In predicting future sea-level rise what is first of all needed is to
determine the 'climate' of the events responsible for sea level rise.
These include, but are not limited to, simple melting of land-based
ice, expansion of warming sea water, ice-sheet/glacier collapse. In
order to quantify the effects of each of these it is necessary to
predict their frequency and/or rate of occurrence and the range of
their effects. This is not a trivial task! Taking measurements of the
past combined effects of these causes and trying to fit them to some
statistical function and then extrapolating that far into the future is
not sound science. By trial and error it is possible to find a function
that appears to fit the data well and which give the prediction that
you would like to see!

I'd agree with all of that.

I once saw James May (of Top Gear fame) being interviewed about climate change, say, rather in opposition of climate change activists
"I put ice cubes in my glass, and when they melted the glass was no fuller."

The annoying thing is, he must have known what he was saying was totally misleading, but he was still happy to say it.
