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.

It is true that the bulk of CO2 emissions are from the Northern hemisphere. However, CO2 does distribute throughout the world to achieve a natural balance, and the data that I can find says that the Southern hemisphere only lags about 1 or 2 years behind. Since we are in about the second decade of warming, that would suggest that the Southern hemisphere would be 1 or 2 years behind in warming as well, which has not been the case.
