For some relief from the relentless stories of Catastrophic Anthropogenic Global Warming (CAGW), we turn today to a study of Man Made Mild Weather (MMMW). CAGW also stands for Citizens Against Government Waste, not to be confused with the first acronym. Oh wait. (sarc/off)
Specifically this post concerns work by Dr. Arnd Bernaerts on human activities contributing to mild winters in Europe.
To start with, he is analyzing “climate” properly. Climates are plural, not singular; the term is a human construct referring to distinctly local and regional patterns and expectations of future weather. Secondly, he addresses changes observed in one particular season as a way to identify inter annual variation. Thirdly, he is well aware of oceanic fluctuations, and seeks to understand human effects in addition to natural variability.
Specifically Dr. Bernaerts studies the linkage between the Baltic and North Seas and winters in Northern Europe. His article (here) is entitled “Northern Europe’s Mild Winters. Contributions from Offshore Industry, Ships, Fishery, et cetera?”
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’.
The climatic change issue would be better understood if this extraordinary regional warming is sufficiently explained. The regional features are unique for in-depth studies due to different summer-winter conditions, shallowness of the seas, geographical structure, and main pathway for maritime weather patterns moving eastwards.
The impact of sea activities on the seasonal sea water profile structure is contributing to stronger regional warming, change in growing season, and less severe sea ice conditions. The impact of the man, whether small or large, should be understood very soon and very thoroughly.
Pay particular attention to the Discussion at the end, which includes this:
Regional seas in Northern Europe are minor from size and volume in global ocean affairs. Weather is “done” elsewhere, but every location contributes to the global picture. In the case of N-Europe it may be more significant as weather can be divided in maritime and continental influence, and due to the global air circulation from West to East, it is a gate. It may support the flow of warm wet air eastward (low pressure), or stem it by dry and cold continental air (high pressure), by diverting low pressure areas– in extreme circumstances – towards the Bering Sea or Mediterranean. In so far the North Sea and Baltic play a crucial role in how to open or close this gate.
Three facts are established: higher warming, a small shift in the seasons, and a decreasing sea ice cover. In each scenario the two sea’s conditions play a decisive role. 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
Two of my heroes are Dr. Pielke Sr. for his work showing how human use of the land affects climates in the locales where it occurs, and Dr. Bernaerts for exposing how human use of the ocean impacts on nearby climates.
