BTW how will sea ice melting cause problems down here? It won't raise
the sea level. In fact rumour has it that een if Greenland's sheet is
removed most of that will have little effect too neither as most of
Greenland is an archipelago apparently.

What rubbish! Not true, in fact it is worse. If ice is removed from
Greenland, isostatic release means the underlying rock will rise slowly
and raise sea-level further.

Not if Greenland is a matrix of islands masquerading as a lump of
snow covered rock it ain't.

Besides which every glacier is already floating on the melt-water
beneath it. Which I imagine would tend to indemnify the soil below
that where it exists from absorbing what other lesser men may take to
be dry ground.

Isostatic rebound is just another supposition.

What makes mountains grow is tidal effects on the aquifers that cause
them in the first place. All the Himalayan stuff goes up in galleries
some 4 to 7 magnitudes at a time. And I suppose it can just as easily
go the other way. Nothing to do with iso fatso.

How high do strata levels rise in strip mines and mountainside
quarries? Such earth removal should have 3 or 4 times more rebound
than the removal of water, which -if it is pressed to any extent,
melts and flushes downhill.
