Viewed from above, the extent of land and sea ice in the far south has not changed as dramatically as in the far north. “Now that we have mapped the whole edge of the ice sheet, it rules out any chance that parts of Antarctica are advancing. The net effect is that the ice sheet overall is retreating. We’ve looked everywhere now.”The results could prompt an upward revision of sea-level rise projections. The study’s lead author, Hannes Konrad, said there was now clear evidence that the underwater glacial retreat is happening across the ice sheet.
