One forcing with significant spatial variability is the present-day postglacial rebound signal, which results in falling LSL in the formerly glaciated areas and rising LSL in the areas of the former peripheral bulge and most of the farfield regions. We have geophysical models predicting this signal, which on time scales of several centuries can be considered to be linear. However, inter-model differences are large particularly in the regions where the peripheral bulge was located. There, uncertainties can exceed the 2 mm/yr level, resulting in uncertainties of up to 20 cm per century.
