A study by MacKie et al., published in Geophysical Research Letters, investigates the connection between climate change and large iceberg calving events in Antarctica. While massive icebergs like the A-68 can draw public attention, they are rare, complicating predictions. The researchers conducted a long-term analysis of the largest annual icebergs from 1976 to 2023, finding a slight decrease in their surface area. Despite climate change, the risk of extreme calving events has not increased, suggesting they are not directly tied to climate change. However, smaller calving events are becoming more frequent, leading to significant ice loss. The researchers indicated that a large iceberg, comparable in size to Switzerland, could emerge in the future.
