We have chosen to use the Millennium Ecosystem Assessment scenarios because of the spatially explicit and logically consistent forecasts of land-use change and GHG emissions embedded with them. However, the most recent GHG forecasts of the Intergovernmental Panel on Climate Change (IPCC) have changed somewhat. To give readers a sense of the assumptions underlying our scenarios, our four scenarios emissions pathways are shown next to the current IPCC scenarios (Fig. S2).
