As I pointed out, dramatic shrinking of the thicker sea ice has occurred over the past few years. I've meanwhile also added images by Harold Hensel and Paul Beckwith, which may shed further light on this. Indeed, apparent discrepancies may be due to the way volume is calculated and I look forward to some further discussion on this.

Add tensions with North Korea and the Great 'rotten' Pumpkin. All this winning.

I'm still working on further content for this post. Point is that it's raining over the Arctic Ocean, which can devastate the sea ice. I'll add more on this soon.
