TL;DR: In this paper, the authors find that current evidence suggests a gradual and prolonged release of greenhouse gas emissions in a warming climate and present a research strategy with which to target poorly understood aspects of permafrost carbon dynamics.

Abstract: Large quantities of organic carbon are stored in frozen soils (permafrost) within Arctic and sub-Arctic regions. A warming climate can induce environmental changes that accelerate the microbial breakdown of organic carbon and the release of the greenhouse gases carbon dioxide and methane. This feedback can accelerate climate change, but the magnitude and timing of greenhouse gas emission from these regions and their impact on climate change remain uncertain. Here we find that current evidence suggests a gradual and prolonged release of greenhouse gas emissions in a warming climate and present a research strategy with which to target poorly understood aspects of permafrost carbon dynamics.

A Sodium-Ion Battery Separator with Reversible Voltage Response Based on Water-Soluble Cellulose Derivatives.
TL;DR: This work provides novel cues for the development of biomass-derived porous membranes to function as battery separators, surpassing the performance of commercially available separators based on fossil resources in terms of capacity retention, Coulombic efficiency, homogeneous plating/stripping of Na and dendrite growth suppression.

TL;DR: In this article, the authors investigate for the first time recent global soil organic carbon (SOC) changes, based on some SOC stock interannual data that were processed for the 2001-2015 period on a planetary scale.

A novel approach for co-producing positive scenarios that explore agency: case study from the Canadian Arctic
TL;DR: In this paper, a set of methods for participatory scenario planning is proposed to carefully explore what "positive futures" could mean to different populations faced with growing impacts from environmental and social change, and how positive outcomes can be achieved even in light of these changing dynamics.

Trends in Satellite Earth Observation for Permafrost Related Analyses—A Review
TL;DR: The temporal development of publication frequency, utilized platforms/sensors and the addressed environmental topic is thereby highlighted, and the total number of publications more than doubled since 2015, while large portions of the continuous permafrost zone are still only sparsely covered by satellite remote sensing investigations.

The vertical distribution of soil organic carbon and its relation to climate and vegetation
TL;DR: In this paper, the authors examined the association of soil organic carbon (SOC) content with climate and soil texture at different soil depths, and tested the hypothesis that vegetation type, through patterns of allocation, is a dominant control on the vertical distribution of SOC.
