How a Melting Arctic Changes Everything by Bloomberg Graphics

Scientists refer to the dramatic changes occurring in the arctic as “Arctic amplification.”
A small change snowballs, and Arctic conditions become much less Arctic, much more quickly—like compound interest. Those dramatic changes in temperatures, freezing-degree days, sea ice acres and soil thaw are presented with stunning photography and a tale about oil and economics, humanity and science, politics and borders and the emerging risk of an emboldened and growing Russian empire. The narrative features an animated map of the top of the world showing rapidly diminishing multi-year ice giving way to more seasonal, less permanent ice—and new shipping lanes and altered ocean chemistry.
