A vast area of sea ice in West Antarctica, equivalent in size to France, has disappeared even during the winter season. Satellite observations reveal that the Bellingshausen Sea, located west of the Antarctic Peninsula, is now almost entirely ice-free. This significant loss poses a severe threat to marine biodiversity, particularly impacting penguin populations. Furthermore, scientists warn that this trend could contribute to a rise in global sea levels. The phenomenon is being closely monitored as researchers compare current data with averages from 1991 to 2020. The disappearance of this ice shield disrupts the delicate balance of the polar ecosystem. Consequently, the international scientific community is raising alarms over the accelerating pace of polar melting.
