The Antarctic contains 99% of the world’s glacial ice and some of the most incredible ice formations. Unfortunately, some of the glaciers have begun to melt. The Totten Glacier of East Antarctica is losing ice because warm water is pooling underneath it. According to the Australian Antarctic Division, the amount of ice lost is “equivalent to 100 times the volume of Sydney Harbour every year.”
