Abstract

Mismatch between acceleration of reconstructed sea levels and gradient of reconstructed temperatures

Author(s): Albert Parker

Sea levelrises faster as it getswarmer for the thermal expansion effect. Similarly, the ice melts faster as ice sheets and glaciers get warmer. Semi-empiricalmodels link the sea level rate of rise and the temperature change, and therefore the sea level acceleration to the temperature gradient. It is shown here that while the reconstructed temperatures of land and sea or land (GISS, ERSSTV3b) exhibit a quasi-60 years periodic oscillation with very likely another longer termperiodicities, the reconstructed global mean sea level (CSIRO) is a monotonically increasing curve.While the sea level accelerationmatches the gradient of anthropogenic carbon dioxide emission, the mismatch with the temperature gradient is evident.
