The Cosmic Microwave Background (CMB) temperature and polarization anisotropy measurements from the Planck mission have provided a strong confirmation of the Lambda Cold Dark Matter (LCDM) model of structure formation. However, there are a few interesting tensions with other cosmological probes that leave the door open to possible extensions to LCDM. I will review some interesting extended cosmological scenarios, in order to find a new concordance model that could explain and relieve tensions in current cosmological data.
