The Cloud Feedback Model Intercomparison Project (CFMIP) contribution to CMIP6. (2016, background): “…and Dufresne, 2005; Webb et al., 2006; Zelinka et al., 2013), (b) the role of cloud adjustments in climate sensitivity (e.g. Gregory and Webb, 2008; Andrews and Forster, 2008; Kamae and Watanabe, 2012; Zelinka et al., 2013), (c) the processes and mechanisms which are (and are not) implicated in…”
Climate change projections using the IPSL-CM5 Earth System Model: from CMIP3 to CMIP5 (2013, background): “As stated before, the definition of the forcing ∆Qt is not unequivocal and recent work shows that the decomposition of 837 the forcing in a fast and a slow part allows to better analyze and better understand the temperature and precipitation 838 responses to a CO2 forcing (Andrews and Forster, 2008;”
Contributions of Different Cloud Types to Feedbacks and Rapid Adjustments in CMIP5 (2012, background): “…cloud masking have been performed only within a given model (e.g., Colman and McAvaney 2011; Watanabe et al. 2012; Wyant et al. 2012), only for fixed sea surface temperature (SST) simulations with perturbed CO2 (e.g., Wyant et al. 2012), and/or only in slab ocean models (Andrews and Forster 2008).”
The vertical distribution of cloud feedback in coupled ocean‐atmosphere models (2011, background): “Others have argued that much of the uncertainty arises from rapid cloud adjustments that are a direct response of clouds to changes in carbon dioxide rather than to changes in surface temperature [Gregory and Webb, 2008; Andrews and Forster, 2008].”
Climate Feedbacks and Their Implications for Poleward Energy Flux Changes in a Warming Climate (2011, background): “Andrews and Forster (2008) and Colman and McAvaney (2011) found that such semidirect effects of CO2 impact the interpretation of cloud feedback more than other feedbacks.”
What caused Earths temperature variations during the last 800,000 years? Data-based evidences on radiative forcing and constraints on climate sensitivity (2009, background): “Further evidences for a dependency of the cloud feedback on climate come from the semi-direct effect of the CO2 cloud coupling (Andrews and Forster, 2008).”
Anthropogenic and Natural Radiative Forcing (2014, result): “This is consistent with an earlier study of six GCMs that found a substantial inter-model variation in the rapid tropospheric adjustment to CO2 using regression analysis in slab ocean models, though the ensemble mean adjustment was less than 5% (Andrews and Forster, 2008).”
Precipitation, radiative forcing and global temperature change (2010, background): “Changes in temperature are required as a physical mechanism to change DLH and DSH, as well as other possible factors such as changes in clouds [e.g., Gregory and Webb, 2008; Andrews and Forster, 2008].”
Origins of differences in climate sensitivity, forcing and feedback in climate models (2013, methodology): “Andrews and Forster (2008) drew similar conclusions, and highlighted the role of cloud masking effects (Soden et al. 2004) on the cloud adjustment term. More recently Colman and McAvaney (2011), Wyant et al. (in press) and Watanabe et al. (2011) have analysed cloud adjustments in individual models. ”
On the interpretation of inter-model spread in CMIP5 climate sensitivity estimates (2013, background): “Moreover, and unlike Andrews and Forster 652 (2008), the consideration of the adjustments to CO2 does not reduce the inter-model spread of feedbacks 653 amongst CMIP5 models.”
Time-Varying Climate Sensitivity from Regional Feedbacks (2012, background): “…then includes stratospheric adjustments as well as any semidirect, tropospheric adjustments occurring on time scales of days to weeks (Gregory and Webb 2008; Andrews and Forster 2008; Williams et al. 2008; Colman and McAvaney 2008; Andrews et al. 2012a; Webb et al. 2013); importantly, the…”
Cloud feedback mechanisms and their representation in global climate models (2017, unknown): “Rapid Adjustments The cloud-radiative changes that accompany CO2induced global warming partly result from a rapid adjustment of clouds to CO2 forcing and landsurface warming.(38,39) Because it is unrelated to the global-mean surface temperature increase, this rapid adjustment is treated as a forcing”
