Antarctica’s ice is shrinking at an unprecedented rate that could imperil coastal regions worldwide


Over the entire 25-year period, West Antarctica’s ice loss rate has risen from 53 billion metric tons per year to 159 metric tons annually. On the Antarctic Peninsula, ice loss has shot up from around 7 billion metric tons per year to 33 billion metric tons annually. The numbers are less certain for East Antarctica, which seems to have gained, not lost, ice over that period, though at a meager rate of 5 billion metric tons per year.
