An undated photo from the Center for Northern Studies shows the Ward Hunt Ice Shelf disintegrating. The incredibly rapid rate at which Canada's Arctic ice shelves are disappearing is an early indicator of the 'very substantial changes' that global warming will impose on all mankind, a top scientist said on Wednesday.

Formed by accumulating snow and freezing meltwater, ice shelves are large platforms of thick, ancient sea ice that float on the ocean's surface but are connected to land.
"These changes are irreversible under the present climate and indicate that the environmental conditions that have kept these ice shelves in balance for thousands of years are no longer present," said Mueller.
today, warmer temperatures and a changing climate means there's no hope for
regrowth.
The loss of these ice shelves means that rare ecosystems that depend on them are
on the brink of extinction
