If one postulates that the global average surface temperature tracks the CO2 concentration in the atmosphere, possibly with some delay, then when the CO2 concentration continues to rise monotonically but the global average surface temperature shows fluctuations as a function of time with changes in slope (periods wherein it decreases), then you must throw the postulate away.
