SI 3. Non-CO2 forcing
The non-CO2 forcing assumption in DICE is substantially higher than in other scenarios that analyse CO2 (or greenhouse gas) emission pathways consistent with 2°C or 2.5°C warming. In figure SI 3 we show the non-CO2 forcing assumption in DICE 2016 R2 as well as our recalibrated version of DICE compared to the non-CO2 forcing in RCP 2.6 and 4.5 as presented in Meinshausen et al (2011).
