Between 1979 and 1990, the researchers explained in a release, Antarctica lost, on average, about 40 billion tons of ice per year (or 40 gigatons, if you prefer). That’s not exactly slim, but it hardly compares to Antarctica’s average annual ice loss between 2009 and 2017, which weighed in at more than 250 billion tons annually.

The researchers, from the University of California, Irvine, and Utrecht University in the Netherlands, say that…
