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, et cetera.
It can be concluded with high confidence that none of the mentioned climatically ‘external’ forces caused the shift toward cooling.
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, 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:
- Oceans and seas run their “business” according to their physical conditions, without being seriously affected or influenced by external or global physical events, or by any impact of a several years long naval war.
- Naval war changed the structure and composition of seas and oceans in a way that made global climate cool down for several decades.
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,
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.
