TL;DR: In this paper, the authors investigated the biophysical effects of temperate land-management changes and revealed a net warming effect of similar magnitude to that driven by changing land cover, and found that potential surface cooling from increased albedo is typically offset by warming from decreased sensible heat fluxes.

TL;DR: In this article, the effects of permafrost thaw on lakes and streams in the Arctic were explored, where the authors explored the effect of both thermokarst (thawing and collapse of ice-rich permaculture) and deepening of the active layer (the surface soil layer that thaws and refreezes each year).
Large methane emissions from a subarctic lake during spring thaw: Mechanisms and landscape significance
TL;DR: The ice cover season and subsequent spring thaw are thought to be of particular importance for the biogeochemical cycle of northern lakes and wetlands as discussed by the authors, yet the magnitude of their methane emissions is unknown.

Testing the applicability of neural networks as a gap-filling method using CH 4 flux data from high latitude wetlands
Sigrid Dengel,Donatella Zona,Donatella Zona,Torsten Sachs,Mika Aurela,M. Jammet,Frans-Jan W. Parmentier,Walter C. Oechel,Timo Vesala +8 more
TL;DR: In this paper, the authors applied artificial neural networks to six distinctively different CH 4 time series from high lati- tudes, explain the method and test its functionality, and dis- cuss the applicability of neural networks in CH4 flux studies, the advantages and disadvantages of this method, and what information they were able to extract from such models.
Year-round CH 4 and CO 2 flux dynamics in two contrasting freshwater ecosystems of the subarctic
M. Jammet,Sigrid Dengel,E. Kettner,Frans-Jan W. Parmentier,Martin Wik,Patrick M. Crill,Thomas Friborg +6 more
TL;DR: In this article, the authors measured surface-atmosphere exchange of CH4 and CO2 during 2.5 years in a thawed fen and a shallow lake of a subarctic peatland complex.
