According to new research, ice-melt in Antarctica has caused global sea levels to rise by as much as 7.6 millimeters since 1992 — and about 40 percent of that, some 3 millimeters, came in just the past five years. That’s the finding of a major climate assessment called the Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE), the results of which were published in the journal Nature last week. Prior to 2012, Antarctica lost ice at a fairly steady rate of 76 billion metric tons annually, contributing about 0.2 millimeters to sea level rise. From 2012 to 2017, however, that rate of loss increased sharply to 219 billion metric tons of ice per year, contributing about 0.6 millimeters to rising sea levels. There’s enough frozen water stored in Antarctica to raise global sea levels by 58 metres.
