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.
NASA says although some of Antarctica's ice is melting, other parts are growing so fast the ice sheet is actually slowing sea level rise. Considering it's a barren, unimaginably cold wasteland at the bottom of the world â where penguins far outnumber people â Antarctica is sure making a lot of news these days. A recent study in the Journal of Glaciology reported that despite the effects of man-made global warming, the frozen continent is actually gaining ice rather than losing it.
