To assess these implications, we translate global into local SLR projections using a model of spatial variation in sea - level contributions caused by
isostatic deformation and changes in gravity as the Greenland and Antarctic ice sheets lose mass (36 ⇓ — 38), represented as two global 0.5 ° matrices of scalar adjustment factors to the ice sheets» respective median global contributions to SLR and (squared) to their variances.
