“…Such degradation is already being observed in many areas of the Arctic in response to the greater than average warming occurring in this region (Åkerman and Johansson, 2008;Sannel et al, 2016;Olvmo et al, 2020;De La Barreda-Bautista et al, 2022;Borge et al, 2017;Luoto and Seppälä, 2003;Sannel and Kuhry, 2011). The loss of permafrost and switch to waterlogged conditions represents a profound change in how this ecosystem functions, driving increased CH4 emissions which has been observed across many Arctic landscapes (Miglovets et al, 2021;Varner et al, 2022;Glagolev et al, 2011;Walter Anthony et al, 2016;Walter et al, 2006). To understand fully the magnitude of these feedbacks and their impacts on the global climate, it is imperative to both quantify current emissions and predict new areas that may become CH4 emitters across Arctic landscapes undergoing permafrost degradation.…”
