Expansion of the Sahara Desert and shrinking of frozen land of the Arctic. [PDF]

, 2020
Expansion of the Sahara Desert (SD) and greening of the Arctic tundra-glacier region (ArcTG) have been hot subjects under extensive investigations. However, quantitative and comprehensive assessments of the landform changes in these regions are lacking ...

A Statistical‐Process Hybridized Approach to Modeling Permafrost Distribution in a Boreal Wetland Ecosystem, Whatì, NT, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT High‐resolution mapping of permafrost in ecologically and topographically complex landscapes remains a major challenge. Existing models of permafrost extent often rely on equilibrium assumptions, which can misrepresent conditions in regions where permafrost persists largely due to ecosystem structure.

Research progress and perspectives on ecological processes and carbon feedback in permafrost wetlands under changing climate conditions

Fundamental Research
Permafrost wetlands are closely related to potential greenhouse gas emissions under climate warming. In recent decades, climate change and human activities have induced extensive permafrost degradation, severely influencing the stability of wetlands in ...

Regulatory Framework and Public Policies for Sustainability in the Construction Sector

Sustainable Development, EarlyView.
ABSTRACT This study analyzes the role of public policies in promoting socially responsible practices in the construction sector, with a particular focus on their contribution to climate neutrality and the decarbonization of the building stock. European agreements exert increasing pressure to transform the construction sector, reinforcing the transition

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.

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 ...

Distribution and Degradation Processes of Isolated Permafrost near Buried Oil Pipelines by Means of Electrical Resistivity Tomography and Ground Temperature Monitoring: A Case Study of Da Xing’anling Mountains, Northeast China

Remote Sensing, 2023
Human engineering activities and climate warming induce permafrost degradation in the Da Xing’anling Mountains, which may affect the distribution of permafrost and the safety of infrastructure. This study uses the electrical resistivity tomography method,

Climate extremes relevant for permafrost degradation

, 2020
<p>During the past several decades, Arctic regions warmed almost twice as much as the global average temperature. Simultaneously in the high northern latitudes, observations indicate a decline in permafrost extend and landscape modifications due to permafrost degradation.
