The folks at National Geographic want a moment of your attention. They want you to absorb what's happening on our Arctic doorstep. To do that they've produced this GIF showing the decline in Arctic ice coverage over the astonishingly brief, 15-year period from 1999 to 2014.
What the graphic can't depict is that not only has the ice declined severely in area it has also greatly thinned. What once was thick ice is now thin ice. Yes, we're on thin ice - in several ways.
