"Snowball Earth" and Global Glaciation 716.5 Million Years Ago


March 2010

Sea Ice to the Equator

Geologists have found evidence that sea ice extended to the equator 716.5 million years ago, bringing new precision to a "snowball Earth" event long suspected to have taken place around that time.

Funded by the National Science Foundation (NSF) and led by scientists at Harvard University, the team reports on its work in the journal Science.


It is our attitude toward free thought and free expression that will determine our fate. There must be no limit on the range of temperate discussion, no limits on thought. No subject must be taboo. No censor must preside at our assemblies.

–William O. Douglas, U.S. Supreme Court Justice, 1952
