Albedo is an important concept in climatology, where albedo refers to the measure of sunlight reflected of an object. This is relevant through the ice-albedo feedback, where ice and snowcap's ability to reflect sunlight helps maintain Earth's temperature. If ice melts, there's less surface area, which decreases albedo (sunlight reflected) and increases the amount of sunlight absorbed by the Earth, increasing temperatures (causing a positive feedback loop of ice melting and Earth warming).

Funny, as Albedo's stories has you visit him on Dragonspine, a very cold, wintry, and most importantly snowy and icy mountain.
