---- quote from first article ---------------

"During certain intervals of Pliocene warmth, the sea level could have been as much as 75 feet higher than it is now," Scherer said.

"The rise in atmospheric carbon dioxide from burning fossil fuel has now elevated the concentration to 400 parts per million, matching for the first time the levels of the warm Pliocene," he added. "This makes the old debate about whether the ice sheet was notably smaller than it is now more relevant than ever."

Oh-oh. I'm at 36 feet elevation.

The major cities of Florida are all pretty low, except for Gainesville, which is in the nose-bleed altitute of 151 feet.
