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 a land of extremes. Itâs not inhabited year round by humans because itâs simply too freezing cold. In 1983 scientists recorded extreme cold temperatures as low as -129 Fahrenheit. Itâs also the wettest place on earth, but simultaneously the driest. The reason itâs the âwettestâ is not because of rainfall; since Antarctica is covered by 98% ice, itâs technically very wet.
