If you want to go to the north pole, you need to go to Russia definitely. Most part of the country has severe climate.
As for me the most interestig country with such severa climate is Russia. After my Chuckotka visit with www.russiadiscovery.com/regions/chukotka/ I was so impressed, that promised myself to come there more and more.
