Shade can be an important piece of it, but evapotranspiration (evaporation through the leaves) is responsible for 7-10 degrees of cooling in a normal environment. In a hot dry place probably even more. I think this is one of those "if the whole area is green, you get great effects. But that doesn't mean planting a garden in the desert does the same thing."
