Arctic sea ice rapidly shrinking now.
Near Siberia, abnormally warm this year, there's hardly any sea ice left. 
Not good.
Next to its low extent (the part of the Arctic seas with over 15% sea ice left), the average Arctic sea ice thickness is also very low now: roughly 40% below what it wasd in the 1990s. Graph: @ZLabe
And, as you'd expect, the sea ice situation in the Siberian Arctic is the worst. Extent crashing: way below that in any year so far.
Graph: @ZLabe, of course.

The only multi-year sea ice left in the Arctic Ocean now is north of Greenland, Canada, and East-Alaska. Nothing at all in the Siberian half. Very sad to see.

And the steep drop in Arctic sea ice extent continues.
Arctic sea ice way of track now.
Sea ice extent in the Laptev Sea, north of Siberia, falling like a stone after long periods of abnormally hot weather.
The lone path of (total) Arctic sea ice extent also clearly visible in @NSIDC data now. Lowest ever for the date, by a clear margin.
Sea ice extent* in the Arctic yesterday, compared to what it used to be on this date during 1981-2010 (median = orange lines). Disastrous, especially on the Siberian side.

*) extent = sea area with at least 15% ice cover.
The seven warm weeks that wiped out the Siberian Arctic sea ice:
And what happens in the Arctic doesn't stay in the Arctic. One example:

This year's crashing Arctic sea ice extent (blue line on the left), compared to the averages of 4 decades, and to 2012, which had the lowest September minimum so far.
It's already below what used to be the minimum extent in the 1980s and the 1990s.
It's already below what used to be the minimum extent in the 1980s and the 1990s.
This is what was left of Arctic sea ice yesterday. Not a lot, with 6-7 weeks of melting to go.
Note that quite a large part of the sea ice area had less than 50% ice cover.

And of course, now the Arctic seawater temperature starts to go up, to 4⁰C above normal in the Siberian Arctic.
