Over the past five years, Antarctica has lost about one million square kilometers of sea ice. This could seriously affect the global marine ecosystem.
Researchers studied satellite imagery and meteorological data from the seventies of the last century. Their analysis suggests that Antarctica lost a third of summer ice in the
Weddell Sea. This area can be compared with an area equal to the territory of two Spain. Scientists believe that the greatest ice losses occurred in the summer season 2016−2017, when a number of adverse weather events were recorded in the region.
