WebSnowball Earth Albedo Effect. 867 Words4 Pages. The initiation of a Snowball Earth, involves a cooling mechanism in which an increase in the Earth’s coverage of snow and ice occurs. As mentioned previously, an increase in ice and snow coverage would result in an increase in the reflected fraction of solar radiation known as albedo. The initiation of a snowball Earth event would involve some initial cooling mechanism, which would result in an increase in Earth's coverage of snow and ice. The increase in Earth's coverage of snow and ice would in turn increase Earth's albedo, which would result in positive feedback for cooling. If enough snow and ice accumulates, run-away cooling would result. This positive feedb…
WebThe Snowball Earth hypothesis proposes that, during one or more of Earth's icehouse climates, the planet's surface became entirely or nearly entirely frozen.It is believed that this occurred sometime before 650 myr (million years ago) during the Cryogenian period. Proponents of the hypothesis argue that it best explains sedimentary deposits that are … Web2 content required for Snowball Earth initiation to occur is reduced. The atmospheric CO 2 content at which Snowball Earth initiation occurs is thus increased by 50% in the 3-layer Winton model compared to the 0-layer Semtner model. Overall, these results show that while the sea-ice thickness limit plays only a minor role, a suf-
