Cross-Section Box.2 Figure 1: Schematic of the AR6 framework for assessing future greenhouse gas emissions, climate change, 
risks, impacts and mitigation. Panel (a) The integrated framework encompasses socio-economic development and policy, emissions pathways 
and global surface temperature responses to the ﬁve scenarios considered by WGI (SSP1-1.9, SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5) and 
eight global mean temperature change categorisations (C1–C8) assessed by WGIII, and the WGII risk assessment. The dashed arrow indicates 
that the inﬂuence from impacts/risks to socio-economic changes is not yet considered in the scenarios assessed in the AR6. Emissions include 
GHGs, aerosols, and ozone precursors. CO2 emissions are shown as an example on the left. The assessed global surface temperature changes 
across the 21st century relative to 1850-1900 for the ﬁve GHG emissions scenarios are shown as an example in the centre. Very likely ranges 
are shown for SSP1-2.6 and SSP3-7.0. Projected temperature outcomes at 2100 relative to 1850-1900 are shown for C1 to C8 categories with 
median (line) and the combined very likely range across scenarios (bar). On the right, future risks due to increasing warming are represented by 
an example ‘burning ember’ ﬁgure (see 3.1.2 for the deﬁnition of RFC1). Panel (b) Description and relationship of scenarios considered across 
AR6 Working Group reports. Panel (c) Illustration of risk arising from the interaction of hazard (driven by changes in climatic impact-drivers) 
with vulnerability, exposure and response to climate change. {WGI TS1.4, Figure 4.11; WGII Figure 1.5, WGII Figure 14.8; WGIII Table SPM.2,
