Fig. 7. Reconstructing Earth's recent climate.

(A) Observed monthly mean global temperatures (black) and an empirical model (orange) that combines four different influences. (B) Individual contributions of these influences, namely El Niño–Southern Oscillation (purple), volcanic aerosols (blue), solar irradiance (green), and anthropogenic effects (red). Together the four influences explain 76% (r2) of the variance in the global temperature observations.
