We reassess the importance of archaeological sea level indicators along the coast of central Italy (Figure 1), recently revisited within the European COST Action ES0701. It appears that the local sea-level rise since 2000 years ago can be estimated of the order of about half a meter, that agrees with the classical literature about this topic, rather than ~1.35 m, as recently proposed. In order to analyze the contribution of glacio-isostatic adjustment (GIA) effect to sea level rise detected with observations on field, we employ different viscosity of 0.5 x 10^21 Pa.s for upper mantle and 2.7 x 10^21Pa.s for lower mantle and several late-Pleistocene ice sheets chronologies. Neglecting the tectonic contributions to sea level variations and supposing a laterally uniform rheology, in these regions, RSL curves depart from eustasy mainly because of the effects of melt water loading, responsible for a widespread subsidence reaching its largest amplitude in the bulk of the basin. The mismatch between observations from field data and model predictions can be partly attributed to the poor knowledge of the visco-elastic property of the mantle and to uncertainties of the details of the melting history. The residual between the observations and the predictions of RSL leaves some room for a contribution of recent sea level variations driven by climate change, which according to IPCC estimates amount to 30 cm globally averaged (IPCC, 2007).
