Vandstanden i verdenshavene – et paradoks afløser et andet

Here we revisit estimates of twentieth-century GMSL rise using probabilistic techniques9, 10 and find a rate of GMSL rise from 1901 to 1990 of 1.2 ± 0.2 millimetres per year (90% confidence interval). Based on individual contributions tabulated in the Fifth Assessment Report7 of the Intergovernmental Panel on Climate Change, this estimate closes the twentieth-century sea-level budget. Our analysis, which combines tide gauge records with physics-based and model-derived geometries of the various contributing signals, also indicates that GMSL rose at a rate of 3.0 ± 0.7 millimetres per year between 1993 and 2010, consistent with prior estimates from tide gauge records

Kommer tilbage med mere om cycler i vandstanden på et tidspunkt - jeg ar opdaget noget interssant.....

Jeg har ikke kunnet konstatere acceleration af vandstanden ud fra satellit data fra Colerado University. Dette skyldes formodentlig en for kort tidshorisont i sammenhæng med størrelsen af den forventede acceleration og forskellige månecykler dvs. 8.85 og 18.6 års cykleren.

The observed nodal cycle shows a pattern that is more E–W [east-west, NAN], rather than the equator–poles pattern of the equilibrium. The nodal cycle [18,6 års månecyklus] can thus be safely ignored for global mean sea-level estimates based on satellites
