Cold water absorbs more carbon dioxide than warm water. Assume a mechanism (such as the Milankovitch Cycle) leads to global cooling. Sea surface temperatures will then begin to decrease. Subsequently, more carbon dioxide will be removed from the sky (as it will be absorbed in large quantities by the cold water). As a result, atmospheric temperatures will get cooler. This process is an example of .

Feedback.

Explanation:

Climate feedbacks can be defined as an effect that occurs when a loop takes place between the input and output of a system. There are two types of feedback- positive feedback and negative feedback. Feedbacks can either reduce or inflate effects of climate forcings.

In the given case, the process of absorption of carbon dioxide by cooler water is an example of feedback.

Therefore, feedback is the correct answer.
