AH Challenge: Dystopic Scandinavia

So Scandinavia (I use it as the broad term including Iceland, Norway, Denmark, Sweden and Finland; I don't want this to turn into a terminology debate) is pretty much seen as a great place to live IOTL, save for the weather. Danes are sometimes called 'the happiest people on Earth', Sweden is characterized as a socialist wonderland by some American intelligentsia, and Norway is just so cute.

So my question is, with a 20th Century POD, how can it not be that, even perhaps the worse place in Europe? I'm thinking Yugoslav War style. Is it possible? Also, it would be appreciated if it was done so without a Nazi-wank ;).

Just throwing that out there to people who know more than me.
 
The worst outcry from environmentalists and some scientists about a new ice age comes true. By the end of the twentieth century Scandinavia would be having practically year round winter and glaciers marching across the land.
The government may still be nice but the countries themselves would be nice arctic wastelands.
