New emission scenarios
The Fourth Assessment Report was based on the own IPCC emission scenarios as developed in the Special Report on Emission Scenarios.
These emissions scenarios were used in climate model experiments, which
in turn were used to generate climate scenarios used in modeling of
impacts, adaptation, and vulnerability.
The development of scenarios for a possible Fifth Assessment Report of the IPCC will be undertaken by the scientific community. The IPCC will catalyze such work so as to promote its readiness in time for the 5th report cycle. Therefore, an IPCC Expert Meeting on New Scenarios will be held in the Netherlands, 19 -21 September 2007.
The objective of this meeting is to identify requirements and plans for development of new scenarios for research and assessment of emissions, climate change and response strategies. The scenarios will need to be of interest to the research and user communities, and will assist in the coordination of research assessed in a possible IPCC Fifth Assessment Report (AR5). The meeting will provide a unique forum for various groups and scientific communities to meet and discuss plans and coordination requirements for new scenario development. A Steering Committee will decide on the participants and the program of the Meeting.
