HISTORY OF GLOBAL WARMINGIn 1896 a Swedish chemist by the name of Svante Arrhenius predicted that if c arbon dioxide levels doubled, the kernel global temperature would rise by 6°C. In the 1950?s, Charles Keeling monitored carbonic acid gas levels on a mountain in Hawaii. He ground that the CO2 levels had risen by 10%. By 1990 CO2 levels had risen by 20%. At this rate, CO2 levels entrust double by 2050 (Bilger 14).

Harvey 2Scientists were not implicated about global warming before Keeling because they knew that natural gases were heedless by our oceans, soils, and ve hold upation. Oceanographer Roger Reville ready that oceans could only absorb whatever of the CO2 in our atmosphere. So by the 1960?s and 1970?s global warming became a concern (Bilger 15). In the early 1970?s, the Ear th had become unmistakably cool in temperat! ure. Scientists believed that we were debut into another ice age. They believed that line of descent pollution was block off the sunlight and cooling the Earth. Nigel Calder... If you want to get a replete(p) essay, order it on our website: OrderEssay.net
