Quoting Daiwa, reply 1607And Ephesus was a bustling seaport then - thanks to subsequent cooling it's now ~5 miles from any water.
That's because of tectonics... the land is pushed up by the African continent.
The sea levels today are about 2 meters higher than they were back during he Roman times.
Also, no reputable source is claiming sea levels are going to rise, AGW or no, a meter in the next century. the sea level has been rising about a couple mm a year since the last ice age ended And it has been a very steady rise at that.
This is another reason AGW proponents are so frustrating. They don't know the science. They don't read the IPCC reports. They watch An Inconvenient Truth and think they know something. There is zero evidence that fossil fuels are the cause. That's because CO2 is unlikely to be a significant driver of temperatures one way or the other. It's a weak green house gas making up 0.4% of the atmosphere.
Humans instinctively wish, dream we had control over the weather. It's not new. We used to blame witches. Now we blame oils and coal. Not that people truly believe it because they aren't willing to personally do anything about it.
