Northern Hemisphere's
The Mollwiede projection of Earth shows that there is more landmass in the Northern Hemisphere than in the Southern Hemisphere. While perhaps not obvious just at a glance, the Northern Hemisphere's surface is about 40% landmass and is covered by about 60% water in the Northern Hemisphere
And how will it affect climate?
Well we know that warm water currents cause hurricanes.... storms and all that mumbo jumbo... taking this into consideration
We arrive at the conclusion that if there is a larger body of water present you will have a slightly bigger chance of warm currents.... more tsunamis and all that
