Have you noticed that your evidence of that is complete crap? Photos of open ocean? You actually want to put that forward as evidence?
The baseline average in that plot covers 30 years, includes almost ALL available satellite data and includes the oldest of the traces.
But you've got a picture of open ocean somewhere.
Right.
No kidding? Really? And did you know that by the definition of average, if extents aren't shrinking, the odds of five in a row being on one side of mean is 1/2e5 or 0.03125:1
Have you noticed that your baseline covers a pitifully small period of time...have you also noticed that historical documents from people who have sailed those waters, and historical news makes it clear that in the early 20th century, there was considerably less ice than now?

Where the hell did you get that factoid? You evidently didn't read or understand the constrainsts for that evaluation.. Hint --- it's NOT an independent random draw.
Show us some convincing evidence that Arctic ice extents were at current levels or lower BEFORE 1910.
Have you noticed this?

I think you've gotten a little confused, as I'm posting charts to show ice extent is higher in the past.
Charts go back to 1896, so here's June 1901. Compared to June 2014, ice extent is much bigger in 1901. Much more ice in the Greenland Sea and around Svalbard, and no melt at all off Siberia.

And no one but AGW deniers has posted in your thread in weeks. It is nothing but an echo chamber. I personally think management ought to delete it. There's no "discussion" taking place there.

The actual historical records from the Danish over that period show much more ice than we have now. For example, this chart of August 1932 shows an ice extent very similar to June 2014, two months earlier in the melt season. The Danish charts are by far the best historical data available, and they flat out contradict you, hence you'll find a reason to handwave it all away in favor of a newspaper clipping.

Look what a large portion of the extent readings are below the baseline average.

With the exception of about ten days in 2012, the extents values during these five months, haven't gone above the baseline average in five years.
