Elevation dependency of future degradation of permafrost over the Qinghai-Tibet Plateau

Environmental Research Letters, 2023
Global warming has caused widespread permafrost degradation, but the geographic regularity of permafrost degradation is unknown. Here, we investigated the three-dimensional features of future permafrost degradation on the Qinghai-Tibetan Plateau.

Impacts of permafrost degradation on infrastructure

Nature Reviews Earth & Environment, 2022
Abstract The warming and thawing of ice-rich permafrost pose considerable threat to the integrity of polar and high-altitude infrastructure, in turn jeopardizing sustainable development. In this Review, we explore the extent and costs of observed and predicted infrastructure damage associated with permafrost degradation, and the methods available to ...

The influence of permafrost degradation on the change of suprapermafrost water : A case study in the source areaof the Yellow River

Shuiwen dizhi gongcheng dizhi, 2023
The supra-permafrost water is a vital water source to support the ecosystem and an important link in maintaining the hydrothermal cycle in the permafrost area.

Degrading permafrost and its impacts

Advances in Climate Change Research, 2021
Abstract Permafrost presents extensively on the land surface and it is degrading under the combined influences of warming climate and human activities. The degrading permafrost will post profound impacts in hydrology, ecology, engineered infrastructures, and socioeconomic development. In order to better adapt to these changing permafrost environments,

Thermal Regime and Variations in the Island Permafrost Near the Northern Permafrost Boundary in Xidatan, Qinghai–Tibet Plateau

Frontiers in Earth Science, 2021
Although the thermal regime and degradation of permafrost on the Qinghai-Tibet Plateau (QTP) have been widely documented, little information exists regarding the island permafrost in the area. Ground temperatures were therefore measured for 8 years (2013–

Onshore Thermokarst Primes Subsea Permafrost Degradation [PDF]

Geophysical Research Letters, 2021
Abstract The response of permafrost to marine submergence can vary between ice‐rich late Pleistocene deposits and the thermokarst basins that thawed out during the Holocene. We hypothesize that inundated Alases offshore thaw faster than submerged Yedoma. To test this hypothesis, we estimated depths to the top of ice‐bearing permafrost

Permafrost Degradation and Its Hydrogeological Impacts [PDF]

Water, 2022
Under a warming climate, permafrost degradation has resulted in profound hydrogeological consequences. Here, we mainly review 240 recent relevant papers. Permafrost degradation has boosted groundwater storage and discharge to surface runoffs through improving hydraulic connectivity and reactivation of groundwater flow systems, resulting in reduced ...

Impacts of climate-induced permafrost degradation on vegetation: A review

Advances in Climate Change Research, 2021
Under a warming climate, degrading permafrost profoundly and extensively affects arctic and alpine ecology. However, most existing relevant studies are more focused on the hydrothermal impacts of vegetation on the underlying permafrost, or symbiosis ...
