Impassable Northwest Passage Open For First Time In History

An anonymous reader writes "The Northwest Passage, a normally ice-locked shortcut between Europe and Asia, is now passable for the first time in recorded history reports the European Space Agency. Leif Toudal Pedersen from the Danish National Space Centre said in the article: 'We have seen the ice-covered area drop to just around 3 million sq km which is about 1 million sq km less than the previous minima of 2005 and 2006. There has been a reduction of the ice cover over the last 10 years of about 100 000 sq km per year on average, so a drop of 1 million sq km in just one year is extreme.'"

    That posting is the interesting, I useful fact to carry around.
    I'm still a global warming sceptic. I'm all for reducing carbon emissions and the like. I'm just not totally convinved the weather patterns and carbon emissions are intertwined as some of the figures look.

    Correlation is not causation.

    Nobody claimed that Amundsen has not done it back then. The claim is that the passage now is practicable in one go, because the whole passage is open. Amundsen needed several years to make it all the way through in bits and pieces. And he couldn't have done it in any larger ship than the one he used, due to the water water being as shallow as 3 feet. Not exactly an economically viable solution.

    If we wanted to do good things for the environment, we'd have an mostly-nuclear merchant shipping fleet by now.

    You are jesting, surely.

    If you had any idea about the condition of the merchant ships and the way their crews are hired, you would have never said that.

    Deep sea marine merchant fleets are governed by something which can only be described as a "law of the jungle", where the disposable crews (literally! I heard stories of men simply dumped in the next harbour, regardless of location, after losing arms or legs in accidents on the ship, without any concern about their means of medical care or transportation. Insurance? You gotta be kidding!) and rust-covered ships worked until they literally fall apart at sea, after which the owner simply collects more then their value, having shrewdly adjusted the insurance payout in anticipation. Any attempts at regulation usually result in the owners re-registering all of their ships in places in which bribery, corruption and non-existant regulation make up for an "ideal" merchant shipping home port. What did you think the words "flag of convenience" mean? Ever notice that all of those ships in the news which broke up on some rocks are flying weird flags from strange places, even though they are clearly owned by western conglomerates?

    Adding nuclear power to this mix would be truly suicidal.

    Consider a glacier. It is a big mass of ice running downhill. If it is relatively small and not on a very steep slope you can assume it is not moving and when it gets warm the main thing that is occuring is melting so the glacier retreats.

    Consider another glacier - a really big one with a lot of ice behind it and a large height difference and/or steep slopes. Something like this moves faster. When it gets warmer it will move faster again. These are the glaciers that are advancing.

    Unfortuantely we have people that really just want to win an argument that just take the amount of advance and retreat of a lot of glaciers and average it without considering why. They are completely ignoring the temperature measurements in those locations since they are pretending to use a glacier as a thermometer instead of the real thermometers that may actually be there.

    As for the warm is good argument - I recommend talking to a farmer. Whether it is a El Nino or La Nina effect in the Pacific in a paticular year is enough to drive farmers backrupt off the land in some areas - they know about warm weather in the wrong spot.
