The greenhouse effect is when the temperature rises because the sun's heat and
Light is trapped in the earth's atmosphere. This is like when heat is trapped in car. On a very hot day,the car gets hotter when it is out in the parking lot. This is becuase the heat and light from the sun car get into the car, by going through the windows , but it can't get back out. This is what greenhouse effect does to the earth. The heat and light can get through the atmosphere ,but it can't get out. As a result , the temperature rises. Sometimes the temperature can change in a way the helps us.
