"Post Apocalyptic" Search Trends on Google - Does Scandinavia love the end of the world?

I just a quick lookup of the term 'Post Apocalyptic' on Google Trends - the term certainly has been on the increase the past couple of years:




What I find interesting is the term is especially highly used for Scandinavian countries - perhaps they feel that Ragnarök is approaching? Perhaps it has something to do with extremity of the poles - Canada rounds up the northern half  as well as a couple of down-under countries, Australia and New Zealand.
