  Hunter and Brown try to demonstrate in their discussion of the long term tide
gauge data published in my previous paper that the sea levels are accelerating
when they are not. The sea levels are mostly oscillating and certainly not
positively accelerating at the present time. As shown in the graphs proposed
here after, having an understanding of the oscillatory behaviour of sea levels
and by using linear and parabolic fittings but not being selective in the time
window to consider, the tide gauge of Sydney exhibits clear multi decadal and
inter-annual periodicities but no detectable component of acceleration,
similarly to the many others tide gauges of the Pacific or the rest of the
world having enough quality and length. If all the long term tide gauges do not
exhibit any present accelerating pattern, possibly some simulations and
reconstructions may be wrong similarly to the selective assessment of the sea
level rise by fitting only the few years of data useful to support the positive
acceleration claim.
