The future of Penguins Emperor It becomes more and more uncertain. According to a study published on Nature Communications: Earth & Environment And led by Peter Frentwell of the British Antarctic Survey, this symbolic species of Antarctica could disappear completely by 2100if the current trend is not reversed.
The research, based on Satellite images collected between 2009 and 2024monitored the evolution of the colonies of penguins in a large area of theWestern Antarctica. It is an area that covers 2.8 million square kilometersequal to nine times the surface of Italy, and includes crucial regions for the survival of the species such as the Antarctic peninsulaThe Weddell sea and the Bellingshausen sea.
The census of the emperor penguins is not easy: the extreme conditions and the enormous territorial extension make direct reliefs difficult. That’s why the satellite photographs They proved to be a fundamental tool to identify the colonies and estimate their numerical consistency.
The main cause is global warming
The most recent data, updated to 2024they speak clearly: the population of the emperor penguins is decreased by 22% in 15 yearswith an average drop in the1.6% per year. A more serious trend than the initial forecasts and which lights an alarm bell in the scientific community.
The main cause of the decline is linked to global warmingwhich is gradually reducing the sea ice platforms. These floating surfaces are essential for the nesting and growth of childrenbut today they always melt before the arrival of the Antarctic summer, compromising the entire reproductive cycle of the species.
A worrying reduction of about 10%had already been observed in 2018, but the most recent update shows how The worsen is continuous and constant. Although the study examined only a portion of Antarctica, that area is considered representative of the entire ecosystem and particularly relevant due to the presence of numerous colonies.
Scientists fear that if effective measures will not be implemented to limit climate change, emperor penguins can really disappear by the end of the century. A loss not only symbolic, but also indicative of the fragility of polar ecosystems in the face of the impact of human activities.
