Under baseline conditions, scenario drivers are assumed to develop either along the pathway considered the ‘best guess’ translation of current trends into the future, or multiple contrasting scenarios are considered to explore the range of plausible future trends. The first approach has been chosen for many studies, such as the OECD Environmental Outlook to 2050 ([[OECD, 2012]]), as starting point for policy interventions to improve the baseline outcomes within and across sectors and issues. The second approach recognises structural uncertainties in how the world may develop, and explores how such uncertainties would play out in a future range of outcomes. Multiple contrasting scenarios also serve to investigate how robust policy interventions play out under different future conditions. Examples of multiple baseline studies are the Special Report on Emissions Scenarios ([[IPCC, 2000]]) and the Millennium Ecosystem Assessment ([[MA, 2005]]). | Under baseline conditions, scenario drivers are assumed to develop either along the pathway considered the ‘best guess’ translation of current trends into the future, or multiple contrasting scenarios are considered to explore the range of plausible future trends.

Recently, the Shared Socioeconomic Pathways ({{AbbrTemplate|SSP}}s) have been developed to support climate change research by different research communities ([[Moss et al., 2010]]; [[Van Vuuren et al., 2012]]; [[Ebi et al., | Recently, the Shared Socioeconomic Pathways ({{AbbrTemplate|SSP}}s) have been developed to support climate change research by different research communities ([[Moss et al., 2010]]; [[Van Vuuren et al., 2012]]; [[Ebi et al., 2014a]]). See both Figures below. The qualitative narratives or storylines characterising alternative futures are important elements of the SSPs From there, assumptions are made about internally coherent sets of scenario drivers, and key model drivers, such as population and {{AbbrTemplate|GDP}} growth ([[IIASA, 2013]]) | ||
