Overview of WGCM (G. Meehl, S. Bony)

WGCM and AIMES meeting summaries
Recap WGCM discussions about CMIP6 (G. Meehl, S. Bony and WGCM)

Reflections on the RCPs process (R. Moss)
Comments on CMIP5/6 based on the RCPs from the viewpoints of IAM/IAV community (K. Takahashi)

CCMI (V. Eyring)
What has C4MIP learned from CMIP5 Lessons for CMIP6 (P. Friedlingstein)
C4MIP experiments: AIMES perspective (V. Brovkin)

Science questions for CMIP6
How can we reduce the range of projections?
How can we encourage model evaluation and improvement before scenario runs?
Which new feedbacks will be included for CMIP6, and which WGCM and AIMES activities are required to support these? Are new datasets required?
Can we begin to answer questions on the likelihood of climate “tipping points”?
What questions do we want to address with scenarios?
How do we ensure a balance between scenarios that have scientific relevance and scenarios that have policy relevance?
How different should the scenarios be to provide different climate responses?
How different should the scenarios be to provide different socio-economic responses?
How much can we understand the climate responses to scenarios based on pattern scaling?
How can we make the most of emergent constraints?
Others to be collected from discussions through the day…..

Towards CMIP6
Suggestions of coordinated experiments
Connections to analysis
Opportunity for a scenario-MIP?
SSP/RCP matrix: questions, sampling strategy, etc

Next steps
Scope and outline of the pattern scaling workshop
Actions for WGCM and AIMES.
