The last epishelf lake in Canada has vanished after the Milne Ice Shelf broke up in 2020, draining into the Arctic Ocean and not expected to recover, according to a recent study.

Epishelf lakes are unique freshwater bodies that float on denser seawater, protected by ice shelves. The loss of this rare ecosystem highlights the rapid changes occurring due to warming temperatures.

The disappearance underscores broader concerns about glacial retreat and its implications for Arctic biodiversity and coastal stability.
