Global warming

7.2 Comparing modelled and observed temperature

The IPCC comparison between modelled and observed temperatures since the year 1860 is shown in the three charts below

Figure 2
Figure 2 Chart showing natural forcing
Figure 3
Figure 3 Chart showing anthropogenic forcing
Figure 4
Figure 4 Chart showing both natural and anthropogenic forcing

It is clear from these charts that both natural influences and anthropogenic forcing are required to explain the recent rises in temperature.
