DENVER (KDVR) — New evidence recently uncovered in Colorado by researchers at the University of Colorado Boulder may prove the entire planet was completely covered in massive glaciers hundreds of millions of years ago.
The evidence is notable for people who believe in “Snowball Earth,” which is a theory that posits that from around 720 to 635 million years ago, the earth’s climate was drastically changed for reasons that are still unclear, according to a release.

This caused temperatures across the world to drop. According to this theory, ice sheets that could have been several miles thick covered the earth.
The findings were published in the Proceedings of the National Academy of Sciences. The lead author of the study was Liam Courtney-Davies, a postdoctoral researcher of geological sciences at CU Boulder.
Co-authors for the study include Rebecca Flowers, a professor of geological sciences at CU Boulder, and researchers from Colorado College, the University of California Santa Barbara and the University of California Berkeley.
