Too bad that salmon and most of the plankton that supports the vast food chain of the north pacific does not!
I. The insignificance of modern “global warming”
Today’s ocean temperatures average about 16°C. CO2 levels hover around 400 parts per million (0.04%).
The oceans have warmed at a rate of just 0.015°C per decade since 1971 in the 0-700 m layer according to the IPCC (2013). This warming rate isn’t detectable when considering overall long-term changes in this layer (Rosenthal et al., 2017) during the Holocene.
O.K. well here is what my Msc son, fish scientist, thought of this:
to use global average sea temperature changes when examining a localized species is misleading. The ocean has been warming unevenly, and of course, such a massive body of water will change temperature very slowly, but in some spots, especially further from the equator, change has been happening more rapidly. For species that only live in those zones, they are going to have a hard time coping with a rapid upward shift in temperatures.
Well, it appears that species can adapt quite well.
Salmon, Coho is a predator fish that lives into the Pacific Ocean and the rivers flowing into it from northern Japan to the Anadyr River, Russia, and from P. Hope, Alaska south to Monterey Bay, California. Infrequently, it has been reported at sea as far south as Baja California (USA). Salmon Coho is has been transplanted into the Great Lakes (USA) and into freshwater lakes in Alaska and along the U.S. Pacific coast as well as into Maine, Maryland, and Louisiana in the east, Alberta in Canada, as well in South America like Argentina, and Chile .
Could you remind folks what happened to the coho smolts that the Puntledge River hatchery tried raising in too warm a water? What happened to that program now that the water that they use has increased in temperature?
And this has what to do with the difference between warm blooded, mammals, and cold blooded, fish, animals.And this has what to do with the ocean temperature?
and currently the sea surface temps there are in the 13-17C range. see: https://www.seatemperature.org/south-america/
talk about an indefensible assumption.
Also thought those fish farmers told us that there are no impacts from FF activity - wonder where those Chinook came from then?
