Answer:

The correct answer is:

D)both positive and negative feedback

Explanation:

Because in this case the feedback becomes a cycle or selfregulation of the system, since a positive feedback would help increasing temperature in the atmosphere as it enhances the current conditions of the system, while a negative feedback would decrease it. As they change through time it is possible to observe how the positive and negative feedback become a loop to keep an equilibrium.
