Which of the following is a 'negative feedback' mechanism in the climate system?
AIce-albedo feedback
BPermafrost carbon release
CIncreased cloud cover reflecting sunlight (high albedo clouds)
DWater vapor feedback
✓ Correct Answer: C — Increased cloud cover reflecting sunlight (high albedo clouds)
Negative feedback dampens the initial change. Increased temperature can lead to more clouds, which reflect sunlight and cool the surface.
