  We derive upper limits on the sum of neutrino masses from an updated
combination of data from Cosmic Microwave Background experiments and Galaxy
Redshifts Surveys. The results are discussed in the context of three-flavor
neutrino mixing and compared with neutrino oscillation data, with upper limits
on the effective neutrino mass in Tritium beta decay from the Mainz and Troitsk
experiments and with the claimed lower bound on the effective Majorana neutrino
mass in neutrinoless double beta decay from the Heidelberg-Moscow experiment.
