I used to believe in global warming. It was clear that the temperature was rising all the way to early August. But then something happened and it has clearly been falling every single month since then, thus disproving science bitches. Sometimes science is a liar!

Best example is the endless "Arctic ice is melting" hysteria every summer just to see the ice return in winter. There is more ice coverage now than at the beginning of this data set in 2006.

No hockey stick here.

Gets a chart and doesn't recognize what the data entails. Just great. Also, so nice of you to just get the last years which cuts out the longer term trend.

The size of the ice cover also doesn't say anything about it's thickness. It's cold enough for it to freeze over again, but it's thickness, and thus the amount of water that's gotten frozen again, is diminishing almost every year. About 70% of the sea ice is now 1st year ice, meaning only around 30% of the ice had survived at least one summer.

here, have a look at this: http://polarportal.dk/en/sea-ice-and-icebergs/sea-ice-thickness-and-volume/

Check the monthly case, as it has the same timeframe as your data does, only showing where the ice is - and more crucially, how thick it is. You'll see that over the years, red and yellow (thick ice) make more and more way for green and blue (thinner ice). The result: same area of glaciation, but much thinner ice and thus much less volume. But more on this below.

As you can see, sea ice did go down when you extend the scale a bit further than just to 2006. Especially the minimums in Fall are going down. But how about the volume of the sea ice, not just it's extent?

See how much the volume of ice has gone down even though the area of icing has only shrunk slightly?
