Figure 2
The time series of simulated globally averaged surface temperature. (a) Time series of globally averaged annual surface temperature anomalies for the period 1979–2005 from E1–3 (blue line) and GISTEMP (red line). (b) Same as (a), but for surface temperature from E4–6 (blue line) and GISTEMP (red line). (c) Same as (a), but for surface temperature from E1–3 (blue line) and HadCRUT4 (red line). (d) Same as (a), but for surface temperature from E4–6 (blue line) and HadCRUT4 (red line). The anomalies are obtained by removing the seasonal cycle and the time series are detrended. The correlation coefficients (r) between the two lines are shown in the top right corner and the “*” means r is significant at the 95% confidence level. The values in bracket are uncertainty range for the correlation coefficient at the 95% confidence level.
