Unfortunately we can't check the satellite images, because clouds brought in by low-pressure systems are blocking the view on practically the entire Siberian coast, but it looks like the Northern Sea Route is opening up for real.
Check the Uni Bremen sea ice concentration map:
I'd venture to say that this is rather early for the Northern Sea Route to be opening up. I believe it has opened up every year since 2007, but I don't have all the dates at my fingertips. Last year it opened up around August 18th.
This was to be expected as temperatures are still rather high in Siberia. As some bunny noted, yesterday's high temperature in Tiksi was 25C, and this NOAA temperature map shows temps in that part of Siberia being 5-10 degrees C above normal:
It's not just the air temperatures causing a lot of the in-situ melt. That huge expanse of open water in the Laptev Sea must have soaked up enormous quantities of solar energy as well:
Maybe the winds will blow some ice back in there, but I don't think there's enough thick ice around to plug that hole. The Northern Sea Route will be opener than ever before, or at least a very long time. If this is a recurring thing Russian icebreakers will soon be out of business.
