Anyone who bothers to do the research would know that it is the North Atlantic current that controls the worlds average temperature.
You start off with a ice age ,the ice starts to melt diluting the salt in the North Atlantic current that slows down the current.
The current slows down and eventually stops causing a new ice age before restarting to flow again due to the melted ice reforming again to help the salt volume rebuild.
