We investigate the thermal effects on the sudden changes and freezing of thequantum and classical correlations of remote qubits in a cavity quantumelectrodynamics (CQED) network with losses. We find that the detrimental effectof the thermal reservoirs on the system can be compensated via an efficientcoupling of the fiber connecting the two cavities of the system. Furthermore,for certain initial conditions, we find a double sudden transitions in thedynamics of Bures geometrical quantum discord. The second transition tends todisappear at a critical temperature, hence freezing the discord. Finally, wediscuss some ideas of the experimental realization of the present proposal.
