Scientists think Earth may have undergone at least two extreme freeze events throughout its history, becoming a so-called “snowball Earth” with a surface covered by ice. What triggered these events is ...

Around 700 million years ago, Earth was a frozen, white sphere, its rocky surface buried kilometers under ice. Despite the barren landscape, the evolution of complex life in the oceans was about to ...

A Yale-led research team has picked a side in the “Snowball Earth” debate over the possible cause of planet-wide deep freeze events that occurred in the distant past. According to a new study, these ...

Asteroid impacts at key moments in the Earth's past could have set off global freezes that covered the entire planet in ice for thousands or even millions of years. This is the conclusion of a study ...
