    Implies that the ship moved at average 45 km/hr; is this plausible?

    That's about 24 knots per hour. A cruise ship will do about 20. The report for the LNG carrier did 11 to 16 knots.
    We have to be wary of projection distortion in regards to maps at those latitudes.

    My quick measure (on an old MS Streets & Trips, which is great circle aware between waypoints) estimates 3400 statue miles, which implies 21.8 mph or 18.9 knots. Web page says 20 knots in the Barents Sea, then only 11 to 16 knots after.

    So 'Christophe de Margerie' moved at plausible speeds but without slowing ever. Not necessarily the scent of fear; she is first in class of ice-breaking LNG transports and with something to prove.

    Camp Summit, Greenland is having a 'heat' wave, nearly -5C. Other parts are going through a late melt.

    Take a moment to reflect on not only what seems to be happening, but our diverse ways of observing, and commercial shipping responses. Compare to 1970s when current 'hot streak' began.

    We knew so much less then.

    In 1970 I was 20 years old and by the end of the year, a failed relationship left me depressed. Although I wasn't paying attention to earth studies, I had already read about Venus and CO{2} runaway. Regardless, today we get news about the Arctic from a Russian source:

    Interesting times we live in.

    I appreciate the utility for a continuous record but I prefer to see diversity of sources. As we've seen, no one country or people are immune from choosing ignorance over facts and data. But there are enough space qualified countries who remain curious about the earth we live on.

    I didn't see any reference to: Joint Polar Satellite System

    Source: Joint Polar Satellite System
    "JPSS-1—the first satellite in the JPSS series—is scheduled to launch November 10, 2017."

    ps. I had a network package to install a 'dark fiber' circuit to:
