We present results from simulated large sky coverage (100 sq. degrees) Sunyaev-Zeldovich effect (SZE) surveys using the cosmological adaptive mesh refinement N-body/hydro code Enzo. We have generated simulated Light Cones from a very large volume (512 h-1 Mpc on a side) with unprecedented dynamic range. A significant new result from this analysis is that roughly one-third of the SZE flux in the image comes from objects with M<5x1013 solar masses and filamentary structures made up of gas in the Warm Hot Intergalactic Medium (WHIM) phase. We predict that upcoming SZE instruments are the only near-term telescopes that will possibly be capable of detecting the WHIM in emission. In addition, we find that emission from poor groups and filaments will bias (high) cluster SZE flux measurements at the 7-10% level with telescopes such as Planck and SPT.
