NOAA 2012 report finds sea levels rising at less than half the rate claimed by the UN IPCC

‘The report compares sea-level rise calculated from two different methods: 1) satellite altimetry and 2) ARGO measurements of the steric [thermal expansion] component + GRACE measurements of ocean mass. The rate of sea level rise using the 2nd method [ARGO + GRACE] shows a sea level rise of only 0.2 {ARGO] + 0.1 [GRACE] = 0.3 mm/yr. Only by adding on a relatively large and highly questionable GIA adjustment [based on a model] of 0.9 mm/yr to the GRACE data do the two estimates come close to agreement. Following this questionable GIA adjustment, the ARGO + GRACE estimate is 1.1± 0.8 mm/yr as compared to the satellite altimetry estimate of 1.3 ± 0.9 mm’
