I'm confused. The scientist says that they are dying due to global warming but that the cause of death is them swimming into patches of too cold of water.
I just read where the first live one of these species was photographed near Japan. In the article, they said that the species lives below 3000 feet in the ocean. In those depths, the water temperature are constant all year round.
Stinker. I should have excerpted the portions that I was interested in so you wouldn't think I was referring to the deaths of squid, which I'm not. I was referring to their appearance in northern waters.
Warming of ocean waters * "...man-sized Humboldt squid normally found in the the tropics..."
* "Oceanographer Howard Freeland at the Institute of Ocean Sciences says coastal waters continue to be up to three degress Celcius warmer than normal, and show no sign of reverting back to normal."
* "A year ago a jumbo squid surprised Port Renfew recreational fisherman Goody Gudmundseth and caused worried scientists who say its appearance could be another sign of global climate change."
Why?
* "...may be that the Humboldt are migrating north at this time of year in search of new sources of food..."
Gidget's conclusions
It could be argued that warming trends in northern waters, that are not normal hunting grounds, cause the squid to venture further north. Why are there warming trends? While not directly attributed to global warming, it is fact that warming temperature in the polar caps & the resulting melting effect of the ice caps "reduces the contrast with water from warmer southern latitudes, which is part of the driving force for ocean circulation." (NASA) [I could go into the weakening of the currents and thus the reduction in water exchange leaving warmer pools of water standing along coastlines, but I’ll spare you a scientific speech. Plus, I don’t have the time to collect all the data to “write a paper”. lol] When you do the domino effect – warming arctic waters = warming mid-ocean waters (due to a reduction in arctic water exchanges) = change in hunting grounds for sea mammals …I think this is a pretty good starting point to argue about the effects of global warming.
From all that I have read, giant squids die when in warmer waters because it affects their boyancy mechanism. This is why the most dead squid are found beached near places where opposing warm and cold ocean currents are close to each other. But if global warming were an issue, they should be migrating further north all the time and not having more of them wash up on the California shores.
The guy who wrote your linked article is saying squids prefer warm water which is contrary to everyone else. Hence my confusion.
I don't doubt that global warming is happening. But of what I am not convinced is that it isn't just part of a cycle or that it is the main culprit in all things blamed upon it these last couple decades.

I'm puzzled.
I forgot, my source was the National Geographic New website.
