doesnt prove much, the sea level 20000 yrs ago was 130 metres lower which equates a rise on average of 65 cm per 100 years . 19.5 cm sounds piddly and doesnt explain away the previous massive sea level rises.
then we have historical evidence of rising sea levels in roman times: As the sea level of the Mediterranean rose, the salt beds of Ostia and others, flooded and within a short period stopped producing salt. Vain attempts to move the beds inland met with difficulty in finding the vast flat areas needed for evaporation, combined with the requirement that the small sea tide would intermittently fill the pans. The port of Rome, Ostia, was moved inland at least three times, leaving historians with the evidence of this sea level rise. The archaeological evidence of this sea rise can also be seen at other port sites around the Mediterranean where at the original construction [at the height of the ancient Greek and Phoenician civilizations] is still submerged indicating that they were built when the sea level was still lower than the present day level ............. The Roman port of Ephesus [the quay] is presently more than 3m above sealevel. At a time when salt was almost impossible to produce at home at the traditional sites of Ostia, and Aquilea, supplies from the TATTA [Tuz Golu] salt lake in Central Anatolia were 'exported' through the 'salt' ports of Ephesus, Halicarnasus, Miletus, and others. Today with the sea level returned to a more modest 2m below the peak at approx. 400AD .....................
Catastrophic rise in the oceans eustatic sea level occured approximately between the years 40 BC to 100 AD. as a result of an abnormal changing world climate. One piece of evidence for this occurence was a sudden and abnormal riseof the Dead Sea level during this period, consisting of various morphological data, and dendrochronology. The Dead Scrolls were found at these high watermarks possibly stowed away as a protection from the rising sea, rather than the general theory that their owners were hiding from the Roman armies . It may also not be a coincidence that Ygal Yadin found in precisely the same caves, artifacts from another, pagan age two thousand years earlier, when a similar rise of the sea level is estimated to have occured.
