The rate that Antarctica is melting has tripled since 2007, new research shows

Antarctica is melting at an alarming rate — and that rate continues to speed up.

The rate at which Antarctica is losing ice has tripled since 2007, according to a new report published this week in the journal Nature. The continent lost about 3 billion tons of ice between 1992 and 2017, and within that 25-year period, 40% of the loss occurred in just the past five years.

Scientists say those losses contributed to a 7.6 millimeter rise in mean sea level, and they estimate that by year 2070 sea levels could rise another half a meter from where they were in 2000.
