Although the naval war in the North Pacific took place only in the western part East of Hawaii, the sea current system ‘distributed’ the war impact throughout the Pacific Ocean north of the equator. B/W p. 208
By conducting a naval war at a global scale and by turning and churning huge sea areas of Atlantic, Pacific and Indian Ocean, the inevitable happened. Oceans and seas turned a strong warming period since World War I in a modest but nevertheless

very significant colder period that lasted for almost half a century. Mankind had changed climate after World War I a second time. Actually the experiment had started precisely on the 1st of September 1939. Hitler’s war machinery put so much stress on Northern Europe’ seas and environment that within four months the area was catapulted back in the Little Ice Age, and experienced the coldest winter for over 100 years. North and Baltic Sea were deprived of their usual winter capacity during three war winters in a row, from 1939–1942. Consequences have been described in detail in previous chapters. However, during the third arctic war winter (1941/42) in Europe, naval war was turned into a global matter.
Any correct answer to the question ‘what turned climate in a several decades long cooling phase’ would have huge political consequences. Carbon dioxide, which IPCC regards as the major contributor for ‘global warming’, can definitely be excluded as initiator and sustainers of global cooling from about 1940 until 1980. Who did it then? No one ever observed that, at the end of the third decade (1930s) or at the beginning of the fourth decade, nature did nothing exceptional, for example, earthquake, tsunami, meteorite, exceptional sunspots, etc. Actually, there was nothing of such kind; nature resumed its normal course. Industrial plants and combustion machines released abundantly smoke, soot, sulphate, carbon dioxide and other greenhouse gases into the atmosphere, but instead of getting warmer, the world cooled down. It can be concluded with high confidence that none of the mentioned climatically ‘external’ forces caused the shift toward colling.
If external matters did not determine the cooling, only internal matters could have done it. If one defines climate as the continuation of the oceans by other means (vapour instead of water), oceans and seas are definitely the only source that could and have made climate changing into a cooling down period of four decades. Once questions are settled in, only two options remain to discuss:
This investigation offers as most likely causation for the significant down turn of temperatures from 1940 until 1980 the war at sea aspect. There are good reasons to point at naval warfare. Previous sections established convincingly that naval warfare in North Sea, Baltic Sea and Eastern North Atlantic generated three extreme war winters in North Europe, establishing evidently a direct connection between war and weather modification. If regional naval warfare can change regional climate, global naval warfare can change global climate. However, demonstrating the latter case is not as easy as it was possible in the former case.
makes our discussions on global climate changes due to naval warfare
even more difficult is the fact that isolating global matters to only
the winter season is not an option. The physical features of ocean space
and regional seas in question are too different. The same happens in the
case of a geographical location, volume of water masses, and any
seasonal distinction. What actually did happen to ocean space according
time, location, and amount of explosives and naval ship movements is
known too few people. How did it change the structure of the sea surface
and affected the water body? But no aspect is so dominating as to offer
an answer to the question: What forced the oceans to cool down the
climate for almost half a century, just 65 years ago?
Approach of section
To establish a link between naval war during WWII and global climate change, the destructive forces unlashed between 1939 and 1945 will be presented in a concise manner. The aim is to demonstrate that, due to the complete lack of any natural event during the relevant time period, only war at sea remains a plausible explanation because it was a sufficient force to play in the league of major natural phenomena. A subsequent section will summarize some principle physical and geographical features of war areas in the Atlantic and Pacific for the better understanding of the highly presumable relation between ocean reactions and naval activities, with the aim of showing that there is no better answer than this one yet. After all, climate research should restrain from scaring anyone with global warming if not able to explain convincingly what made earth atmosphere cooler for four decades since WWII commenced.
In 1988, the eminent scientist Jean M. Grove wrote: “Evidently it will be necessary to understand the climate of the deep oceans before a full understanding of changes in the atmosphere can be achieved". Naval war did many things across all ocean space and ocean depths.
Even the collection of sea surface temperature measurements taken during World War II were severely affected by various reasons and should only be used with outmost reservation.
