The pod apparently escaped Wednesday or Thursday when a path broke open.By Miranda Leitsinger, NBC NewsThe plight of a pod of killer whales that got trapped by ice in a mostly frozen Canadian bay this week was a “good example of what climate change can do” in the Arctic, a researcher said Friday.

The 11 killer whales apparently escaped the ice in Hudson Bay late Wednesday or early Thursday morning, when shifting currents helped break open a path to the sea, according to Petah Inukpuk, mayor of Inukjuak, a remote Inuit village in Quebec where locals had crafted a plan to help the animals, also known as orcas. Other reports said there were 12 orcas in the pod.

The killer whales were hundreds of miles from where they should be at this time of year, such as in the Hudson Strait or the North Atlantic, said Lyne Morissette, a mariner researcher with the Quebec-based St. Lawrence Global Observatory.
