The Arctic malaise is obvious. The Polar area permanent ice cover retreat is the biggest ever observed. The suddenness is unexpected and Arctic experts do know little regarding the chain of possible causation, some of them explaining to Andrew C. Revkin that “ things are not that simple”. But could the situation not have been more clear if more attention had been given to the Big Warming at Spitsbergen which started at the end of WWI in winter 1918/19.
It is more than a half century ago that Birkeland regarded temperature rise in the Arctic since 1918/19 as the biggest ever observed, while Ahlmann named it a “climatic revolution”. As the deviation from means had been even more pronounced, as during the recent two decades, it seems reasonable to understand the preliminary Arctic warming in the first place for not being too unnerved with the situation know. This site offers the interested reader a lot of clues, as it investigates the event step by step: Where, When, and Why. Based on the fact that the rise in temperatures occurred during winter when the direct influence of the sun is zero, the next observation is at hand, that only the sea could have started and sustained the warming. Broadly speaking, this all could only have started with the permanent supply of warm water from the South and at the West Coast of Spitsbergen, due to the extensive sea ice during the winter season, which usually culminates in April. The presented images illustrate the situation well (for details see Chapter C & D).
- The plain graph (from 1914) indicates the usual situation in the Northern North
Atlantic between Land, Sea, and Sea Ice in the month April.
- One further graph (April 1919) shows the flow of the water current carrying warm water from the Gulf Current and brackish water from the North Sea northwards.
- The third graph (April 1919) with the read triangle at Spitsbergen indicates that the warming impulse could only have been generated in this small section.
This scenario reveals that the sea has generated the Artic warming 90 years ago, and that it would be of big help for understanding the current situation better if this would be acknowledged and vigorously investigated. This website, which is fully dedicated to this topic, hopes to be a contribution, and for the interested reader the early Arctic warming issue is plainly explained.
