Tourism in the Arctic is at risk due to intensifying permafrost degradation

Communications Earth & Environment
Climate change is destabilizing Arctic landscapes by accelerating permafrost degradation, leading to more frequent slope failures, especially during summers.

Critical constraints to ecological buffering in a rapidly changing Arctic: A long‐term seabird study

Journal of Animal Ecology, EarlyView.
Drawing on two decades of research in East Greenland, this study shows that little auks, key seabird indicators of Arctic ecosystem health, can adapt to rapid environmental change through behavioural flexibility. However, increasing storms and mercury pollution are pushing resilience to its limits, providing an early warning of broader Arctic ...

Environmental Impacts of permafrost degradation

, 2019
Permafrost underlies approximately 50% of the Canadian landmass and is found in offshore areas beneath the Arctic shelf. Permafrost is warming at depth through taliks, along faults and methane leakage maybe enhanced from historical exploration wells and is also degrading in some areas as the surface active layer is thickening.

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Seismic Performance of Bridge Pile Foundation Considering Effects of Material Freeze-Thaw Deterioration and Permafrost Degradation

Zhongwai Gonglu
In cold and high-seismic regions, such as the Qinghai‒Xizang Plateau in China, the deterioration of material properties caused by freeze-thaw cycles and permafrost degradation due to climate change have become increasingly severe, posing significant ...

InSAR-measured permafrost degradation of palsa peatlands in northern Sweden [PDF]

The Cryosphere
Climate warming is degrading palsa peatlands across the circumpolar permafrost region. Permafrost degradation may lead to ecosystem collapse and potentially strong climate feedbacks, as this ecosystem is an important carbon store and can transition to ...

Spatial and Temporal Vegetation and Peat Depth Patterns in Alpine, Subalpine and Montane Peatlands of South‐Eastern Australia

Ecological Management &Restoration, Volume 28, Issue 1, January 2027.
ABSTRACT Alpine, subalpine and montane peatlands provide important ecosystem services, including carbon storage, water regulation and habitat provision, and are threatened by a range of disturbance and degradation processes that impact these services.

Response characteristics of vegetation and soil environment to permafrost degradation in the upstream regions of the Shule River Basin

Environmental Research Letters, 2012
Permafrost degradation exhibits striking and profound influences on the alpine ecosystem, and response characteristics of vegetation and soil environment to such degradation inevitably differ during the entire degraded periods.

Science Needs for a Terrestrial Biosphere Tipping Point Early Warning System

Reviews of Geophysics, Volume 64, Issue 4, December 2026.
Abstract Tipping points in the Earth system have the potential to cause major detrimental impacts to the biosphere and societies. Their inherent nonlinearity implies that even relatively small additional increases in external forcing might result in disproportionately large adjustments to components of the Earth system.

Recent advances in hydrology studies under changing permafrost on the Qinghai-Xizang Plateau

Research in Cold and Arid Regions
Due to the great influences of both climate warming and human activities, permafrost on the Qinghai-Xizang Plateau (QXP) has been undergoing considerable degradation.
