                        WELL,  AT  LEAST  IT'S  NOT  FLAT

Citing a retracted paper  by a noted Bangladeshi Professor Emeritus of groundwater hydrology,  Ron Clutz of Science  Matters tells  Judith Curry's readers at Science Etc.  not  to worry about sea level rise, as it will mostly float the boats in Arctic  and Antarctic waters. 

The retracted paper argues that :

Global warming and polar ice-melt not contribute to sea level rise.
Melting of huge volume of floating sea-ice around polar region cool ocean-water preventing thermal expansion.
Polar ice melting re-occupy same volume of the displaced water causing no sea level rise.
Gravitational attraction of the earth plays a dominant role against sea level rise.
Melting of land ice in the polar region allow crust to rebound elastically for isostatic balancing through uplift should cause sea level to drop relatively.

Centrifugal force acts as much on the oceans as it does on the solid Earth, which is maximum at the equator and minimum at the pole (Fig. 4B). Any addition of water to the oceans is supposed to flow uphill towards equator from the poles causing sea level rise everywhere, but it does not

Hence, although ocean water at the equator makes a level difference of 21 km higher than at the poles, it is the centrifugal force maximum at the equator and zero at the poles would prevent ocean water-column from moving down-hill toward poles effectively restricting sea level rise at the higher latitudes...  ocean water column from polar region would not move towards equatorial region.
  Were it but  so,  the rancorous debate about EU scientists jetting to tropical climate conferences could be swiftly resolved. Residents of Northern climes could simply put on their water skis and slide down the Gulf Stream  to Cancun.

I shudder to think what  the inevitable corrigendum may look like :
