The Snowball Earth
This website contains an informational paper by Paul Hoffman and Daniel Schragg at Harvard University. The paper describes many lines of evidence supporting a theory that the entire Earth was ice-covered 600-700 million years ago. Each glacial period lasted for millions of years and ended violently under extreme greenhouse conditions. These climate shocks triggered the evolution of multicellular animal life, and challenge long-held assumptions regarding the limits of global change. Users can rea
