This reduction may be ascribed to the changing state of the Greenland snow cover and glacier surfaces rather than to a decrease of the effective area that they cover (Box et al., 2012; Tedesco et al., 2016 ). signs that jesus is returning

"WebAlbedo effect. Albedo is the ability of a surface to reflect sunlight (solar radiation). Snow and ice have high albedo – much of the sunlight hitting surfaces covered with snow and ice bounces back. In contrast, dark earthy surfaces have a low albedo, therefore, they absorb more sunlight. Thus, the proportion of Earth’s surface that is ... " - Snow albedo effect
