Why use individual tide gauge records when we have perfectly good combinations, from much larger samples, which give a global picture of sea level change and show vastly less noise? (skepticalscience.com)
This is a global data set, and it's a worldwide average so its shows vastly less noise than individual tide gauge records. (skepticalscience.com)
Second, by using individual tide gauge records, the noise level is so high that you can't really hope to find acceleration or deceleration of any kind, with any consistency. (skepticalscience.com)
