Between 2022 and 2023, Antarctica lost an average of 150 billion tons of ice, which obviously contributes to global sea level rise. In order to illustrate in a very simple and very visual way the transformation that the south pole, NASA created an animation showing the evolution of the continent since 2002.

Areas in orange and red are where ice is melting, while areas in light blue are where ice is gaining. In white, those where no significant change was observed. Some areas, like East Antarctica, benefit from a small amount of additional ice due to snowfall, but the volume gained is still very small (hence the light color, not dark). In dark red, you can clearly see the huge loss of ice that is getting worse every year in West Antarctica. The curve on the left, which drops drastically from 2007 and even more in 2016 (the hottest year recorded), provides an overall view of the acceleration of ice melting.
