This same map has been used in many different scenarios. Edgar Cayce rings a bell for some reason. And it is the same copy I have seen all over the internet linked to 2012. The same general areas are shaded in.
Here's a link

Here is the George Michael Scallion
Map.
According to the Scallion map, I will have new beach-front property. Unfortunately the one Bill posted will reveal me under water.
So either way, those general areas could go underwater. And since David Wilcock is the reincarnation of Edgar Cayce, why don't you ask him about this topic and have him draw us a new map?
My point is that these maps are similar. The floods could be caused by volcanic activity in the oceans or other natural climate changes.
