Yes, Jimbo, people are aware of the WUWT site, and of the fact that people like you and Anthony take false comfort in the fact that during a significant chunk of the Holocene it was warmer than today, leading to a lot of ice melting, not just in the Arctic basin but on land, as well, causing sea levels to rise dramatically.

As Arctic sea ice melts earlier and freezes later each year, polar bears have a limited amount of time to hunt their historically preferred prey — ringed seal pups — and must spend more time on land.

So melting of ice on land, or precipitation from the atmosphere can only decrease the moment of inertia, so the rotation speeds up as land ice melts, and runs down to sea level.

In Northeast Land and Svalbard, the melting waters on the ice caps are the tears of the Earth mourning the future death of men and civilizations as the concentration of carbon dioxide in the atmosphere spikes and global warming proceeds rapidly, killing millions of marine organisms, and increasing the acidification of the oceans.

As to your original premise that the melting of polar (land) ice would slow down the rotation because of sea level rise in the equatorial regions, I am still thinking on that question.

In summary the melting of land ice floating on the ocean will introduce a volume of water greater than that of the originally displaced sea water, hence raising the water level a little.
