Seeds from more than 200,000 crops are on their way to an underground vault in Longyearbyen, where they will, in theory, be safe for post-doomsday stragglers to use as they rebuild.
According to last year's news release about the project:
Svalbard’s airport is the northernmost point in the world to be serviced by scheduled flights – usually one a day. For nearly four months a year the islands are wrapped in total darkness.
The site was chosen, in part, because the ground is perpetually frozen, providing natural back-up refrigeration that would preserve the seeds should electricity fail. Yet, even here, project architects had to consider how to offset the potential impacts of climate change.
The design will accommodate even worst-case scenarios of global warming in two main ways. For one, the vault will be located high above any possible rise in sea level caused by global warming. The vault will be located some 130 meters (426 feet) above current sea level, ensuring that it will not be flooded.
