New study reveal the main cause of Arctic sea ice expansion. Particles from air pollution is the most seen reason.
Science Daily reported that it was human fault who have been altering the Arctic sea ice. It is because of the prolonged effects of air pollution which is a result of burning fossil fuels and other harmful substances on air.
To recall, scientists have been monitoring such sea ice loss since the mid-1979s. Now, they have seen such huge changes in the subsequent decrease of sea ice in the Arctic from 1975 up to year 2005.
According to Earth Justice, the year 2012 when scientists from the U.S. National Snow and Data Center have confirmed an extent record to low. That same year has recorded the lowest amounts of Arctic sea ice since on the year 1970's. Furthermore, sea ice thickness was recorded dragged to a 40-50% making it closer to melting.
Meanwhile, scientists are on their way to slow the pace of Arctic sea ice melting. An assessment made by the United Nations Environment Program along with the World Meteorological Organization believe in the possibility of reducing emissions.
They focus is on the two common air pollutants, the soot, and smog. Specifically, black carbon and tropospheric ozone which only remains in the atmosphere in days or months is the focus of the study. Reduction of these so-called "short-lived" climate warming pollutants was seen to contribute in the goal of the researchers in decreasing the melting of Arctic sea ice.
Rosenthal, the author on the UNEP/WMO assessment said, "this would mean that reducing the emissions of these "short-lived' climate pollutants would have fast climate benefits. Besides, black carbon in air pollution is the main cause of fast melting of ice and snow."
If humans would help in decreasing the black carbon causing air pollution instead of increasing it will cause great help in the Arctic sea ice. Scientists foresee human help in this goal to decrease the effects of air pollution in the Arctic region.
