|Description=In baseline scenarios, emissions and greenhouse gas concentrations increase substantially. The increase in emissions depends on socio-economic factors, such as population growth, economic growth, technology development and lifestyle. Most medium baseline scenarios in IMAGE result in a rise in global mean temperature of about 3 to 5 °C above pre-industrial levels by 2100 (Figure below). | |Description=In baseline scenarios, emissions and greenhouse gas concentrations increase substantially.

|Example=Policy interventions that affect future climate range from policy on energy and agricultural systems, air pollution measures, and land-use policies to direct management of radiative forcing. For instance, the IMAGE system can be used to analyse energy efficiency, use of low-carbon fuels, reduction in non-CO2 greenhouse gas emissions and reduction of deforestation ([[Overmars et al., accepted]]). Interventions related to policies on climate, air pollution and land use are described in Componens [[Climate policy]], [[Air pollution and energy policies]] and [[Land and biodiversity policies]], respectively. These measures lead to a change in emissions, and then to the expected reduction in radiative forcing and climate change. | |Example=Policy interventions that affect future climate range from policy on energy and agricultural systems, air pollution measures, and land-use policies to direct management of radiative forcing.

Short-term benefits in air quality and climate mitigation may be achieved by reducing black carbon emissions and ozone precursors. | * Mitigation in short-lived versus long-lived greenhouse gas emissions, and co-benefits with air pollution measures ([[Shindell et al., 2012]]).
