The oldest-known sea wall, built an estimated 7,000 years ago, could not stop the Mediterranean.

This global thaw may have sped up the tectonic plate on which much of North America sits by up to 25 percent between 12,000 years and 6,000 years ago.

Mediterranean Sea dropped during the Messinian Salinity Crisis -- a major geological event that transformed the Mediterranean into a gigantic salt basin between 5.97 and 5.33 million years ago 2.

Between 15 million and 6 million years ago, a drop in ocean crust production may have lowered sea level by 26 to 32 meters.

More than 600 million people (around 10 percent of the world's population) live in coastal areas that are less than 10 meters (32 feet) above sea level.

Climate researchers thought that current global average sea levels were the highest in more than 100,000 years, but new models suggest oceans just 6000 years ago may have been higher than at the ...

Melbourne, the southernmost state capital of the Australian mainland, was established by Europeans a couple hundred years ago at the juncture of a great river and a wind-whipped bay. Port Phillip ...

Scientists have discovered ancient deposits in the Artà Cave on the island of Mallorca that suggest sea levels 3.5 to 4 million years ago were more than 50 feet higher than they are today.

A group of scientists studying evidence preserved in cave formations have found that sea level was as much as 52 feet higher than the present day more than 3 million years ago.
