"Imagine a lake whose waters suddenly rise 15 centimeters a day. Envisage living in a village on a river terrace a short distance inland, watching an inexorable flood moving upstream as much as 1.6 kilometers daily. The inundation never pauses, just rises and rises, drowning crops, leaving only treetops emerging from the still, rising water. A red-brown muck from the water coats the green leaves, which soon vanish beneath the rising deluge. Canoes drawn up on the river bank float away. Within days, the flat river valley forms part of a growing, increasingly brackish sea.
One of the greatest natural disasters to affect humanity came in about 5600 B.C., when the rising waters of the Mediterranean flooded the deep basin of the Euxine Lake, 150 meters below the sea of Marmara, to form the balck sea"
Does this sound familiar to anyone?
