Two decades of observations capture rapid warming of marginal permafrost across the 0 °C threshold

Marginal warm permafrost is nearing 0 °C, but its transition across this threshold remains poorly constrained by limited long-term observations. We analyzed up to two decades of ground-temperature records from 59 boreholes on the northeastern Qinghai–Xizang Plateau, including four sites undergoing advanced degradat...
