(Mt/Ag/EnSc/EnSt 404/504 - Global Change) Future Directions (for the AR5) Future Directions in Globally Coordinated Climate Change Research Primary Sources: IPCC Expert Meeting on New Scenarios + CMIP5 Plans
2
(Mt/Ag/EnSc/EnSt 404/504 - Global Change) Future Directions (for the AR5) New Scenarios “long-term” scenarios 2100 and ultimately 2300 “long-term” scenarios 2100 and ultimately 2300 - climate targets for avoiding risks - long term strategies for mitigation & adaptation Global scenarios for two time periods “near-term” scenarios 2035 “near-term” scenarios 2035 - potential for “prediction” - directly linked to policy planning
