Gillett et al. (2021) global warming attribution study Posted on 19 January 2021 by dana1981 A new study published in Nature Climate Change, Gillett et al. (2021), is the latest in a long line of 'detection and attribution' studies published over the past 20-plus years that have sought to quantify the factors responsible for the rise in average global surface temperatures. Gillett et al. used Detection and Attribution Model Intercomparison Project simulations from 13 Coupled Model Intercomparison Project Phase 6 (CMIP6) models. The authors note that the CMIP6 historical simulations "show very little net anthropogenic warming before the 1960s. This contrasts with the CMIP5 historical simulations, which showed on average approximately 0.2°C warming by the mid-twentieth century."
