Common scenarios

Scenarios provide insight into… socio-economic and development in

order to determine mitigation effort and

cost-benefits of climate change

Scenario provide insight into… plausible development of forcers and plausible climate futures

Scenarios provide insight into… socio-economic

development (vulnerability) and

climate change (impacts)

Scenarios play a key role in climate research

Scenario matrix architecture forms scenario tool kit

• Offers storylines and quantitative information for ‘reference scenarios’ for: • Further elaboration in impact research (consistent

set of socio-economic data) • Basis for new climate research (e.g. treatment of

land-use, aerosols) • Offers opportunity to elaborate scenarios in

regional/sectoral studies • Provides opportunity for mitigation ánd

impact/adaption research in one structure

Mitigation Impacts/adaptation

Feasibility and costs of targets greatly depend on the SSP
