Crashing Plates and Big Ice

The Climate Has been Changing for Quite a While. 

ROCKIN’ AND ROLLIN’. We struggle to fully appreciate the impact of the shifting Tectonic Plates and the Ice Ages. They happened a really long time ago and the “to and fro” of massive ice sheets over hundreds of millions of years, combined with tectonic plate shifts, was the original “rock and roll” era; the land was formed, and reformed, with dramatic fluctuations in sea levels. 

CRASHING “PLATES”: The World Settles In. The shifting tectonic plate story is hard to fathom. Michael Grunwald tells the story as he describes the formation of the Everglades, “It began with a bang about 300 million years ago [MYA], after the fish but before the birds, with the cataclysmic shifts of tectonic plates that crunched the planet’s major landforms into a single supercontinent called Pangaea.”
