An increase in the amount of high altitude, thin clouds would
A) cool the planet in a process called cloud-albedo forcing.
B) warm the planet in a process called cloud-greenhouse forcing.
C) have no effect on the planet's temperature because insolation is constant.

Question

Quizplus · Accepted Answer

An increase in high altitude, thin clouds would lead to warming the planet because these clouds trap outgoing infrared radiation from the Earth's surface, leading to increased greenhouse effect. This process is called cloud-greenhouse forcing.
