On the western coast of South America there are remains of sea faring people’ at about 300 feet higher than today’s sea level. Yes, that coast is rising, but it is also indicative of much higher sea levels in the past 15-20,000 years.
For everything there is a season.....
On the history channel there was a show on Roman history and they featured a major Roman port, now a mile or so from the sea shore.
As someone else pointed out, the coast line is not fixed. It changes for a variety of reasons. I am 100% sure if the ocean level was rising one inch every 100 years (or what ever amount the socialist claim)we would have time to get out the way.
This whole we have to change society to prevent global warming/cooling/or staying the same is insane, yet people believe it. It is almost a religion for them. I think they are going to be suicidal when it does not occur.
