We investigate the correlation between the neutrino mass limit and dark energy with the time evolving equation of state. Parametrizing dark energy as w=w{sub 0}+w{sub 1}*z/(1+z), we make a global fit using Markov Chain Monte Carlo technique to determine w{sub 0}, w{sub 1}, neutrino mass as well as other cosmological parameters simultaneously. We pay particular attention to the correlation between neutrino mass {sigma}m{sub {nu}} and w{sub 1} using current cosmological observations as well as the future simulated data sets such as PLANCK, SNAP, and LAMOST.
