Quizplus · Accepted Answer

Global albedo refers to the amount of sunlight reflected back into space from the Earth's surface. During times of cooler global climate when there was more land surface covered by ice, the global albedo was higher. This is because ice reflects more sunlight back into space than darker land and water surfaces, which absorb more sunlight and contribute to warming.
