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

Abstract

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.
