Where is it?
Subrctic Regions of the World
Just below the Arctic and above the temperate deciduous forest/deserts, The Subarctic is located in North America, North Europe, and Most of Russia. The Subarctic climate is only found in the North Hemisphere because there is no large landmass at the same latitude in the southern hemisphere. Not much people lived here because of its very harsh and bitter winter, but people do vacation there in the warm, mild summers.
How?

Millions and Billions years ago, The earth looked like the picture. Then the Arctic and Subarctic looked like it was in the same place. However, there was also was an Arctic and Subarctic to the south. As time moved on and continental drift took its place. In present time, the landmasses moved and is still moving and soon, due to global warming, the Subarctic is in danger of disappearing.
