Analysis of groundwater flow through low-latitude alpine permafrost by model simulation: a case study in the headwater area of Yellow River on the Qinghai-Tibet Plateau, China
Warming climate and thawing permafrost have profound impacts on groundwater flow regimes in cold regions because of the shrinkage or disappearance of the confining unit formed by the permafrost layers and impr...

Map** the permafrost stability on the Tibetan Plateau for 2005–2015
Data scarcity is a major obstacle for high-resolution map** of permafrost on the Tibetan Plateau (TP). This study produces a new permafrost stability distribution map for the 2010s (2005–2015) derived from t...

Historical changes in the depth of seasonal freezing of “**ng’anling-Baikal” permafrost in China
“**ng’anling-Baikal” permafrost is located in the southern edge of the Northern Hemisphere permafrost, which is one of the most important regions of permafrost changes. Based on the monthly meteorological data...

Open AccessPermafrost is warming at a global scale
Permafrost warming has the potential to amplify global climate change, because when frozen sediments thaw it unlocks soil organic carbon. Yet to date, no globally consistent assessment of permafrost temperatur...

Open AccessNo protection of permafrost due to desertification on the Qinghai–Tibet Plateau
Desertification of tundra regions may form an escalating cycle with permafrost degradation where more permafrost thaw leads to continued desertification. This traditional viewpoint has been challenged in recen...
