Sea ice may have covered the Earth's surface all the way to the equator hundreds of millions of years ago, a new study finds, adding more evidence to the theory that a "snowball Earth" once existed.

Geologists found evidence that tropical areas were once covered by glaciers by examining ancient tropical rocks that are now found in remote northwestern Canada. These rocks have moved because the Earth's surface, and the rocks on it, are in constant motion, pushed around by the roiling currents of the planet's interior, a process called plate tectonics).

Okay, but it was also a tropical greenhouse where ferns grew to 50 feet tall. Which proves that there is no “normal” climate, just changing climate.
Thank God for global warming, else we would never exist.
