Ice free arctic now predicted to occur no less than three separate times

Just a quick one, this. Yes, folks, it's another warble gloaming date for your diary, though this one is a little way off.
SEA ice in the Arctic is melting at a record pace this year, suggesting warming at the north pole is speeding up and a largely ice-free Arctic can be expected in summer months within 30 years.
[...]
Global warming has been melting Arctic sea ice for the past 30 years at a rate of about 3 per cent a decade on average. But the two new data sets suggest that, if these trends continue, a largely ice-free Arctic in summer months is likely within 30 years.
That is up to 40 years earlier than was anticipated in the last Intergovernmental Panel on Climate Change assessment report.
This prediction comes from the US National Snow and Ice Data Center, a body which I'm certain owes absolutely nothing to the large political and public concern, albeit dwindling in the latter case, about warble gloaming and would get exactly the same amount of government funding to the cent if nobody at all believed a word of it. If all the predictions I'm collecting come true it will be the third such ice-free arctic after the 'Gore ice-free arctic' of 2013 and the 'Hadrow ice-free arctic' of 2019. I haven't quite worked out how this latest ice-free arctic is four decades earlier than expectations of the same thing happening just two years from now and six years after that - perhaps ice travels in time if there's enough carbon dioxide above it. It might explain previous ice ages if much of our present day ice has travelled into the past, though I feel that we urgently need to find out if it's being replaced by water from then travelling forward. Just a matter of funding, further research is always needed.

Anyway, whatever the cause of time travelling ice the list of warble gloaming dates for our diaries can be updated to read:

So, er, do I need sunblock and my bathers for the rest of winter or what?

It's that ice travelling back in time from 2040, so it's still warble gloaming's fault. I can even prove it if I'm given enough money to research it. ;)
There is actually a video out on Youtube that is Innuit eskimo people being interviewed, one after another, who clearly state that the sun is no longer setting at the same location in the skies that it used to set (which others have been saying this in other parts of the world too), that the snow-drifts that form arrows pointing in the direction of the wind travel from west to east have shifted to pointing from south to north (or whatever the exact change in direction was, maybe not that precisely, I can't remember now) and that the sun is sitting higher up from the horizon line causing the sun's rays to hit more directly and for more time during the day, thus that there is more melting of the ice/snow in the northern areas around the pole. If this is their observation, which they state on the video interview, then it's less likely AGW as it is some repositioning of the earth on its axis tilting toward the sun. It's on Youtube, the video of Innuit eskimo people saying this is their observation.
Also a thought but for the northern polar region, that is mostly ice frozen in water - and frozen ice expands, where-as defrosted ice (water) contracts. Put an ice cube in water filled to the brim of a glass and after the ice cube melts, the water will recede from the brim going lower in the glass, not expand and overflow the glass. So this talk of melting ocean ice would actually make the water level recede, not increase.

Probably not a big effect to be seen in a glass of water, and of course there's a little thermal expansion of liquid water too. But certainly there's no doubt that the melting of floating ice does not mean increased sea levels no matter how many times idiot journos write crap like "Regional sea ice is retreating fast, threatening to raise global sea levels..." - I found a nice time lapse video for that blog showing that floating ice does nothing of the kind.
