Alliance to Rescue Civilization - to protect the human species and its civilization from destruction via nuclear war, acts of terrorism, plague and asteroid collisions. Dedicated to creating continuously staffed facilities on the Moon and other locations away from Earth. These facilities will preserve backups of scientific and cultural achievements, and species, and reintroduce lost technology, art, history, crops, livestock and, if necessary, even human beings to the Earth, if need be.

Land has been acquired for this survival spot in Drakensberg. 2012 author Patrick Geryl is involved, and membership is available.

Overview of what it will take for humans as we know it to survive a cataclysm, with a focus on the number of people you will need in your survival party.

They don't all have a 2012 focus (lots are about Y2K...), but this is the best list to date.
