Evaluating global warming potentials with historical temperature
Listed in National Center for Atmospheric Research
Global Warming Potentials (GWPs) are evaluated with historical temperature by applying them to convert historical CHâ and NâO emissions to equivalent COâ emissions.
Description
Our GWP analysis is based on an inverse estimation using the Aggregated Carbon Cycle, Atmospheric Chemistry, and Climate Model (ACC2). We find that, for both CHâ and NâO, indices higher than the Kyoto GWPs (100-year time horizon) would reproduce better the historical temperature.
The CH4 GWP provides a best fit to the historical temperature when it is calculated with a time horizon of 44 years. However, the NâO GWP does not approximate well the historical temperature with any time horizon. We introduce a new exchange metric, TEMperature Proxy index (TEMP), that is defined so that it provides a best fit to the temperature projection of a given period.

By comparing GWPs and TEMPs, we find that the inability of the NâO GWP to reproduce the historical temperature is caused by the GWP calculation methodology in IPCC using simplifying assumptions for the background system dynamics and uncertain parameter estimations. Furthermore, our TEMP calculations demonstrate that indices have to be progressively updated upon the acquisition of new measurements and/or the advancement of our understanding of Earth system processes.
