On a hot summer day, if you go outside and touch some object that's in the sun, it's going to be extremely hot. Touch a leaf. It's not hot at all. It's because it's reflecting that light. In fact, the coolest place in a garden on a hot summer day is where? It's under a tree because all of that infrared light is being reflected off.
all plant matter reflects infrared light. You grab a plant out here in California where maybe it's 80 degrees, the leaf is not hot. Why does that happen? It's because it reflects infrared light.
