Consider this scenario:

As temperatures in high latitudes get colder, snow and ice accumulate

As snow and ice accumulate, more solar radiation is reflected

As more solar radiation is reflected, less energy is stored so temperature gets even colder

Is this an example of positive feedback, negative feedback or lack of feedback?

Expert Solution

Step 1

This scenario is an example of ice-albedo feedback. As temperatures in high latitudes decreases, it increases the accumulation of snow and ice. This accumulation increases the reflection of solar radiation. It leads to more cooling.
