The deep fall from Warming Europe to the Ice Age

 

Thesis

The pre WW II years were the warmest since the 16th century. A big warming period, during the 1920s and 1930s ended in winter 1939/40. After only four war months, the first war winter was the coldest winter in 100 years in Northern Europe. This ending came with an extraordinary suddenness. The change was so dramatic that a natural cause can be excluded with high certainty. Nothing serious had happened around the globe during 1939 except that WW II had started on September 1st 1939. The climatic shift to extreme winter conditions was caused by the war at sea in the North and Baltic Sea.

 

Facts

A global warming had started around the 1880s. When the 1910-20 decade ended, the warming accelerated in the northern hemisphere, temporarily at some locations, but lasting for two decades in Europe. Scientists of that time spoke of the ‘Warming of Europe’. The 1930s decade was recorded as the warmest observed. The weather conditions were normal in every respect. Neither the sun, nor orbiting meteorites nor volcanic activities disturbed the course of climate.

In autumn 1939 1,000 naval vessels went out to the sea on combat missions; several thousand airplanes flew out to bomb enemy vessels, many ten thousands of sea mines were laid in the North Sea and Baltic Sea. The seas were stirred and shaken. They blocked Europe off from maritime influence and paved the way for continental conditions. Two significant events on the verges of European continent remained sidelined, the December 1939 invasion of Finland by Russia, and the earthquake on December 27th in Turkey.

In early January 1940 Northern Europe found itself back to weather conditions not experienced in Europe since the ‘Little Ice Age’ more than 100 years earlier. After the extreme cold spell in January came an unusual second extremely cold spell in February.

 

Evidence

The link between the temperature decrease in winter 1939/40 and the war activities is obvious because:

  • The temperature difference to previous winters is of such magnitude that a connection to the war activities is given by time and location.
  • There is no other explanation for the sudden shift in climatic conditions than the war at sea.
  • The second severe cold spell in February 1940 proves that the Europe’s northern seas were deprived of summer-stored heat too early by the war machinery ploughing the seas during the autumn months in 1939.
 

Conclusion and further reading

The sudden stopping of the general warming trend since the 1880s and the accelerated warming of Europe from about 1920 to 1939 can only be explained by the war at sea that started only few months earlier in September 1939. Winter 1939_40 (2_11), Lost West Drift (2_12), and Sea war events (2_13), and Russia-Finnish war (2_41), and Turkey quake December 27th (2_51).
