In Mary Papenfuss' article, Arctic Doomsday Seed Vault Gets Doused By Climate Change, she describes how the vault that was created to preserve seeds of the world's plants was flooded due to the rapid change in the climate due to climate change.  Papenfuss states that none of the seeds were harmed but the entrance to the vault was completely flooded due to the melting of permafrost.  Officials had chosen this location due to the fact that they believed that the permafrost in this location would not melt.  The Norwegian government, which owns the vault, and Statsbygg, the agency that runs the facility, both have stated that they will be keeping a closer eye on the vault and installing waterproofed walls to preserve the vault.
