Are 70 Years Ignorance not enough?
The biggest Climatic Shift Started in Autumn 1939.
By: / 29th August 2009

Friday the 1st September 1939 can be set as turning point from a warming-up period to a period of  global cooling for three decades. Only four months after Hitler had dragged the world into World War II, Northern Europe was back to the conditions of the Little Ice Age. It was the coldest winter for more than 100 years
(For details see: Essay 2008, in left column)

Back in 1943 the British scientist A.J. Drummond observed: “The present century has been marked by such a widespread tendency towards mild winters that the ‘old-fashioned winters’, of which one had heard so much, seemed to have gone for ever. The sudden arrival at the end of 1939 of what was to be the beginning of a series of cold winters was therefore all the more surprising”[1]. And what explanation does modern science offer? Non! The possible impact of the naval war on the climate is a non issue in climatology. Is that tolerable?

OCEANCLIMATE pursues the matter since long (see material in the right column). The preface of a book titled: “War Changes Climate – The Naval War Effect”[2], raised the matter in a symbolic narrative: 

 Asta Lindskog had only ten minutes for her lunch break at mobile phone giant Ericsson’s canteen in Stockholm. And now the soup was too hot. She turned the spoon through the soup bowl. Her thoughts drifted to the looming war hoping that the British Prime Minister Neville Chamberlain could persuade Adolph Hitler not to make war. If not, what would be the future for little Eric and sweet Signe, her children of four and two, and the spoon moved quickly. “Calm down”, she ordered herself, “it will not come to the worst”. When realizing the soup was suddenly too cold her mind jump: “Sweden will hardly see a mild winter if navies at war churn and turn the Baltic Sea about as I just did with the soup.” The war started within few weeks time and all countries around the Baltic Sea experienced the coldest winter for more than 100 years.

 It came as worst as Asta had expected (see: Fig. “January Temperature in Sweden & Germany” below). Very illustrative is the general situation in January 1940, as shown in the Scherhag image published in 1951[3].  His colleague M. Rodewald[4] already recognised few years earlier that a “secular heat wave” had been felt over most of the Earth especially striking between 1900 and 1939, so that it was all the more surprising that there was a series of three severe winters in succession in 1939/40, 1940/41 and 1941/42.  Rodewald’s observation is now 60 years old and no questions have been asked why the series of three severe war winters occurred. The severity is particularly well demonstrated if reviewed as ‘package’, as successive cold winters in Northern Europe are rare[5]. By taking the full record available for Stockholm since 1756 into account, the first three war winters beat all corresponding years by length (see the three images in row). Would it not be high time to study the WWII war winters in depth and learn from it now. 70 years have already been lost.
