E N D
Terminology • Unchanged • GCMs – General Circulation Models • AR4 • SRES – Special Report on Emissions Scenarios • AR5 • SSPs – Shared Socioeconomic Pathways • RCPs – Representative Concentration Pathways • RAPs – Representative Agricultural Pathways
RCPs • RCP 2.6 is below anything from AR4 • RCP 6 is most similar to A1B • RCP 8.5 is higher than anything AR4
SSPs • SSP1 – Low Challenges • SSP2 – Intermediate Challenges, business as usual (med-med) • SSP3 – High Challenges • SSP4 – Adaptation Challenges Dominates • SSP5 – Mitigation Challenges Dominates
Combining SSPs with RCPs • SSPs are separated from emissions, but not all SSPs are compatible with all RCPs
