A grey whale was seen in the Atlantic for one of the only times in the last 200 years. Scientists say it's bad news for the planet.

• Grey whales have been extinct from the Atlantic Ocean since the 18th century. 
• But scientists spotted one swimming off New England — one of a few sightings in the last 200 years.
• Scientists were thrilled to see the whale, but its presence is probably linked to climate change.

PORTLAND, Maine (AP) — 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.
