Clouds provide both positive and negative feedback responses to warming. On one hand, higher cloud cover can reflect incoming sunlight and cool the Earth's surface, acting as a negative feedback. On the other hand, certain types of clouds, such as low-lying and thick clouds, can trap heat and contribute to warming, acting as a positive feedback. Therefore, the net impact of additional cloud cover on the Earth system depends on the specific type, altitude, and location of the clouds.
