«Global mean time series of surface - and satellite - observed low -
level and total cloud cover exhibit very large discrepancies, however,
implying that artifacts exist in one or both data sets... The surface - observed low -
level cloud cover time series averaged over the global
ocean appears suspicious because it reports a very large 5 % - sky - cover increase between 1952 and 1997.
... The recent cooling of the upper
ocean implies a decrease in the thermosteric component of sea
level.
If that was coming from the
ocean (70 % of the area), that would
imply 1.5 mm each and every year in sea
level loss.
Having said that, it is a really small effect — if the entire Arctic summer sea ice pack melted (average thickness 2 metres, density ~ 920 kg / m3, area 3 × 10 ^ 6 km ^ 2 (0.8 % total
ocean area) = > a 4.5 cm rise instantly which
implies a global sea
level rise of 0.36 mm.
As
implied in the article, the only way the
oceans can be maintained even at today's impoverished
level is by imposing severe restrictions on their use.
Second, he demonstrated that prevailing estimates of the 20th century GMSL rise (~ 1.5 to 2.0 mm / year), after correction for the maximum signal from
ocean thermal expansion,
implied mass flux from ice sheets and glaciers at a
level that would grossly misfit the residual GIA - corrected observations of Earth's rotation.

Levels 2 - 4 m Higher Until ~ 5,000 Years Ago
Imply Surface Temps Were At Least 5 °C Warmer According to the accepted (IPCC) formula for calculating the contribution of
ocean warming (thermal expansion) to sea
level rise upon reaching equilibrium, every additional degrees Celsius of surface warmth yields -LSB-...]
«Our results from this study
imply that if future anthropogenic warming effects in the Indo - Pacific warm pool dominate natural variability, mid-
ocean islands such as the Mascarenhas Archipelago, coasts of Indonesia, Sumatra, and the north Indian
Ocean may experience significantly more sea
level rise than the global average,» Han said.
This is achieved through the study of three independent records, the net heat flux into the
oceans over 5 decades, the sea -
level change rate based on tide gauge records over the 20th century, and the sea - surface temperature variations... We find that the total radiative forcing associated with solar cycles variations is about 5 to 7 times larger than just those associated with the TSI variations, thus
implying the necessary existence of an amplification mechanism, although without pointing to which one.
Indeed, the combination of a 10 degree temperature rise and the
ocean acidification from the increased CO2
levels that a 10 degree rise
implies, could very well lead to the mass extinction of most life on Earth.
«Global mean time series of surface - and satellite - observed low -
level and total cloud cover exhibit very large discrepancies, however,
