  We obtain the reduced CMB data $\{l_A, R, z_*\}$ from WMAP9, WMAP9+BICEP2,
Planck+WP and Planck+WP+BICEP2 for the $\Lambda$CDM and $w$CDM models with or
without spatial curvature. We then use these reduced CMB data in combination
with low-redshift observations to put constraints on cosmological parameters.
We find that including BICEP2 results in a higher value of the Hubble constant
especially when the equation of state of dark energy and curvature are allowed
to vary. For the $\Lambda$CDM model with curvature, the estimate of the Hubble
constant with Planck+WP+Lensing is inconsistent with the one derived from
Planck+WP+BICEP at about 1.3 $\sigma$ confidence level.
