Today we review global climate modeling research that examined the contribution of the waste heat produced by buildings and vehicle emissions in very large cities. Although this heat is small compared to the warming from greenhouse gasses in the atmosphere for the entire world, the model simulations reveal large changes in the regional circulation near these cities which may intensify local weather events such as droughts or extreme storms.
