As the authors of the paper said in the abstract: «The minimal correlation between the contribution of AIS to GMSL by 2050 and that in 2100 and beyond implies
current sea level observations can not exclude future extreme outcomes.»
Their paper — titled «Ocean Bottom Deformation Due To Present - Day Mass Redistribution and Its Impact
on Sea Level Observations» — is published in Geophysical Research Letters.Here is the abstract:
«
Sea level observations are telling us that during the past 100 years sea level has risen at an average rate of 1.7 millimeters per year,» most of that due to thermal expansion as the top 700 meters of the oceans warms and expands.

Sea level observations will be assimilated by the TOPAZ forecasting system as soon as the calibration phase is completed, using the Ensemble Kalman Filter method developed by NERSC.
Taking into consideration
all sea level observations, the seas are not only rising, but that surge is accelerating [IPCC, 2013].
