were able to map where and how much ice has been lost across all of Antarctica since 1979. Ice mass loss per year from 1979 to 1990 was about 40 gigatons per year. In the following decade, that number increased to 50 gigatons per year. Then, the rates took off: 166 gigatons from 1999 to 2000, then 252 gigatons per year from 2002 to 2017. The loss happened in both East and West Antarctica, but mostly in specific places in each region.
