  Cosmological parameters are constrained by a wide variety of observations. We
examine the concordance diagram for modern measurements of the Hubble constant,
the shape parameter from large scale structure, the cluster baryon fraction,
and the age of the universe, all from non-CMB data. There is good agreement for
$H_0 = 73.24 \pm 0.38\;\mathrm{km}\,\mathrm{s}^{-1}\,\mathrm{Mpc}^{-1}$ and
$\Omega_m = 0.237 \pm 0.015$. This concordance value is indistinguishable from
the WMAP3 cosmology but is not consistent with that of Planck: there is a
tension in $\Omega_m$ as well as $H_0$. These tensions have emerged as
progressively higher multipoles have been incorporated into CMB fits. This
temporal evolution is suggestive of a systematic effect in the analysis of CMB
data at fine angular scales, and may be related to the observation of
unexpectedly massive galaxies at high redshift. These are overabundant relative
to $\Lambda$CDM predictions by an order of magnitude at $z > 7$. Such massive
objects are anomalous and could cause gravitational lensing of the surface of
last scattering in excess of the standard calculation made in CMB fits,
potentially skewing the best-fit cosmological parameters and contributing to
the Hubble tension.
