Slide 31 of this series.
Dr Salby analyzes the CO2 total versus ACO2, human emissions. What he finds is tha the lifetime is much less than that assumed by the IPCC. He also determines that the ratio of ACO2 to the total CO2 is a small number, meaning that human emissions in recent years is a small percentage of the CO2 in the atmosphere.
NEXT: We examine the ACO2 portion of the temp change for this century, the value of CS.
