From: Improved calculation of warming-equivalent emissions for short-lived climate pollutants
Cumulative methane emissions (1900–2100) from the historical period plus RCP 2.6 (solid), RCP 4.5 (dashed) and RCP 6 (dotted) converted to CO2-e emissions using GWP100 (cyan), GWP* using only the flow properties (orange), GWP* for both flow and stock properties using r = 0.75 and s = 0.25 (purple), against modelled warming response to the methane radiative forcing from the scenario database. TCRE values of 1.5 (shallowest gradient), 2.0, and 2.5 K per trillion tonnes Carbon equivalent (or 0.41, 0.55 and 0.68 K per trillion tonnes of CO2-we) are shown by grey lines
