I'm given to unstandand the reason why the IOW and the rest of the south
coast for that matter is sinking is due to the fact that the highlands of
Scotland are still rising as a result of the "decompression" of the
subterrain from the relief of pressure from the last ice age. So like a
seesaw, the north of Britain is rising while the south of Britain is
sinking.

As there was me thinking it was because they ate more pies oop north.
