Whales threatened by Climate Change, apparently, even though no one has asked them this

Just as well that the Japs are harvesting some before they’re extinct eh?

The sight of thousands of whales surfacing, jumping and playing off the coast of South America as they migrate toward their breeding grounds is one of nature’s most majestic displays.

But global warming is killing off their food and changing their age-old migratory routes.

To the tourists watching a humpback whale frolic with her newborn calf in the tropical waters off Ecuador’s coast near Puerto Lopez, the sight of enormous fins surfacing, tails flipping and blowholes spouting is breathtaking.

The same scenes can be found up and down the South American coast, from Puerto Piramides in Argentina to Cabo Blanco in Peru and Bahia Malaga in Colombia.

But to marine biologists, these huge mammals are not as carefree and healthy as they appear.

They are skinny, covered in parasites and exhausted from the increasingly long journeys they are making to reproduce. ?

“You can see their bones. They’re sick. They have parasites. We never used to see that,” said Ecuadorian marine biologist Cristina Castro as she scanned the horizon for more humpback whales, the species she has studied for the past 18 years.

These whales swim thousands of kilometres each year from Antarctica to the waters around the equator to have their young, which measure 3-4.5m at birth and can weigh up to one tonne.

But as ocean temperatures rise, whales are migrating earlier and travelling further.

Warmer waters are killing off the supply of krill, the small crustaceans that are whales’ main food source in their Arctic feeding grounds. The whales eat several tonnes a day to fatten up for their journeys.

Rising temperatures also trick the whales’ biological clocks into thinking it is time to migrate.

“They are changing their migration cycles. They used to arrive here in July. Now we see them in May,” said Castro.

Whales are also continuing north beyond the equator, as far as Costa Rica ? a behaviour never seen before, she told AFP.

I call bullshit on this.

There is no evidence krill are disappearing. And the waters aren’t warming, neither is the ice melting…and even if that was all true I really don’t believe that a 1 degree increase in temperature, which is claimed) could even be felt by a whale. I mean ambient air temperatures drop and rise by more than that each day.
