Another sign


Nature is one of the best indicators of climate change.  And now nature has provided another sign that the climate, this time affecting the ocean, is changing.

"In a paper in the journal Global Change Biology, more than 30 researchers from institutions in the United States and Canada considered over 35,000 recordings taken from passive acoustic recorders. The underwater microphones ranged from western Greenland to the Caribbean Sea, and the data represented whale calls recorded between 2004 and 2014.

The researchers found that fin, sei, humpback and blue whales all spent more time in northern latitudes over the decade. After 2010, the time they spent in the Gulf of Maine, the land off the coasts of New England and Nova Scotia, declined."
So, stated in Yankee words, the whales are summering longer.
