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.» (realclimate.org)
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: (breitbart.com)
These long ‐ term sea level observations show that GMSL rose slower during the 20th century. (judithcurry.com)
