As global temperatures decrease, ice cover increases causing higher albedo which causes temperature to continue to drop is an example of positive mechanism.
<h3>What is Ice Albedo?</h3>
A significant component of global climate change is ice-albedo feedback. Surface albedo falls in the polar zone as snow and ice area declines, and the intensified solar heating further reduces the snow and ice area.
A positive feedback loop is exemplified by the ice-albedo feedback. A feedback loop is a cycle within a system that alters the impact on it, either positively or negatively.
Therefore if ice cover increases then the global warming is decreases as climatic conditions changes. It is a positive feedback.
