Haha, that would be an insane trip to get to it! The problem is that Svalbard is almost impossible to get to without a big ship or a plane as well, seeing as it's a remote island way north of mainland Norway.

Yeah, it is baffling to me as well. We all know the world is getting hotter, even without man-made changes, so this would have happened somewhere along the time anyway. I don't really get why they didn't plan better for this either :P

Well, it might not really have any uses if all of mankind disappears. I guess it's more used for a scenario where most of the humans disappear, but not all :)

Thanks for the comment, @openheart!
