Antarctica's brief rebound was caused by climate variability, not a 'new normal'
Key Points
Between 2021 and 2023, Antarctica appeared to be growing. Heavy snowfall fueled by wetter weather caused parts of the continent to gain mass, leading some to question whether climate change is really causing the ice to melt. However, a new study shows that the precipitation increase was an anomaly related to extra-warm tropical ocean temperatures, not part of a long-term trend.
