identify which variables and processes are critical to simulating a realistic ice cover, (b) determine the sources of climate model drift, and (c) guide decisions regarding high-priority model development needs and the expansion of models to include additional capabilities and variables of interest to stakeholders; and

•   Create a centralized information hub that facilitates the timely access to observational and modeling results and encourages sustained communication among stakeholders.

These strategies are offered as guidance toward facilitating a transformative change in (1) our understanding of Arctic sea ice predictability on seasonal to decadal timescales and (2) our collective ability to realize and effectively communicate useful predictive power. The rate of advancement in sea ice predictions will likely be determined by the extent to which the broad user, modeling, and observational communities can achieve a sustained, integrative approach to refining and implementing these and other strategies.
