A global perspective on local sea level change: A comment

We replicate Voortman and de Vos (2025). Although we unfortunately lack access to their data and code, we qualitatively reproduce their results. We argue that their null result-no significant acceleration of sea level rise in the tide-gauge record-is the result of a regrettably misread statistical correction. We show that their main conclusion is due to a lack of power: They estimate an overly complicated model on too few observations and use inappropriate statistical methods to do so. Estimating simpler models or pooling data, we find statistically significant acceleration.
