Fennoscandia has been rising since the retreat of a massive glacier at the end of the Pleistocene. Although there are decades' worth of tide gauge records for the coast of Sweden and Finland, it has been difficult to extract an estimate of sea level rise by subtracting the ground surface uplift. Milne et al. (p. 2381) completed a 7-year global positioning system (GPS) campaign and combined these land-surface deformation measurements with the tide gauge records to derive a more accurate regional sea level rise of 2.1 ± 0.3 millimeters per year. This value is consistent with the global average and relevant to models of global warming. They also derived a refined viscosity for the mantle and an elastic thickness of the lithosphere, which are fundamental inputs for mantle convection and crustal flexure models.
