Permafrost warming, driven by rising air temperatures and changing snow regimes, is amplifying global climate change. A global dataset of permafrost temperature time series from the Global Terrestrial Network for Permafrost (GTN-P) was used to evaluate temperature changes across permafrost regions from 2007 to 2016. The study found that ground temperatures near the depth of zero annual amplitude increased by 0.39 ± 0.15 °C in continuous permafrost zones, 0.20 ± 0.10 °C in discontinuous permafrost zones, 0.19 ± 0.05 °C in mountain permafrost, and 0.37 ± 0.10 °C in Antarctic permafrost. These changes follow the Arctic amplification of air temperature increase in the Northern Hemisphere. In the discontinuous zone, ground warming was primarily due to increased snow thickness, while air temperatures remained statistically unchanged. The observed trends highlight the urgent need for improved representation of permafrost dynamics in Earth System Models to better predict future climate feedbacks.Permafrost warming, driven by rising air temperatures and changing snow regimes, is amplifying global climate change.
