If a change in surface properties leads to a net increase in warming by reducing overall reflectivity, what type of climate feedback is this considered?

Answer

A positive feedback

When surface changes cause more warming—such as when ice melt reduces reflectivity—this mechanism within the climate system is termed a positive feedback.
