虽然海冰大部分是白色，并反射太阳光线，但海水是深色的，并以更高的速度吸收太阳能。自近几十年来夏季北极海冰覆盖面积开始缩小以来，该地区反射率的下降实际上一直是科学家们关注的一个关键问题。随着更多的太阳能量被气候系统吸收，它加剧了该地区的持续变暖，这比地球上任何其他地方都要明显。
While sea ice is mostly white and reflects the sun's rays, ocean water is dark and absorbs the sun's energy at a higher rate. A decline in the region's albedo its reflectivity, in effect has been a key concern among scientists since the summer Arctic sea ice cover began shrinking in recent decades. As more of the sun's energy is absorbed by the climate system, it enhances ongoing warming in the region, which is more pronounced than anywhere else on the planet.
