Answer:
As a general rule, as the atmosphere gets warmer, it can hold more water vapor, and with more water vapor, we expect more clouds, and the increased clouds will then tend to limit the warming that initiated the increased clouds — thus we have another negative feedback mechanism.
Step-by-step explanation:
A feedback that increases an initial warming is called a "positive feedback." A feedback that reduces an initial warming is a "negative feedback." Clouds. Clouds have an enormous impact on Earth's climate, reflecting about one-third of the total amount of sunlight that hits Earth's atmosphere back into space.
