The domain was not a fun place between 1914 and 1920 . As if the horrors of the First World War ( 1914 - 1918 ) were not hellish enough , much of the world then had to deal withthe “ Spanish flu ” outbreak , a pandemic that ’s thought to have pass over out over 50 million multitude worldwide . It twist out this unfortunate serial of result might have been worsened by a short but sharp blip in the Earth ’s climate that resulted in capriciously cold and wet weather in northern Europe .
In a new field publish inGeohealth , an international team of scientist analyse a 72 - meter - long ( 236 - human foot - long ) ice core film from the Colle Gnifetti glacier in the Swiss - Italian Alps and key out a “ once?in?a?century climate anomaly ” that resulted in increased wet and cold conditions from the north Atlantic during the First World War .
Within the 2,000 years of climate account embedded in the methamphetamine core , the researchers discovered noteworthy changes in the levels of sodium and Cl , component establish in sea Strategic Arms Limitation Talks , in the layer that related to the years 1915 to 1918 . agree to the researchers , this intelligibly indicates the Alps and much of northwestern Europe were probably hit by a strong influx of cold North Atlantic sea air , bringing in colder aviation and a deluge of rainfall .

Other source from the time , such as written document or photograph , often present this geological period as a deary and hoary time , with barbed - wire line trench filled with rainwater and clay . It appears this image might not be far from the truth .
In bit , the investigator reason that this harsh turn of conditions might have further deepened the rigor and casualty brought on by World War One . Along with the threat of bullet and mortar , soldier fight this arduous warfare also had to care with disease and trench foot , a foul shape when the animal foot are blind drunk for foresighted menses of time . These dangers would have been made importantly worse from the rough weather experienced at the time , say the researchers .
“ We find out that mortality in Europe peak three times during the warfare , and these peaks go on during or soon after periods of stale temperature and heavy rain have by extremely strange influx of sea air in the winters of 1914 - 15 , 1915 - 16 and 1917 - 18 , together offer a once in a 100 - year anomaly , ” Dr Alex More , subject area author from Harvard University and the Climate Change Institute , University of Maine , and associate prof in environmental health at Long Island University , New York , explained in astatement .
Furthermore , they also colligate this climate anomaly to the strong waves of the Spanish flu . Not only would more humid conditions favour the spread of respiratory disease but the unusual climatic conditions may have also had a unsounded gist on mallard ducks , one of the master brute artificial lake for the H1N1 strain of influenza . The investigator indicate that the migrations of mallard duck and other migratory bird would have been profoundly disturbed during the war twelvemonth , meaning they were more probable to stay in Europe where they could easy convey influenza to human by water contaminated with their poop . understandably , this is just one small part of the puzzle , but the researchers argue it could have played some function in the disease outbreak .
“ These atmospherical reorganizations bump and they touch people , ” Dr More say in anotherpress release . “ They feign how we move , how much water system is available , what beast are around . Animals bring their own diseases with them in their movements , and their migrations are due to the surround and how it changes , or how we change it . ”
“ I call up it ’s a very credible , provocative study that stimulate us think in fresh ways about the interplay between infectious disease and the surround , ” sum up Philip Landrigan , a director of the Global Public Health Program at Boston College who was not involve in the new study .
