The tundra is a biome on the Earth that covers approximately 20% of its land mass, and it is almost exclusively located in the Northern Hemisphere. It is an environment that helps in the regulation of the CO2 in the atmosphere, and it is one of the biggest natural CO2 sinks. The living organisms in the tundra, are using the CO2 for their needs, thus removing parts of it from the atmosphere, and when they die, because the tundra is cold, and the decomposition is very slow, most of the CO2 remains trapped, and doesn't go into the atmosphere.
Unfortunately, the global warming is slowly changing the tundra, and prolongs the summer periods, thus reducing the permafrost period of the year, so the decomposition of the living organisms is getting quicker, and also bigger percentage of the CO2 from them gets to the atmosphere.

Answer:
Two countries that do not border each other: Norway and Iceland.
Norway and Iceland are separated by hundreds of miles of open sea, however, the two countries are very similar, both in culture, language and geography.
Both countries have fjords, both countries are cold during most of the year, and both countries speak North Germanic languages that descend from Old Norse (the language of the Vikings). This is because Iceland was first settled by people from Norway and from the British Isles.
Two countries that do border each other: Slovakia and Hungary
Slovakia is mountainous because it is crossed by the Carpathian Mountains. Hungary is flat.
In Slovakia, the dominant language: Slovak, is a Slavic language closely related to Polish and Czech.
Hungarian, the national language of Hungary, is a Finno-Ugric language that is more or less related to Finnish (but the relation is not that close).
