Actually, yes it does. There are multiple cycles that affect the Sun. Yes, the northern hemisphere gets the majority of Sunlight. So go figure.
All you are doing is arguing in a circle. The thermohaline circulation is in equilibrium, then, it isn't.
So the system works to bring itself back into equilibrium.
Your arguments have consisted of "the system is working go bring back equilibrium, that it was working to bring back.
You ignore the fact that the system WAS in equilibrium, then, some OUTSIDE force pushes it out of balance.
