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.
The continent of Antarctica has been losing more than 100 cubic kilometers (24 cubic miles) of ice per year since 2002. Larger Image. There has been lots of talk lately about Antarctica and whether or not the continent's giant ice sheet is melting.One new paper 1, which states thereâs less surface melting recently than in past years, has been cited as proof that thereâs no global warming.here is a continent about the size of Australia underneath all this ice; the ice sheet sitting on top averages at a little over 2 kilometer (1.2 miles) thick. If all of this ice melted, it would raise global sea level by about 60 meter (197 feet).
