Quizplus · Accepted Answer

Clouds have a net cooling effect on climate because they reflect incoming solar radiation back into space, reducing the amount of sunlight that reaches the Earth's surface. They also absorb and re-emit thermal radiation from the Earth's surface, trapping some of the heat and warming the atmosphere. However, on balance, the cooling effect outweighs the warming effect.
