Regional Sea-Level Change along the Chilean Coast in the 21st Century

Abstract

ABSTRACT Albrecht, F. and Shaffer, G., 2016. Regional sea-level change along the Chilean coast in the 21st century. Regional sea-level change for Chile is considered until the end of the 21st century for the representative concentration pathway (RCP)4.5 and RCP8.5 scenarios. The main components that contribute to sea-level change are analyzed and summed to achieve a total estimate of sea-level change along the coast of Chile and in the Southeast Pacific. Included are the steric/dynamic component, the contribution from land ice loss, and the sea-level change due to the glacial isostatic adjustment. Regional fingerprints and global means are combined to estimate sea-level change in this area. For the steric/dynamic component two different estimates are considered. The results are compared with those found in the Intergovernmental Panel on Climate Change Fifth Assessment Report. The total mean sea-level rise along the coast lies between 34 cm and 52 cm for the RCP4.5 scenario and between 46 cm and 74 cm for ...
