1. There little evidence for 'acceleration' of
sea level WRT temperature. Plot SL and T and
the best fit is a straight line, suggesting
empirical support is for SL = aT+c not
dSL/dt=aT , the rate related relationship
where sea level rises faster when as it gets
hotter.

2. The SL stopped increasing mid century
just when temperature stopped increasing.
This suggest at most a 10 year lag is
justified by the data. Could it also be that
the current low rate of SL increase is
because temperature has stopped increasing?
So if temperature does not increase much
then SL may not increase much either.

3. The estimates of 1m are based on IPCC
projections which are running way too high.
Current warming after subtracting out PDO
are about 0.5C Century. Anyway, if IPCC
projections are high side, the is sea level
will be too.

So, the projections of ~1m are (in my opinion) still the best. (Papers by Grinsted, Jevrejeva, Rahmstorf, and Vermeer all agree on this).
