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 losing ice mass while gaining ice extent. This is a confusing point to some. There are a few keys that can help us understand what this means in the context of global warming. Land ice is different than sea ice.ntarctica is melting, not growing. In fact the ice mass is dropping at an accelerating rate due to multiple factors including accelerated glacial ice calving rates. The loss of sea based ice allows the Antarctic ice to move faster towards the ocean resulting in an increased rate of loss of the Antarctic ice.
