This Lake Was the Last of Its Kind in Canada. And It Just Vanished
Scientists have documented the disappearance of Canada's last epishelf lake following the collapse of the Milne Ice Sheet in 2020. The study highlights how climate-driven ice shelf loss destroys unique freshwater ecosystems that float above marine environments.
Why it matters
The loss of this ecosystem serves as a critical indicator of the rapid environmental degradation occurring in the Arctic due to climate change.
In July 2020, a giant Arctic shelf collapsed in Canada, losing more than 40% of its surface area in just two days. The Milne Ice Sheet acted as a dam, trapping a layer of freshwater above the Arctic Ocean. Within months of its breakup, that freshwater lake drained into the ocean and completely disappeared.
In a new study, a team of scientists reconstructed the death of Canada’s last epishelf lake as warming temperatures take their toll on the unique Arctic ecosystem. The findings, published in the journal Scientific Reports, highlight the loss of the Milne Fiord lake as a sign of the vulnerability of Arctic sea ice against climate warming.
