This Lake Was the Last of Its Kind in Canada. And It Just Vanished
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.

Opening excerpt (first ~120 words) tap to expand
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. Washed away Epishelf lakes are rare bodies of fresh water that float directly above the denser saltwater of the ocean.
