Is it true that permafrost thaws seasonally at the surface during summer?
Yes. Multiple reference and peer-reviewed sources state that the active layer above permafrost thaws seasonally during summer, including NASA and a PANGAEA dataset abstract. Regional field studies in Alaska, Siberia and the Mont Blanc massif further document seasonally thawed layers over permafrost.
