The SSPs (shared socioeconomic pathways), as defined by the Intergovernmental Panel on Climate Change, correspond to the increasing trajectories of atmospheric greenhouse gas (GHG) concentrations and characterize a range of warming in global climate from mild to extreme; for this study, 3 SSPs were used, categorized as strict (SSP1-2.6; lowest projected change), medium (SSP2-4.5), and unrestricted (SSP5-8.5; highest projected change) GHG emissions.
