Read here. Paleo-climate and ocean scientists have relied on a theory to explain pre-historical, ancient and historical sea level changes. Now comes actual empirical evidence from the Mediterranean Sea that casts doubt on the "consensus" science.
Dorale et al. using precise measurement techniques determined that the Mediterranean sea level some 81,000 years ago was significantly higher than the current day level, which is counter to past accepted science.
"Precise measurements of sea level from Mediterranean caves have revealed that about 81,000 years ago the seas stood much higher than previously thought — even higher than today's levels.....now suggests that 81,000 years ago the sea level increased sharply to reach a high-point, roughly one metre above today's level. "At face value this is a very beautiful and solid piece of work," says Wallace Broecker, a geologist and climate scientist..."..."It suggests that, for reasons unknown, the sea level which at the time should have been down some 15 metres instead went up one metre, and then went right back down again within just a couple of thousand years."
