FIG. 49.7 Two models for observed changes in mean global temperature over the past century. The model that incorporates both human and natural inputs (pink) closely matches the observed record (black), but the model based only on natural inputs (blue) does not. Data from Meehl et al. (2004) Journal of Climate 17: 3721-3727, Fig. 2d.
