Figure 1. Changes in (a) mean temperature and (b) rainfall for the Amazon region (see fig. 1 of Huntingford et al. (2004) for precise region) from a perturbed physics ensemble of HadCM3 forced with historical and SRES A1B changes in greenhouse gases and other forcing agents. The changes in both (c) vegetation and (d ) soil carbon for the Amazon region are derived from the IMOGEN modelling system.
