New member but regular reader. Perhaps all that heat is spread around more, rossby waves or whatever, and melting the permafrost and causing fires instead. If polar vortex takes cold downsouth in winter it could take summer heat and consistent wind patterns away too. All I read about permafrost focuses on methane release, whereas if one were to take permafrost and whole arctic into account and measure permafrost as ice and give total ice melt(how to measure this is beyond me) then one could measure total energy going into this and see energy available annd where rossby waves moved it. Essentially the ice pack breakdown has eliminated the concept of arctic as such, which was, as we now know, a function of stable rossby waves. Total energy, cold in winter, warm in summer, strong wind action, moves around whole northern hemisphere(mostly N.. America?) so that the linear predictability is gone.so if instead of focusing on ice we add the permafrost melt and average water temp. and average land temp above arctivc circle(ca. Fairbanks ) we might be getting somewhere. In other words I have a freezer at home and I open the freezer door. Now it cools the whole room, which is insulated say but less coolness per area. Rossby waves are the door. When all permafrost is melted for always then and only then will all ice be meltable and ice and permafrost will be gone year round only together. Our focus is too narrow.
