The Marine Animal Response Society says recent whale sightings raises questions about the impact of climate change. A humpback whale that was spotted in the Shubenacadie River earlier this week has died and a blue whale resurfaced in St. Marys Bay after 22 years.After a humpback whale was spotted in the tidal waters of Nova Scotia's Stewiacke River in the last week, area residents spotted one the size of a small bus beached on a sandbar when the tide went out.
"The ocean seems to be changing," she said. "It's warming, the food is changing, the food quality is changing, the animals themselves, their health, and so it does raise some alarms." Wimmer said it's not clear why the whale was in the Shubenacadie River to begin with, but it may have been following fish.Gaylene Chase was among several people who gathered along a trail not far from the river. She heard about the whale and said she was curious.
