many possible triggering mechanisms could account for the beginning of a snowball earth, such as the eruption of a supervolcano, a reduction in the atmospheric concentration of greenhouse gases such as methane and/or carbon dioxide, changes in solar energy output, or perturbations of earth's orbit. regardless of the trigger, initial cooling results in an increase in the area of earth's surface covered by ice and snow, and the additional ice and snow reflects more solar energy back to space, further cooling earth and further increasing the area of earth's surface covered by ice and snow. this positive feedback loop could eventually produce a frozen equator as cold as modern antarctica.
