Record low 2022 Antarctic sea ice led to catastrophic breeding failure of emperor penguins

P. T. Fretwell, A. Boutet, et al.

A groundbreaking study by Peter T. Fretwell, Aude Boutet, and Norman Ratcliffe reveals a shocking breeding failure among emperor penguins in the Bellingshausen Sea, directly linked to record low sea ice extent in 2022. Satellite imagery shows that four out of five colonies faced total breeding failure as sea ice broke up before the chicks could fledge, marking a significant moment in understanding the impact of climate change on these vulnerable birds.
