List of data provided
---------------------------------------------------
This dataset contains:
- Global mean climate feedbacks estimated in abrupt4xCO2 simulations of 29 CMIP5 models and 49 CMIP6 models, compared with those assessed in AR6. The radiative kernels represented are the following:
- Water vapour & lapse rate
- Surface albedo
- Cloud
- Biogeophysical and non-CO2 biogeochemical
- Net feedback
- Planck response
CMIP5 - light blue
CMIP6 - orange
This Assessment Report - red
Individual feedbacks for CMIP models are averaged across six radiative kernels as computed in Zelinka et al. (2020).
The white line, black box and vertical line indicate the mean, 66% and 90% ranges, respectively. The shading represents the probability distribution across the full range of GCM/ESM values and for the 2.5–97.5 percentile range of the AR6 normal distribution. The unit is W m–2 °C–1.
Feedbacks associated with biogeophysical and non-CO2 biogeochemical processes are assessed in AR6, but they are not explicitly estimated from general circulation models (GCMs)/Earth system models (ESMs) in CMIP5 and CMIP6.
Further details on data sources and processing are available in the chapter data table (Table 7.SM.14).
