According to a study published in The researchers found that sea level rise had clearly crossed the threshold As early as 1863. Surprisingly, this was the time when the first effects occurred. The seas also began to feel themselves , Directly related to human activities. Warming of the oceans and Glaciers are two major causes of sea level rise.
For 1,700 years, global sea level has been subject to regular but minor variations: the level has lost 0.3 millimeters and increased to 0.2 millimeters. Between 1700 and 1760, shortly before And massive use Sea level dropped by 0.1 mm.
Between 1940 and 2000 a drastic change took place as the global sea level rose sharply to 1.4 millimeters a year! This 60-year interval (1940 to 2000) demonstrated unprecedented acceleration in sea level rise, more than anything that has happened in almost 2,000 years. Archaeological studies, analysis . On the other hand, in other parts of the Atlantic Ocean, acceleration did not begin until the middle of the 20th.And Century.And geochemistry shows that the area where this acceleration first occurred was the North Atlantic Ocean. North of the Atlantic Ocean, this sudden acceleration occurred from the middle of the 19thAnd Century, more precisely between 1820 and 1860
Correlation between global warming and sea level rise
Remember the use of fossil fuels ( And this The main gases involved in this greenhouse effect form a “lid” Part of the trap On . In addition to the melting of ice on land, the warming of the oceans a A little water. According to ” Ocean level rise is associated with the expansion of 1/3 of the oceans and melting to 2/3 Mountains and ⁇. This melting is mainly observed in the polar regions of the Arctic and Antarctica. ” The total melting sea level of Antarctica will be equal to 60 meters above sea level, and Greenland’s melting should be added to the order of 7 meters. Notice Security-Natural. According to Released in August 2021, it is expected to rise by an average of 50 centimeters by the end of the century and 2 meters by 2300 or earlier., , ) Publishes in large quantities : I ‘ Carbon dioxide, steam,
