The Sea Level Enigmatic Rising -- New Perspectives from an Expanding Globe

Abstract

In the expanding Earth framework it is possible to find additional phenomena that could contribute in a proper way to the water balance and general tectonic eustatism involved in the sea lever rising. Recent compilations seems to leave unexplained up to 12 cm/century of sea rising, and possible solutions invoking a polar ice shells melting near to the upper limit of the error bars reveal in confict with the consequent expected decreasing of the Earth angular velocity. It is shown that taking into account possible effects of an expanding Earth, the problem can be initiated towards an appropriate solution, at least as regards the just orders of magnitude. Major effects on sea-level could come from ongoing relaxation of curvature variations that are peculiar for an expanding globe.
