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.
It's tempting to say that the climate at the South Pole is consistently cold, but it is not. In December it is very cold, with an average temperature of around -28â (-18â). However In July it is astonishingly cold, with temperatures sagging to -80â (-112â).ntarctica is (for obvious reasons) the least-visited continent, and the South Pole is (because it is not accessible by sea) the least-visited site in Antarctica that is nominally open to tourism. Most expeditions take place in November thru January, during the Antarctic summer/day.
