highlighting some of the challenges of comparing models with observations.

The World Climate Research Program (WCRP) workshops on sea ice predictability, which occurred in 2010 (WCRP, 2010) and in April 2012, brought together scientists from the modeling and observational sea ice communities. The aim of the workshops was the development of a draft implementation plan for a WCRP polar climate predictability initiative (WCRP, 2012).
