Antarctica global warming has become a burning issue of the present time. Global warming in Antarctica will pose a serious threat to the rise in water level. Hence, Antarctica global warming has become a great concern for the scientists and researchers. As most of this continent is covered by ice, the impact of global warming is more acutely felt here. With the increase in the number of automobiles, air pollution has been on the increase in the last 20 years. This is one of the major causes of global warming.
Antarctica is centered at the Earth's south pole, and so receives very little sunlight. Much of the sunlight it does receive is reflected back to outer space since most of the continent is covered with snow and ice, which further cools the continent. As a result, Antarctica is the coldest place on earth. It also manufactures cold air masses, which are continuously flowing off the Antarctic ice cap, sometimes producing winds in excess of 100 mph.
