This was the last lake of its kind in Canada. Now it's gone.

Scientists have confirmed the disappearance of Canada's last epishelf lake, a unique freshwater body floating on saltwater, along with its distinctive ecosystem. This loss highlights the dramatic changes occurring in the Arctic due to climate change, raising concerns about the broader environmental impacts. The lake's disappearance underscores the urgent need to address global warming and its effects on polar ecosystems, which are crucial indicators of climate health.
