The measurements of the Cosmic Microwave Background (CMB) have played a significant role in understanding the nature of dark energy. In this talk, we investigate the dynamics of the dark energy equation of state, utilizing high-precision CMB, BAO, and SNe-Ia data from multiple experiments. We examine the confrontation of several Dark Energy scenarios with contemporary data given that the 2024 Baryon Acoustic Oscillation (BAO) measurements released by DESI, when combined with the CMB data from Planck and different samples of type-Ia supernovae reveal a preference for Dynamical Dark Energy (DDE)
