Dynamics of the temperature regime of permafrost soil in the vicinity of the main gas pipeline taking into account climate warming [PDF]
arXivAn initial-boundary value problem for an unsteady two-dimensional heat conduction equation in a bounded domain modeling the unsteady temperature distribution of permafrost soil in the vicinity of a main gas pipeline, taking into account climate warming, is investigated.

Coastal Upwelling Enhances Winter Arctic Ocean Methane Emission
Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.Abstract As sea ice becomes thinner and more fragile, it may affect the Arctic Ocean methane budgets in winter. Using satellite, in situ and reanalysis data, the oceanic emissions of methane over the Chukchi Sea coast from 2003 to 2023 are investigated.

No protection of permafrost due to desertification on the Qinghai–Tibet Plateau
Scientific Reports, 2017 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 recent reports that state desertification protects

Convection in the active layer speeds up permafrost thaw in coarse grained soils [PDF]
arXivPermafrost thaw is a major concern raised by the ongoing climate change. An understudied phenomenon possibly affecting the pace of permafrost thaw is the onset of convective motions within the active layer caused by the density anomaly of water. Here, we explore the effects of groundwater convection on permafrost thawing using a model that accounts for

arXiv, 2005 Some microbes appear to be able to metabolize in glacial ice or permafrost. The rate depends on temperature, nutrient level, and bioelement availability, among other factors. I have developed a plausible argument that they do this while confined in veins filled with acidic or saline solution that provides nutrients and elements necessary for growth ...

The Effect of Structure Building Small Mammals in a Shifting Arctic Landscape
Ecology and Evolution, Volume 15, Issue 6, June 2025.We examined the effects of structure builders on biogeochemical cycling under future arctic tundra conditions. We found that structures influence nutrient availability and vegetation communities differently between contemporary and future conditions.

Environmental Policy and Governance, Volume 35, Issue 3, Page 397-415, June 2025.ABSTRACT Over the past decade, The People's Republic of China has increased its influence in global climate governance. Despite the strong interest in policy frames related to climate change at the global level, few studies have explored policy frames within China.

Unified analysis of algorithms for equilibrium, non-equilibrium, and hysteresis models of phase transition in permafrost [PDF]
arXivIn this paper we consider a nonlinear partial differential equation describing heat flow with ice-water phase transition in permafrost soils. Such models and their numerical approximations have been well explored in the applications literature.

River Discharge, in Chapter 5, Arctic, State of the Climate in 2010 [PDF]
, 2011 Several large-scale climate patterns influenced climate conditions and weather patterns across the globe during 2010. The transition from a warm El Niño phase at the beginning of the year to a cool La Niña phase by July contributed to many notable events,
