I will discuss the latest results on the emerging tension between cosmology and neutrino oscillation experiments. I will also talk about the S8 tension between CMB and low redshift probes of matter clustering, presenting results from the FLAMINGO suite of cosmological hydrodynamical simulations. In particular, I will argue that baryonic feedback processes are cosmologically coupled, which naturally leads to stronger feedback for cosmological models with suppressed structure formation, such as models with neutrinos or decaying dark matter.
