Over 2000–2021, ice discharge in this sector shows a statistically highly significant ( p < 0.001) negative trend while OTF shows a statistically highly significant ( p < 0.001) positive trend until 2019 (Fig. 3 b).

in sectors SE and S) ocean thermal forcing does not show a significant trend over 2000–2021 anymore.
Overall, the peripheral glaciers and especially the PTG have shown considerable retreat over the twentieth century 32 and afterwards 33 , and modelling studies found a negative trend of peripheral glacier-wide surface mass balance over the last three decades 34 , 35 .
We can further rule out decreased melt as a reason for glacier slowdown as ERA5 47 air temperature variability in sector NE shows a positive trend consistent with all other sectors.
