Detailed 
likelihood definitions are 
provided in SPM Box1.  
The five illustrative scenarios 
(SSPx-yy) considered by AR6 
WGI and the Illustrative 
(Mitigation) Pathways 
assessed in WGIII are 
aligned with the tempera-
ture categories and are 
indicated in a separate 
column. Global emission 
pathways contain regionally 
differentiated information. 
This assessment focuses on 
their global characteristics.
