Observed annual surface air temperature (SAT) anomalies and atmospheric equivalent CO2 (CO2_e) concentrations. Here, 12 sites are randomly selected with 6 land sites (left panels) and 6 ocean sites (right panels). Red and blue points denote annual mean and its 9-year smoothed of SAT change with CO2_e from 1880 to 2017, respectively
