Climate Science

Slide 34 in this series. 

 

Clouds are a key to climate.  Variation in global cloud cover is a high order variable in setting climate.  Clouds can cover 55 - 70+ % of the earth's surface.   High clouds are different than low clouds.   Clouds play a key role in reflecting energy from the sun and in releasing energy to outer space.   So in both cases they send energy out, having a net cooling effect.
