  We compute the joint constraints on ten cosmological parameters from the
latest CMB measurements. The lack of a significant second acoustic peak in the
latest Boomerang and Maxima data favors models with more baryons than Big Bang
nucleosynthesis predicts, almost independently of what prior information is
included. The simplest flat inflation models with purely scalar scale-invariant
fluctuations prefer a baryon density 0.022 <h^2 Omega_b < 0.040 and a total
nonbaryonic (hot + cold) dark matter density 0.14 < h^2 Omega_dm < 0.32 at 95%
confidence, and allow reionization no earlier than z~30.
