Humans changed climate – 100 years ago –
Which is still ignored by Science!
Post January 02, 2021
A sudden warming was felt all over the Northern Hemisphere. Today it is called Early Arctic Warming (EAW) and started after a very cold European winter 1916/17 in 1918. Naval warfare in Western Europe was at its highest in 1916 and 1917. Several thousand ships, war ships and submarines were sunk. All water masses churned by the navies flow north towards the Arctic. In 1918 air temperature increased in the Northern North-Atlantic dramatically. It should be regarded as a clear sign, how humans can influence and change climate!

Washington Post reported on 2 November 1922 based on information by the American consul in Norway to the U.S. State Department in October 1922 and published in the Monthly Weather Review with the sensational hint that in 1918 a strong warming began (see Fig above 
left). In August, 1922, the Norwegian Department of Commerce sent an expedition to Spitzbergen and Bear Island under the leadership of Dr. Adolf Hoel, lecturer on geology at the University of Christiania. Its purpose was to survey and chart the lands adjacent to the Norwegian sea mines, laid during First World War (WWI) on those islands, take soundings of the adjacent waters, and make other oceanographic investigations.
Ice conditions were exceptional. In fact, so little ice has never before been noted. The expedition all but established a record, sailing as far north as 81° 29′ in ice-free water. This is the farthest north ever reached with modern oceanographic apparatus.
The character of the waters of the great polar basin has heretofore been practically unknown. Dr. Hoel reports that he made a section of the Gulf Stream at 81° north latitude and took soundings to a depth of 3,100 meters. These show the Gulf Stream very warm, and it could be traced as a surface current till beyond the 81st parallel. The warmth of the waters makes it probable that the favorable ice conditions will continue for some time.

In connection with Dr. Hoel’s report, it is of interest to note the unusually warm summer in Arctic Norway and the observations of Capt. Martin Ingebrigsten, who has sailed the eastern Arctic for 54 years past. He says that he first noted warmer conditions in 1918, that since that 
time it has steadily gotten warmer, and that to-day the Arctic of that region is not recognizable as the same region of 1868 to 1917. Back in 2003 Willis Eschenbach did a closer examination of Vardø (see the Vardø –above) and also found the same discontinuity around 1920, amounting to 0.73°C. When that artificial discontinuity is discounted, the temperature rise is only +0.12°C per century, a tiny result for a region that according to the models should have undergone rampant warming in the last century. The text was published in October 2003 (see left) at http://www.john-daly.com/press/press-03b.htm , in Willis Eschenbach’s eyes the late John Daly was an early giant in the climate blogger sphere.
A detailed analysis is available in the Book, 2009, “ARCTIC HEATS UP – Spitsbergen 1919-1939”, p. 60ff; (online: http://www.arctic-heats-up.com/chapter_5.html) of which an excerpt is given as it follows:
Spitsbergen as a Heating Spot
If one asks whether the heating-up spot is to be found at Spitsbergen, we would answer: yes. The information supplied sustains this affirmative answer. Nothing demonstrates this better than the data record taken at Spitsbergen since 1912. If one reviews the January/February temperature difference between the winters of 1913/14 and of 1919/20 (ca. + 15oC), or from the winters of 1916-1917 to the winters of 1919-1920 (ca. + 22oC), the results are not only extraordinary, but they reveal that the “shift” took place in 1918, respectively in the winter of 1918/19 (Hesselberg, 1956). This is emphasized by the comparison between the data recorded from 1912, until WWI ended in November 1918 (ca. – 4.3oC), and thereafter (ca. +3.8oC), including the winter of 1925/26

In the summer of 1918 the seawater temperatures had already reached unusual values: +7oC to +8oC at the West coast of Spitsbergen 
(Weikmann, 1942). During the winter of 1918/19 the temperatures varied considerably. There were long periods in November and December 1918 with temperatures close to zero degrees, 4 days with temperatures above zero in November and 7 days in December[38]. In January 1919, the temperatures did not reach -5oC for 14 days, and five days were frost-free. The annual mean (1912-1926) with a minus 7.7oC suddenly jumped to an annual average of minus 5.4oC in 1919, representing a plus of 2.3 degree. The corresponding figures provide for January 1919 a difference + 8.6oC, which indicates that the sea was able to transfer a lot of heat into the air. However, during February-April 1919, the temperatures were well below the average (ca. -6oC), with a large ice-cover far out into the sea. But that did not affect the significant warming that had started a few months earlier and lasted until the outbreak of WWII in September 1939. 
The dramatic temperature rise in the 1920th and 1930th is shown in several of the Fig. attached.
CONCLUSION:
100 years ago the sea water temperatures at Spitsbergen suddenly reached unusual high values. After winter 1918/19 the warmth affected the entire Northern Hemisphere. In the USA it warming lasted until about 1933, elsewhere to winter 1939/40. The connection to the naval war activities in the North Sea and Eastern North Atlantic is obvious. Some six-thousand ships were sunk. Many millions explosions at the sea surface and many dozen meter below the surface shock the sea and churned it around, mixing the temperature and salinity structure thoroughly. More than 100 years have passed, and science knows nothing about the issue, neither shows any interest to know how much man has contributed to the climatic change for two decades. The EAW persisted over the next two decades and lasted exactly to the moment World War II commenced.
