After this very sad episod, an appreciable global warming occurred. The curve "jumps" around 8500 BP, and this "Holocene warming" favours human settlements in the Sahara: then begins the so-called "Climatic Optimum", and due to ice melting, rhe sea level raises significantly (here the blue line indicates sea-level variations in metres).
