Albedo feedback

Albedo feedback is a climate feedback involving changes in the Earth’s albedo. The minus signs on figure 2 indicate a negative correlation between elements of the cycle—the increase of one factor causes the decrease of another and vice versa. This figure shows that if surface temperature increases sea ice and snow pack formation will decrease. This leads to a decrease of albedo and accordingly an increase in surface temperature, setting the cycle into motion once again. It usually refers to changes in the cryosphere which has an albedo much larger (~0.8) than the average planetary albedo (~0.3). In a warming climate, it is anticipated that the cryosphere would shrink, the Earth’s overall albedo would decrease and more solar energy would be absorbed to warm the Earth still further.
