LSU scientist Huiming Bao, along with colleagues from UCLA and China, recently discovered some of the first atmospheric evidence in support of the “Snowball Earth” hypothesis. This theory suggests that Earth was entirely covered by ice during the Cryogenian period, which took place from about 790 to 630 million years ago. Their findings were reported in the May 22 issue of Nature.
