However, a clear understanding of how national emissions reductions commitments affect global climate change impacts requires an understanding of complex relationships between atmospheric ghg concentrations, likely global temperature changes in response to ghg atmospheric concentrations, rates of ghg emissions reductions over time and all of this requires making assumptions about how much CO2 from emissions will remain in the atmosphere, how sensitive the global climate change is to atmospheric ghg concentrations, and when the international community begins to get on a serious emissions reduction pathway guided by equity considerations.
