«However, Fig. 15 and the associated uncertainties discussed in Section 3.4 show that long term estimates of time variable sea level acceleration in 203 year global reconstruction are significantly positive, which supports our previous finding (Jevrejeva et al., 2008a), that despite strong low frequency variability (larger than 60 years) the rate of sea level rise is increasing with time.» (skepticalscience.com)
«Because of the presence of low - frequency variations (e.g., multi-decadal variations seen in some tidal gauge records; Chambers et al. (2012)-RRB-, sea level acceleration results are sensitive to the choice of the analysis time span. (skepticalscience.com)
The study found that the most important approach to the earliest possible detection of a significant sea level acceleration lies in improved understanding (and subsequent removal) of interannual (occurring between years, or from one year to the next) to multidecadal (involving multiple decades) variability in sea level records.
