The overall objecting of WP5 is an improved understanding of the evolution of the coupled Earth system decadal-centennial timescales through the use of Earth system models (ESMs) of different complexities. Specific objectives are:

1. Development of a system of linkages and traceability across the hierarchy of GreenCyclesII ESM components.
2. Assessment of the consequences of different levels of complexity for model behaviour.
3. Investigation of climate-land surface feedbacks with respect to fire, tropical deforestation, and land use change.
4. Incorporation of anthropogenic activities into Earth system models.
5. Quantification of uncertainties in future Earth system evolution to calendar year 2200 taking into account level of process understanding and socio-economic feedbacks.
