Climate and Permafrost Shifts in Yakutia’s Arctic and Subarctic from 1965 to 2023
LandBy analyzing the last 50–60 years of climate changes in Arctic and Subarctic Yakutia, we have identified three distinct periods of climate development.

Winter Ecosystem Respiration and Sources of CO2 From the High Arctic Tundra of Svalbard: Response to a Deeper Snow Experiment [PDF]
, 2018 Currently, there is a lack of understanding on how the magnitude and sources of carbon (C) emissions from High Arctic tundra are impacted by changing snow cover duration and depth during winter.

Eastern Beringia and beyond: Late Wisconsinan and Holocene landscape dynamics along the Yukon Coastal Plain, Canada [PDF]
, 2012 Terrestrial permafrost archives along the Yukon Coastal Plain (northwest Canada) have recorded landscape development and environmental change since the Late Wisconsinan at the interface of unglaciated Beringia (i.e.

Fast response of cold ice-rich permafrost in northeast Siberia to a warming climate
Nature Communications, 2020 Siberian Arctic permafrost contains vast stores of carbon, the fate of which is dependent on the climate. Here the authors use models of future scenarios to show that under the direst climate changes up to 2/3 of the stored organic carbon could thaw.

Influence of Rainfall Changes on the Temperature Regime of Permafrost in Central Yakutia
Land, 2021 Climate change effects, such as melting of glaciers and sea ice in response to rising temperatures, may lead to an increase in global water availability and thus in precipitation.

Stress‐Induced Melting Controlled Failure Mechanisms of Methane Hydrate
Advanced Science, EarlyView.We study methane hydrate via nanoindentation and nuclear magnetic resonance (NMR), finding its regional melting and mechanical properties, challenging existing views on hydrogen‐bonded crystals. Abstract Methane hydrate, a kind of nonstoichiometric crystalline, attracted worldwide attentions as a promising substitute energy. Its Dissociation is thought

Exploiting CO2‐Derived Carbon in Lithium‐Ion Batteries
Advanced Energy and Sustainability Research, EarlyView.In this work, a carbon nanomaterial (CNM) extracted from CO2 reduction treatment is used as the conductive additive in lithium‐ion battery graphite anodes and LiFePO4 cathodes. The electrodes are produced by casting, using both sodium alginate as a green, water‐soluble, alternative binder.

How do the environmental extremes of Siberian permafrost soils shape the composition of the bacterial soil community? [PDF]
, 2007 Microbial communities in permafrost soils of the Siberian Arctic are exposed to extreme environmental conditions. The soils are frozen throughout the entire year except for the short summer period, when thawing of the uppermost 20 to 50 cm of the ...

The Anatomical Record, EarlyView.Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...
