Global Sea Level Rise Has Decelerated 31% Since 2002, New Paper

A paper published today in Nature Climate Change finds that global sea level rise has greatly decelerated 31% since 2002 from 3.5 mm/yr to 2.4 mm/yr.

According to the authors, “This decreasing Global Mean Sea Level [GMSL] rate coincides with the pause observed over the last decade in the rate of Earth’s global mean surface temperature increase, an observation  exploited  [very unscientific choice of words] by climate sceptics to refute global warming and its attribution to a steadily rising rate of greenhouse gases in the atmosphere.”

[Apparently, the authors think that any skeptical scientist who points out an obvious inconsistency between datasets is exploiting the observational data.]

This observation, of course, is a crisis for CAGW alarmism and therefore must be solved by a computer model. The authors simply create a hydrological model programmed to say that the reason why sea levels have decelerated is because it must be raining more over land due to ENSO and therefore the land ate the 31% decrease in sea level rise [No mention why ENSO also didn't cause more rain over the oceans]. The authors admit there is no data to support land water stores prior to GRACE since ~2003, therefore they just fabricate estimate the comparison data for the period 1994-2002 of how much sea level rise was ameliorated by land precipitation. Abracadabra, the land must have more than eaten the sea level rise from AGW, allowing it to decelerate, and the AGW “missing heat” is still very much alive somewhere in the ocean.

The authors also find that even with this huge adjustment to sea level rise, there is no evidence of acceleration over the past 20 years, which means there is no evidence of a human influence on sea levels. 

The authors redeem themselves a bit in the conclusion and appear to contradict their earlier statements in the paper: “Although progress has been achieved and inconsistencies reduced, the puzzle of the missing energy remains, raising the question of where the extra heat absorbed by the Earth is going. The results presented here will further encourage this debate as they underline the enigma between the observed plateau in Earth’s mean surface temperature and continued rise in the Global Mean Sea Level [GMSL].”

Climate science has sunk just like the ‘missing heat’ to the depths of the ocean trying to explain away the “pause” of both global warming and global sea level rise, using synthetic data generated by climate models that can be programmed to obtain any result one desires.
