Fig. 7 Time series of low-pass filtered globally-averaged land temperature anomalies, relative to the 1979-88 period, for the data (thick solid line), average of the 16 selected simulations (thin solid line) and its values plus and minus one standard deviation of the 16 simulations (dashed lines) in the upper panel, and the difference between the two curves in the bottom panel. The years on the abscissa are plotted for January of the particular year.
