abstract = "{Time-variable satellite gravimetry constrains global glacier mass
change, but requires correction for glacial isostatic
adjustment. These corrections are commonly treated as slowly
varying background signals from past ice loading and assumed to
be separable from present-day glacier loss. Here we show that
this separation can fail in low-viscosity settings, where
viscoelastic rebound can approach isostatic compensation on
annual-to-decadal timescales and covary with ongoing ice
retreat. Using millennium-scale glacier reconstructions and
viscoelastic Earth modelling, we incorporate rapid rebound into
gravimetry trend inversions for Alaska and Iceland. This reveals
additional ice loss of \raisebox{-0.5ex}\textasciitilde7
{\ensuremath{\pm}} 1 Gt yr$^{{\ensuremath{-}}1}$ in Alaska and
\raisebox{-0.5ex}\textasciitilde3 {\ensuremath{\pm}} 1 Gt
yr$^{{\ensuremath{-}}1}$ in Iceland (2002--2025), with
uncertainties spanning Earth-model spread. Globally, gravimetry-
inferred glacier mass loss increases by
\raisebox{-0.5ex}\textasciitilde10 Gt yr$^{{\ensuremath{-}}1}$
(\raisebox{-0.5ex}\textasciitilde0.03 mm
yr$^{{\ensuremath{-}}1}$ global mean sea-level rise;
\raisebox{-0.5ex}\textasciitilde4\%), with
\raisebox{-0.5ex}\textasciitilde9\% more loss in Alaska and
about one-third more in Iceland. Similar inversion biases are
expected elsewhere in low-viscosity regions.}",
