There are persistent tensions in flat LCDM cosmology, most notably H0 and S8 tension. Modifications of the flat LCDM model designed to alleviate one tension typically exacerbate the other. Returning to basics, I will argue why evolution of cosmological parameters with effective redshift is expected in LCDM cosmology. I will review observations supporting this claim.
