Evidence from Colorado suggests glaciers once covered Earth to the equator, supporting the Snowball Earth theory. This discovery provides insight into early climate shifts and the evolution of life.
Geologists have discovered compelling evidence in Colorado that hundreds of millions of years ago, enormous glaciers blanketed Earth as far as the equator, turning the planet into an icicle drifting through space.
The study, led by the University of Colorado Boulder, is a coup for proponents of a long-standing theory known as Snowball Earth. It posits that from about 720 to 635 million years ago, and for reasons that are still unclear, a runaway chain of events radically altered the planet’s climate. Temperatures plummeted, and ice sheets that may have been several miles thick crept over every inch of Earth’s surface…
