Spatial response of retrogressive thaw slump initiation to differential warming. a Weighted 2-year July–August average air temperature at three official climate stations on Banks Island: Sachs Harbour (1984–2015), Thomsen River (1998–2015) and Nangmagvik Lake (1997–2015). b Total active retrogressive thaw slumps in southern (≤72.16°N—red line), central (72.17–73.23°N—blue line) and northern (>73.23°N—purple line) zones. Inset map shows the boundaries of the three zones, the location of the three climate stations, and retrogressive thaw slumps first observed in 2012
