A doomsday seed vault built to protect millions of food crops from climate change, wars and natural disasters opened today deep within an Arctic mountain in the remote Norwegian archipelago of Svalbard. "It is the Noah's Ark for securing biological diversity for future generations," Norway's Prime Minister Jens Stoltenberg, center left, said at the opening today. European Commission President Jose Manuel Barroso, center right, was among the guests at the ceremony.
