  In this paper I examine how well Ryskin's model of emergent cosmic
acceleration fits several sets of cosmological observations. I find that while
Ryskin's model is somewhat compatible with the standard model of cosmological
acceleration ($\Lambda$CDM) for low redshift (z < 1) measurements, its
predictions diverge considerably from those of the standard model for
measurements made at high redshift (for which z > 1), and it is therefore not a
compelling substitute for the standard model.
