  1. Note: statistics represent changes in 9-year smoothed HadCRUT anomalies relative to reference period of 1961 to 1990. TAS residual denotes the CO2_e-induced SAT. Trends of AMV-induced and PDV-induced SAT are calculated for global SAT anomalies that had contributions from AMV and PDV variations (shown in Fig. 3)
