The centrality dependence of dynamic fluctuations of the transverse momentum and the net charge can signal the approach to local thermal equilibrium in nuclear collisions. I explore this signal by comparing transport-theory calculations to STAR and PHENIX data at a range of energies. In particular, I find that this model can describe PHENIX data on the dependence of fluctuations on the <i>pt</i> range in which they are measured.
