Comment on “Sea-level trend analysis for coastal management” by A. Parker, M. Saad Saleem and M. Lawson

A key conclusion of the article ‘Sea-Level Trend Analysis for Coastal Management’ (Parker et al., 2013) is that: l management should consider sea level rises much smaller than those based on modelling activities presently considered in Australia as well as in the other parts of the world at least for the next 30 years. The projections by the relevant state bodies should therefore be revised considering lower bounds to future sea level scenarios the continuation of the trend measured up to the present point. from the fact that the second sentence barely makes any sense, the authors provide nothing to support their claim that the models are incorrect; in fact most of what they say about models is demonstrably wrong. The two most obvious errors relating to models are indicated here.
