WCRP Workshop on ‘Attribution of multi-annual to decadal changes in the climate system’

The aim of this workshop on “Attribution of multi-annual to decadal changes in the climate system” is to document current research, identify challenges, and explore potential pathways towards building an operational capability to attribute multi-annual to decadal changes in the climate system on global-to-regional scales.

Key areas to be addressed include:

• To what extent is the observing system adequate for the task and how best to use the observations
• Approaches to assess the roles of internal variability and external factors including greenhouse gases, aerosols, solar variations, volcanic eruptions, ozone and land use.
• To what extent are models adequate for the task and how to account for model errors, including underestimated signals
• To what extent do responses to different forcings add linearly
• How to account for forcing uncertainties?
• Analysis of physical processes
• Linking large scale circulation to regional weather and climate hazards
• Steps needed to build an operational capability
