- I would split the subarctic in half length wise, with a north side and a south side.
- The reasoning for this is that fact that there is a large distance between the most northerly and most southerly areas of the subarctic. The distance is so much, that one area is significantly warmer than the other.
The fact there the latitudes vary so greatly, makes the data collected for this reason inaccurate since they have different variables.
Splitting it in an easterly and westerly fashion would also not work since the Hudson Bay is where the boundary would be drawn, but that large body of water still joins the two sides in similarities as it affects both sides.
