Arctic sea ice shrinking research says human activity carbon emissions difficult relationship 3edyy

Arctic sea ice shrinking study of human activities to the relationship between carbon emissions, according to Central News Agency reports, according to a study of carbon dioxide and a direct link between the Arctic sea ice shrinking, greenhouse gas emissions drove 4000 kilometers, will lead to an area of 3 square meters of Arctic sea ice melting. Reported that the long-term trend since 1950s, Germany and the United States scientists study the Arctic sea ice, and in the current emissions inferred by the middle of 2040s, around the Arctic will be ice free in summer. They found in the historical records, each ton of carbon dioxide into the atmosphere, which means an average of 3 square meters of sea ice loss in September. Sea ice area usually reaches its lowest value in September before winter expansion. The German Marx Planck Institute of Meteorology and the National Snow and Ice Data Center scientists wrote in "science" magazine, personal carbon emissions and may be related to loss of Arctic sea ice. They estimate that about 4000 tons of carbon dioxide will be emitted by each passenger sitting on a return trip from New York to Europe, or a petrol car. But some scientists say the study is too simplistic. Wade, a professor of marine physics at the University of Cambridge, said: "it sounds like a rather crude equation." He said that the Arctic sea ice is not as early as 2017 or may be due to man-made climate change caused by other factors, such as wind direction change and the rise in the temperature of the ocean, such as the sea, the sea temperature rise in the United States and the United States, the United States and other countries, such as the wind in the sea in the early or so.相关的主题文章:
