The Greenland ice sheet collapsed 400,000 years ago causing worldwide sea levels to rise between 13 and 20 feet.
It’s happened before. And before that.
It will happen again. And after that.
Humans weren’t here last time it did.. maybe we won’t be the next time, either.
But if we are… we better work on finding some new land to live on for future generations of our families, who now inhabit the coastline of everywhere USA.
