english: Each cylinder is about 10 percent ancient air, a pristine time capsule of greenhouse gases -- carbon dioxide, methane, nitrous oxide -- all unchanged from the day that snow formed and first fell.
non_english: U svakom cilindru ima oko 10% drevnog vazduha. To je iskonska vremenska kapsula efekata staklene bašte: ugljen-dikosid, metan, azot-oksid - svi ti gasovi nisu se menjali od dana kada se taj sneg formirao i pao.
