Dr Arnd Bernaerts has long studied effects in Northern European Seas. Here are excerpts from his recent publication: Offshore Wind-Parks and Northern Europe’s Mild Winters: Contribution from Ships, Fishery, et cetera? http://www.davidpublisher.org/Public/uploads/Contribute/569da5d061f90.pdf
His main point from the abstract: The marine environment of North Sea and Baltic is one of the most heavily strained by numerous human activities. Simultaneously water and air temperatures increase more than elsewhere in Europe and globally, which cannot be explained with “global warming”.
Since mankind, during the course of a year, agitates the water column of North Sea and Baltic by stirring, more warmth is taken to deeper water in the summer season and rises to the surface from lower layers in the winter period, where heat is exchanged with the air until sea icing is observed. This is a process that can be seen from the beginning of September until the end of March.
Marine activities play a much bigger role in time factor and duration of ice formation. If the sea surface temperature has already reached the freezing point, any vessel shovels warmer water to the surface, or vice versa, forcing a more rapid melt… The shrinking ice cover correlates well with an increase in human activities, and subsequently leading to higher air temperature throughout the region.
Basically three facts are established: higher warming, a small shift in the seasons, and a decreasing sea ice cover. In each scenario the two seas’ conditions play a decisive role (North Sea and Baltic). These conditions are impaired by wind farms, shipping, fishing, off shore drilling, under sea floor gas-pipe line construction and maintenance, naval exercise, diving, yachting, and so on, about little to nothing has been investigated and is understood.
The facts are conclusive. “Global Climate Change” cannot cause a special rise in temperatures in Northern Europe, neither in the North Sea nor the Baltic or beyond. Any use of the oceans by mankind has an influence on thermo-haline structures within the water column from a few cm to 10m and more. Noticeable warmer winters in Europe are the logical consequence.
North Americans should not think themselves unaffected by all this.
Consider this graphic of the Siberian Express:
The more the Atlantic weather governs the situation beyond the Ural the further Polar and Siberian cold will be pushed eastwards, called ‘Siberian Express’(Fig.10). This was felt in Alaska, Canada and Eastern U.S. Many days were extremely cold with deviations from the mean of 20°C and beyond.
