This talk will focus on the second issue of the IPAM Workshop II: Numerical Hierarchies for Climate Modeling: Properties of numerical
schemes for unstructured grids. Many next-generation global climate models will rely on unstructured or less-structured grids to
discretize the the surface of the sphere. These grids are needed in order to avoid the scalability issues associated with
latitude-longitude grids or to allow for improved regional resolution over areas of interest. I will describe our work developing CAM-HOMME, a compatible/mimetic version of the (spectral) finite element method for CAM, the atmosphere component of the NCAR Community Climate System Model.
