Great quiz. Does make me wonder if this is somewhat of a failing of the Koppen climate system. It seems to not differentiate much between more continental tundra climates found near the poles, and the tundra climates found here, which by and large are classified as tundra as they have a very stable, and cool temperature below the cutoff for a tundra climate, but cannot achieve the extreme colds that are seen in polar or temperate regions with tundra climates.
