  A Fermi surface threaded by a Berry phase can be described by the
Wess-Zumino-Witten (WZW) term. After gauging, it produces a five-dimensional
Chern-Simons term in the action. We show how this Chern-Simons term captures
the essence of the Abelian, non-Abelian, and mixed gravitational anomalies in
describing both in- and off-equilibrium phenomena. In particular we derive a
novel contribution to the Chiral Vortical Effect that arises when a temperature
gradient is present. We also discuss the issue of universality of the anomalous
currents.
