Geography?

I would work that over if I'd were you. You are not even getting into the maritime effect on the climate on land and the continental effect on the climate overall. I.e. mild and wet winters compared to cold and harsh winters. Cooler and wetter summers compared to hotter and more humid summers. The effect the ocean has due to the fact that water cools and warms slower than land mes. Keep plugging away my friend. This would totally be an F in my book.
