Atop the world lies a thinning veil of ice. A gossamer lid covering a deep, dark Arctic Ocean. It is a reflector screen for incoming solar radiation during the months-long-day of Polar Summer. And a recent NASA study shows that this heat shield is starting to fail.

Ever since the late 1970s an Arctic warming at 2-3 times the rate of the rest of the globe has set off a 13.3 percent decline of sea ice at end summer during each and every following decade. And that cumulative loss is having an extraordinary impact. For the white, reflective ice cover by September has now, on average, fallen by nearly 50%. What remains is a thinner ice cover. One full of holes and interspersed with great and widening expanses of dark water.

Dark water and thinner, less contiguous, ice absorbs more of the sun’s heat. NASA notes that this added absorption…
