According to a study by UC Irvine’s Eric Ringot, and published in the Proceedings of the National Academy of Sciences, Antarctica ice melt has accelerated by 280% in the last 4 decades.

Ice loss in Antarctica has increased from 40 gigatons per year from 1979-90 to 252 gigatons per year from 2009-17. The melt-rate has been accelerating in the most recent decades, up 280% in the second half of the nearly 40 years compared to the first half.
