Photo by @kiliiiyuyan // A bright spot in an overcast sky over the Beaufort Sea is a clue. The clouds there appear brighter because a large patch of sea ice is beneath, reflecting the light of the sun. This same phenomenon is one of the reasons losing sea ice is a downward spiral— the ice, being white reflects an enormous amount of the sun’s rays back through the atmosphere instead of absorbing them. As the sea ice goes, the oceans warm, and so does our planet. Follow me, @kiliiiyuyan, for more from the Arctic and beyond. #seaice #arctic #alaska #climatechange
