In the experiment on superfluid transport in solid He4 [PRL {\bf 100}, 235301(2008)], Ray and Hallock observed an {\it anomalously large isochoriccompressibility}: the supersolid samples demonstrated a significant andapparently spatially uniform response of density and pressure to chemicalpotential, applied locally through Vycor "electrodes". We propose that theeffect is due to {\it superclimb} : edge dislocations can climb because of masstransport along superfluid cores. We corroborate the scenario by {\it abinitio} simulations of an edge dislocation in solid He4 at $T=0.5K$. We arguethat at low temperature the effect must be suppressed due to a crossover to thesmooth dislocation.
