What is it about the Southern Hemisphere that makes its climate different from the Northern?
I suppose it is its location.

The Northern Hemisphere does.
Right. Note also that the Northern Hemisphere has a lot of land near and above the Arctic Circle, but the Southern Hemisphere has no land except Antarctica below the Antarctic Circle.
My improved answer: There are few subarctic climate zones in the southern hemisphere due to the absence of large land masses at the equivalent latitudes of the northern hemisphere.
Good.
