In a major collaborative effort, scientists from around the world have used information from satellites to reveal that ice melting in Antarctica has not only raised sea levels by 7.6 mm since 1992, but critically, almost half of this rise has occurred in the last five years. Prior to 2012, Antarctica was losing 76 billion tonnes of ice a year. This was causing sea levels to rise at a rate of 0.2 mm a year. Since then, however, Antarctica has been losing ice three times as fast. Between 2012 and 2017, Antarctica lost 219 billion tonnes of ice a year, raising sea levels by 0.6 mm a year. This information is key to understanding how climate change is affecting the most remote part of the planet and how this has consequences for the rest of the world.
