Do they want to know how they contribute to Arctic warming? Not in the least!
Concerning the Arctic warming all are very proud. Some climate change expert claim that global warming may reduce sea ice in the Arctic Ocean to insignificance pretty soon. Off-shore industry sees advantage to move sea-bed explorations quickly further north. Merchant shipping watches with interest the vastly decreasing sea ice extent. And here we are! A Russian liquid gas tanker (LNG) “Christophe de Margerie” just set two Arctic records few weeks ago (Details). The ship not only traveled through the Arctic in record time, but has done so without the use of an icebreaker escort. She is the first of a total of 15 planned LNG carriers that will be gradually deployed.
That is a horrible aspect. At least it is not known which alterations shipping, naval forces, research vessels and off-shore industry cause ins the Arctic Ocean sea-body structure, whether ice covered or not, and the subsequent impact on the annual sea ice and the polar-weather, called climate change. Bad that science has no idea about this human Arctic warming aspect. Worse, science has never rose, or ever been willing to raise and investigate the subject. At least you will face a hard time to find anything in this respect.
When considering the possible impact of ocean uses on climate change, any activities at sea north of the Polar Circle is a multifold higher than in any other Ocean region. Between the Arctic Ocean and the Equator the climatic impact of human activities the difference could be several hundred, if not thousand times, due to extreme narrow structure margin concerning water temperature and salinity. The temperature range in the upper 150 meter sea surface level is minus 2° to plus 4°C. Arctic salinity is down to 30ppt in places, while the oceans vary between 34ppt and 36ppt. So far it is statistics, and they are ‘wrong’ if not properly applied.
What the statistics do not show is the huge difference between the season, and the tremendous difference between a complete sea-ice cover, broken sea ice and open sea. The statistics show no difference between the freezing and melting period, both can extent over a half year. In the former case the immediate sea water level raises salinity significantly, instandly causing (as heavier water) a strong vertical current. During the melting, the surface layer is suddenly almost free of salinity, and because this water is much lighter than salty water, forms a stable and some meters deep water level, particularly as long as the sea ice remains intact. That may last for many weeks, or up to a few months.
Navigating and other ocean uses in Arctic sea areas without knowing the impact is irresponsible. Navigating through compact ice is even worse, as the force of ship screws may travel over long distances, with significant changes to sea temperatures and salinity. But science does not care. For decades they send research vessels deep into the Arctic region. No wonder that the off-shore industry and shipping does not care either. But that has to change. Any LNG-, cruise-, research-vessel or other uses in the Arctic region should immediately be investigated of having a serious impact on Arctic warming and subsequently climate change.
