[...] The IPCC estimates of sea-level rise may be even less accurate that we are led to believe…. When Wöppelmann et al. factored their measurements of land motion into the estimate of sea-level rise, they determined a global value of 1.31 ±0.30 mm per year compared to the 1.8±0.5 mm per year value given by the IPCC for the recent half century. We understand that the IPCC acknowledges a low-end value of 1.3 mm per year in their estimate, but another way to look at this article is that Wöppelmann et al. just reduced observed sea-level rise by 27%! Perhaps the IPCC should reconsider whether they still have high confidence that the rate of sea level rise has in fact increased from the 19th to the 20th century.

Of course, these results gained absolutely no press coverage whatsoever – imagine the coverage they would have received had their results increased sea-level rise by 27% and suggested that sea level rise was occurring faster then previous research indicated!
