Answer:
c. favorable; positive
Explanation:
This process is referred to as the Ice-albedo feedback where any change in With global ice sheets, the global ice area will alter the albedo and the planets surface temperature. The ice reflects some of the some of the solar energy back to space resulting in cooler surface temperatures, however,the higher the altitude, the warmer the temperature resulting in melting of the ice sheets. This will cause a decrease in ice cover and the area is replaced by water or land - the albedo would then decrease
This feedback process is important in terms of management of global climate
