That's not really very significant added ontop of of a 65 meter rise, is it?

Of course. I didn't dispute that

Practically all freshwater on the planet is bound in the polar icecaps.
Melting mountain glaciers and semi-permanent snows won't add a meter.

Will, of course, increade the amount of water in the hydrosphere. I'm
entirely sceptical as to the possibility that it may in a cenury or so add a
hundred-odd meters to world sea levels.

All these contain relatively little water.

I don't see how these'd much affect sea levels.

Well over 90% of the hydrosphere's water is already in the seas.

Anyways, a 65 meter rise would certainly be apolcalyptic enough - the
majority of the planet's major cities placed underwater and thousands of
millions of people displaced, and that before changed local climates at
higher attitudes are figured in.
