DESCRIPTION:By Paul F. Hoffman (Department of Earth\nand Planetary Sciences
 \, Harvard University). Dr. Hoffman's\ninterest in 'Snowball Earth' relate
 d studies originated in northern\nNamibia\, where he has worked annually s
 ince 1993. The Snowball\nEarth hypothesis says that the Earth's surface be
 came entirely or\nnearly entirely frozen at least once\, some time earlier
  than 650\nmillion years ago. The hypothesis remains controversial and is
 \nbeing debated under the auspices of the International Geoscience\nProgra
 mme (IGCP) Project 512: Neoproterozoic Ice Ages. There are a\nnumber of un
 answered questions\, including whether the Earth was a\nfull snowball\, or
  a 'slushball' with a thin equatorial band of open\n(or seasonally open) w
 ater.\nSponsored by Department of Earth and Planetary Sciences\,\nÂ鶹´«Ã½ÍøÕ¾ U

  Tomorrow. IMAGE: BBC\nFree\, everyone welcome. Seating is limited. No\nre
