This is actually one argument for man made global warming. Almost all of the world's industry and CO2 emissions are in the Northern hemisphere.
I was taught years ago from a science teacher that the weather patterns between the North and South do not mix, they stay rather separate. This tidbit was brought about during a discussion on a nuclear winter. They estimate that after a nuclear war, the Southern hemisphere would not receive much change, assuming no/minimal use of nuclear weapons in the southern hemisphere.
