et.al, basically confirmed this (Fn.3), stating in their conclusion: “The
Arctic 1920-1940 warming is one of the most puzzling climate anomalies
of the 20th Century”.
But is it really that puzzling? The first step toward clarification
would be to come to the same conclusion as this web-site material does,
that the ‘Big Warming’ started at the end of WWI, in winter
1918/19, and the second step requires attention to the devastation
naval war in sea areas, closely connected to Spitsbergen by the
Norwegian- and Spitsbergen Current. When Johannessen et.al.
(Fn.4) conclude: “that the Arctic warming in the 1920s/1930s and the subsequent cooling
until about 1970 are due to natural fluctuations internal to the
climate system”, it is mere guessing.
The pronounced warming since 1919 was most likely closely related to
WWI, the ‘subsequent cooling’ by WWII, which got its ‘kick-off’
with arctic war winter 1939/40. Naval war is a sufficient means to
influence the ‘internal of the climate system’, namely the oceans.
As long as the IPCC is not even able to
get the ‘timing’ of recent arctic warming correct, although the
cited papers (Fn.3 & 4) came at least close to it, IPCC competence
in making reliable outlooks for forthcoming climate should be not
weighted too high. The material available on our sites offer plenty
facts and convincing correlations on recent climatic causations.
Actually in some cases the best!
