Query: Can CMB Lensing Help Cosmic Shear Surveys?   Yes! Upcoming galaxy shear surveys have the potential to significantly
improve our understanding of dark energy and neutrino mass if lensing
systematics can be sufficiently controlled. The cross-correlations between the
weak lensing shear, galaxy number counts from a galaxy redshift survey, and the
CMB lensing convergence can be used to calibrate the shear multiplicative bias,
one of the most challenging systematics in lensing surveys. These
cross-correlations can significantly reduce the deleterious effects of the
uncertainties in multiplicative bias.
