Extremes of summer climate trigger thousands of thermokarst landslides in a High Arctic environment

Retrogressive thaw slumps (RTS) are landslides caused by melting ground ice in permafrost areas. Based on Google Earth Engine Timelapse data, the authors show an unprecedented 60-fold increase in RTS numbers for Banks Island, Canada, from 1984 to 2015 due to a warming summer climate.
