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 world's ocean has been warming rapidly, absorbing much of the planet's excess heat. As a result, large glaciers on or around Antarctica that come in contact with the warming water have been melting rapidly. But some other glaciers farther inland on the continent are actually growing. That has not been satisfactorily explained, says Schmidt.
