The idea is that Earth’s climate went through a warming period just over 100,000 years ago, that was similar in many ways to the warming now. And the changes during that period were so catastrophic, they spawned massively powerful superstorms.
Now they blame seemingly identical natural change on man and want to tax you.

Researchers theorize that thousands of years ago, superstorms caused huge waves that hurled the huge rocks onto a Bahama island — and that it could happen again.
