Аннотация: Dynamics of active layer, one of the main parameters of the permafrost state, follows regional weather patterns. Compared to neighboring regions, Chukotka remains a white spot for monitoring data and recent trends in climate and permafrost dynamics. We made an update on changes in weather patterns and active layer thickness for 21st century. There is nearly no trend in regional summer warmth in 2000-2015, on the contrary with 1980-90s. Following it, thickening of the active layer have faded on the many sites, likewise in the neighboring regions: Alaska and NE Siberia. Lavrentiya and Lorino are the only exception with the trends of 7 cm per decade owing to location on icy loams. Given the activation of thermoerosion in vicinities of the plot, we suppose it is a feedback to preceding warming.
