About 90% of baryons in the universe have thus far escaped direct observation. This is known as the \it missing baryon problem. The Sunyaev Zel'dovich effect (SZ effect) has the potential to directly measure the state of the majority of these missing baryons. The next generation CMB experiments such as AMIBA will provide an unbiased sample of the intergalactic medium through the SZ effect. The existing and upcoming simulations and analytical studies provide a quantitative understanding of the SZ effect. All these make the SZ effect a powerful baryon probe. We present an overview of this probe from both phenomelogical and theoretical aspects.
