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.


For the Greenland ice not to have any effect on sea level if it were to
melt, it has to be floating. So you are saying that Greenland is a 2000+
metre-high iceberg floating in the middle of an archipelago? That would mean
the ocean beneath the iceberg would be 18,000 metres deep. Almost twice the
depth of the Mariana Trench is going some!
