia during the Early Holocene and may be analogous to the region’s response to anthropogenic warming. Here we present a 230 Th-dated, multiproxy speleothem record with subdecadal sampling resolution from Kyok-Tash Cave, at...

Abstract Rapid permafrost degradation and peatland expansion occurred in Eurasia during the Early Holocene and may be analogous to the region’s response to anthropogenic warming.
