Antarctic ice gains reported

Recent satellite data show that Antarctica gained ice mass between 2021 and 2023, adding about 119 billion tons per year, according to a study in Science China Earth Sciences. This is the first time in over two decades that the continent has seen a net increase in ice.

Contrast with earlier ice loss

This gain contrasts with the overall trend of ice loss observed between 2002 and 2020, during which Antarctica lost more than 150 billion tons of ice annually. The study attributes the recent increase to higher snowfall driven by increased atmospheric humidity linked to global warming.

Snowfall temporarily offsets loss

The phenomenon highlights the complexity of climate change impacts, as increased snowfall can temporarily offset ice loss in some regions. However, experts stress that this gain does not reverse the long-term trend of ice loss, particularly in Western Antarctica, where glaciers are melting and contributing to rising sea levels.

Expert warns of ongoing risks

Tom Slater, a researcher at Northumbria University, notes that while the increase in snowfall provides a temporary reprieve, the continued melting of glaciers elsewhere in the continent remains a critical concern for global sea level rise. Antarctica holds about 90% of the planet's fresh water.

Need for continued monitoring

The findings underscore the need for continued monitoring of Antarctic ice dynamics, as they play a crucial role in understanding and predicting the broader impacts of climate change.
