Why Do Forests Act Like Giant Air Conditioners?

Trees act like natural air conditioners. When they are hot, they sweat, not with water from a tap, but by letting moisture inside them escape into the air through their leaves. This is called transpiration. Just like when you sweat on a hot day and feel cooler, trees make the air around them feel cooler too. The more trees there are in an area, the more cooling happens, it’s like having many tiny fans working together to keep the whole place cool.
