Roughly a thousand years before the Sahara became incompatible with humans, an area the size of England sank beneath the waves. Humans lived there. We have evidence of that (as we do of pre-desert Sahara). Another big chunk of fertile human habitat that was there in the past and gone in the present. It sure as hell ‘aint a sunk just few millimeters in depth.
…I think of this sometime when people are publicly emoting over changes in a glacier…
How much CO2 was humanity responsible for then?
