Satellites that monitor Antarctica indicate that it is now losing 200 billion tonnes of ice to the oceans every year. This in result is pushing global sea levels by 0.6mm annually. This is three times the rate in 2012.Researchers say that these losses in ice are occurring predominantly in the west of the continent where conditions favor this effect more. Warm waters get under and melt the fronts of glaciers that terminate in the ocean.Professor Andrew Shepherd, who leads the Ice sheet Mass Balance Inter-comparison Exercise (Imbie) says that it is about a half a degree Celsius warmer than the continent can withstand.According to study, published in the Nature , where more than 80 researchers from 42 international organizations presented their findings, ice loses in the region contributed to a global sea level rise of 7.6mm between 1992 and 2012. Forty percent of this rise occurred during the last five years alone.
