1.We will have some form of Òoperational attributionÓ
capability
2.D&A
studies will routinely use information from large, multi-model ensembles (and
will make more intelligent use of this information)
3.Structural
uncertainties in observations will become an integral part of D&A
research
4.We will have formally identified anthropogenic
fingerprints
ÆAt sub-continental spatial scales
ÆIn variables more relevant to climate impacts
ÆIn plant and animal distributions and abundances
5.Fingerprinting will be feasible with increasingly
shorter (< 30-year) observational records
