Scientists confirm cetacean’s presence but cite impact of climate change which has made North-west Passage ice-free in summer

Scientists have confirmed the presence of a whale off New England that went extinct in the Atlantic Ocean two centuries ago – an exciting discovery, but one they said that illustrates the impact of climate change on sea life.

Researchers with the New England Aquarium in Boston found the gray whale while flying 30 miles south of Nantucket, Massachusetts, on 1 March. The whale, which can weigh 60,000 pounds (27,215kg), typically lives in the northern Pacific Ocean.
