Current and Quaternary data on sea level. (A) The current sea surface height measured by satellites (Hamlington et al., 2021, fig. 2) shows trends to lower sea level in the polar regions and sea level rise in tropical regions. That is, oceanic water transfers from the polar regions to the tropics. If we assume that these forces last for a thousand years, the rise in the maximum points would reach 10 m and in three thousand years would be enough to reach 30 m. (B) This could have occurred, in addition to the Holocene, in MIS 5.5 and MIS 11. The sea level rises recorded in the eastern Canaries have occurred approximately every 1500 years (Meco et al., 2018). Independent of the volume of ice, the distribution of seas and continents, the rotation of the Earth and the astronomical symmetry of the Earth-Moon intervene in this process. Meco et al., 2022.
