Comparison between urban and rural stations appears to lead to an underestimate of the strength of the urbanization influence. A detection and attribution formalism allows decomposition of China's temperature record into externally forced, urbanization induced and internal variability induced components of change Results suggest about 1/3rd of the recorded warming is due to urbanization Anthropogenic and natural external forcing combined are estimated to have caused 0.93°C [0.61-1.24], consistent with the observed global land mean warming 1.09°C [0.86-1.31enUN SDG 13: Climate ActionPresentation
