Glaciation events during the Neoproterozoic (524–1,000 million years ago) and Paleoproterozoic (1,600–2,500 million years ago) periods—events that spawned ice ages that persisted for millions of years at a time—may have seen glacier ice encircle the planet in a frosty planetary configuration known as a Snowball Earth. Whether the planet could have existed in such a state, however, is a matter of considerable debate.
