Fig. 2

a–h Monthly mass change of the Arctic glacier systems from GRACE/GRACE-FO satellite gravimetry data for the time period 2002–2023 (blue), annual change of the mean active layer thickness from CCI permafrost data (2003–2019) for the region PEVE (green) (i) and at CALM station Samoylov (SAMO) for 2002–2023 (yellow) (j) as departure from the long-term mean. Uncertainties are shown as two standard deviations (± 2σ; shading). The respective rates of glacier mass change (Gt yr−1) and rates of active layer thickness change (cm yr−1) for each region are indicated along with ± 2σ uncertainties in panels a–j. Changes are shown with respect to the 2003–2019 mean.
