The long-term tide gauge datasets are all in agreement that there is no acceleration
Wenzel and Schröter (2010) and Ray and Douglas (2011) report that there is no significant acceleration of GMSLR in their time series. On the other hand, Jevrejeva et al. (2008) evaluate the acceleration of GMSLR as about 0.01 mm yr−2 for 1700–2003, while Church and White (2011) find 0.009 ± 0.004 mm yr−2 for 1900–2009. Church and White (2006) report an acceleration of 0.013 ± 0.006 mm yr−2 for 1870–2001 in an earlier version of the dataset of Church and White (2011). In this paper, we do not show results for the earlier version, but we have analyzed it in the same way as the other four tide gauge time series and the results are close to those we obtain for the later version.
