Impact of extreme warming in 2023 on permafrost in northwestern Canada / S.L. Smith, H.B. O'Neill, C. Duchesne, R.J.H. Parker, and J. Chartrand. : M41-11/183-2025E-PDF

"The preliminary results indicate that shallow ground temperatures in summer 2023 were generally warmer than 2022 and among the warmest on record at many sites in the Mackenzie Valley. Increases in thaw depth also occurred although still less than the increase that occurred in 1998. The increase in thaw at ice-rich sites that occurred between 2022 and 2023 resulted in an increase in surface settlement. More detailed analysis will provide further insights into the impacts of extreme warming in 2023. These results in combination with analysis of the impact of other extreme warm years will improve understanding of the impact of climate change and variation on permafrost environments in northern Canada"--Summary.
