noah didnt fiddle with greenhouse gases

An article in todays paper reports on how flooding due to the melting of the North American ice sheet 8300 years ago resulted in displaced populations opening up Europe for agriculture. They believe that the flooding occurred over about 34 years.
If this is true, then all the alarmists that are telling us that the current trend is all man made and can be slowed down or reversed better make sure they have got it right, because if they haven't and we are lulled into a false sense of security that disaster can be avoided, they will have led us all into an even bigger disaster.
