Microbial methanogenesis is a major source of the greenhouse gas methane (CH 4). It is the
final step in the anaerobic degradation of organic matter when inorganic electron acceptors …

Permafrost covers a quarter of the northern hemisphere land surface and contains twice the
amount of carbon that is currently present in the atmosphere. Future climate change is …

Permafrost thaw liberates frozen organic carbon, which is decomposed into carbon dioxide
(CO2) and methane (CH4). The release of these greenhouse gases (GHGs) forms a positive …

A prototype algorithm for hemispheric scale detection of autumn soil freezing using space-
borne L-band passive microwave observations is presented. The methodology is based on …

Methane emission feedbacks in wetlands are predicted to influence global climate under
climate change and other anthropogenic stressors. Herein, we review the taxonomy and …

Reductive dissolution during permafrost thaw releases iron-bound organic carbon to
porewaters, rendering previously stable carbon vulnerable to microbial decomposition and …

Temperature plays a significant role in anaerobic digestion (AD) as it affects the microbial
communities and ultimately controls the efficiency of the process. Few studies have looked …

Observations taken over the last few decades indicate that dramatic changes are occurring
in the Arctic‐Boreal Zone (ABZ), which are having significant impacts on ABZ inhabitants …

The thawing and subsidence of frozen peat mounds (palsas) in permafrost landscapes
results in the formation of organic‐rich thermokarst lakes. We examined the effects of palsa …

Methanogenic archaea are important for the global greenhouse gas budget since they
produce methane under anoxic conditions in numerous natural environments such as …
