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).
