   Noone really knows, but astronomical parameters are probably the main   
   cause. Feedbacks follow a cause, temperatures variations precede CO2   
   variations. Natural systems must have a large stability margin around   
   their current state. Systems with positive feedbacks are inherently   
   instable or at the brink of instability (which is visible).
