The long-term tide gauge datasets are all in agreement that there is no acceleration
One thing which is not a matter of opinion is that all these data sets show acceleration. Their rates go both up and down in a complex pattern, but for all of them, modern times are dominated by increasing rates. The presence of acceleration — both throughout the record and in the most recent decades — is testified by every one of these data sets. [...] For all the satellite data sets, we can see the acceleration if we study their residuals from a straight-line fit, but we don’t trust "looks like" — we go with the statistical tests. They’re unanimous: acceleration. [...] The latest series of posts (about sea level) started with Dave Burton denying the existence of acceleration in tide gauge records from individual stations. We proved him wrong; he refused to admit his mistake. Our recent look at the satellite data from NOAA/STAR was because Kip Hansen claimed it not only failed to show acceleration, it demonstrated the absence of acceleration. We proved him wrong too, and he has yet to admit his mistake. As often happens with climate deniers, when confronted with actual analysis he resorted to claiming the data he picked wasn’t good enough to do the job.
