Fig. 4. Long-term (after 300 years) responses of surface temperature and precipitation to CO₂ increase.

(A, C, and E ) Results of annual mean temperature (shading in °C): (A) the CTLCO₂ minus the CTL (C) the ADJCO₂ minus the ADJ, and (E) the difference between (C) and (A). (B, D, and F) Similar to (A), (C), and (E) but for the results of annual mean precipitation (shading in mm day⁻¹).
