Mourners in Iceland gathered Sunday to bid a final farewell to 700-year-old Okjokull, the first Icelandic glacier lost to climate change.

Part of this snow, which is not dissolved during summer, impregnated with rain and snow-water, is frozen during winter, and forms that opaque and porous ice of which the Lower Glaciers are composed.
