Re “Climate conditions on Earth depend on cycles” Not necessarily so. Here is a fine example that we know too little how climate works, and man can alter climate cycles quickly!
This would merely require to take the published observations of A.J. Drummond in 1943 seriously and to investigate them thoroughly. The decisive findings are as follows:
• “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 forever”.
• 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. (underline added)
• “Never since the winters of 1878/79, 1879/80 and 1880/81 have there been in succession three so severe winters as those of 1939/40, 1940/41 and 1941/42.”
• “Since comparable records began in 1871, the only other three successive winters as snowy as the recent ones (1939/40, 1940/41 1941/42) were those during the last war, namely 1915/16, 1916/17 and 1917/18…”
