What we do know is that Northern Africa was invaded by the Sea People who were probably Greeks forced to flee because of Climate Change. Perhaps we are witnessing similar events over the next 20 years of the dryer and colder weather in the north which compels many to flee to the south.
The next thing will be that those dam Norwegians are invading the Mediterranean again - and that they still sweat too much in the heat and still stink!
Anyway, this was an interesting read. (g)
