Now, apparently, fish are shrinking, thanks to falling oxygen levels in the seas:
By 2050, the size of fish could shrink by 10 - 20 per cent, Dr William Cheung, a marine ecologist at the University of British Columbia, Canada, forecast.Some might say the shrinking Haddock might have more to do with over-fishing.
Dr Cheung, who gave a keynote address at the 50th Anniversary Symposium of the Fisheries Society of the British Isles at Exeter University this week, said some fish in the North Sea, including haddock, were already getting smaller.
He predicted the trend would continue with common species such as cod shrinking by up to a fifth within our lifetime.Get ready for "child's portions" of fish and chips. No really, that's the headline, not the punchline.
Climate change will extinguish Life on Earth but if that doesn't scare you, let me tell you about your shrinking food. Kiddie meals are coming!
The marine ecologist said fish are shrinking because climate change is reducing the oxygen in the seas available for fish to breath.The marine ecologist went on to say that because oceans are warming, fish that swim around Portugal and Spain will call the UK home.
Right now the ocean around the UK is 17C — at least three degrees colder than the water off Portugal. The ARGO buoys estimate the ocean is warming at 0.005°C per year (plus or minus 0.5° C, don't laugh now.) So only 600 years to go at this rate, give or take 60,000 years.
How much is oxygen actually declining?
The rise in ocean temperature is reducing the oxygen in the waters for fish to breathe, while increasing fish's need for oxygen simultaneously. Fish are more easily 'short-of-breath' as they grow bigger.I'd like to see some measurements on those falling oxygen levels before I stock up on frozen codfish.
As the temperature of the surface of the oceans increases, the water holds less oxygen for fish to breathe. This is exacerbated because, as the seas warm up, oxygen from the depths of the ocean does not mix with the surface water as readily. In addition, water does not circulate as swiftly, which means the deep ocean is not as well ventilated.
Dr Cheong seems to be mixing up atmospheric warming with ocean warming:
In the last few decades the surface oceans have warmed up by less than a degree celcius. Dr Cheung, a former lead author in the Working Group II of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), projected that achieving the Paris Agreement of the 1.5 - 2.0 oC global warming targets will substantially reduce impacts. But if emissions are not reduced, there could be 3.5 - 4.0 oC warming, by the end of the century.Extrapolated fish are coming your way.

Note to the climate change doomsayers...

Tempura everything deep fried in Goma Abura-Rice Bran Oil.
Air Fryers Kick Ass!
Woe to the Acidification of the Oceans caused by:
Red Tide is now Red Coasts near Deltas flowing from Rivers that have Industrialized farming upriver with the Chemical Salt Fertilizers being abused to Grow Monoculturized Crops with GMO tampering then Contamination and Pesticide run-off as well
Dumping of Various Chemicals in Ocean after they are Banned by EPA of US and Pertaining Chemical Regulatory Agencies of 1st World Nations. An Example Locally would Be DDT being dumped in the Waters near Cabrillo Beach in LA County, CA, US
This is the facets of the hard realities of Antropogenically created Oceanic Dead Zones with the Earth Changes of Mass Die-Offs of those that Swim, Fly, and used to thrive off the Sea.
Techno Solutions are an Oxymoron
There will need to be:
Disdain for Transgenically Gene-Modified Fish and Farmed Seafood.
or
Male Fish with Eggs in Testes due to Plastic and their Endocrine Disrupting Chemicals is Chemically induced Hermaphroditism that will be consumed by a Zombie Consumer Global Society.
Awakening to the Avariciously Leviathan-like nature of Overfishing via Industrialized Shortcuts such as Dragnets by Japanese and Spanish Fishing Fleets.
Lab Grown Meats and Seafood is a Franken-Farce like Soylent as a Meal Replacement.
Cold Raw Fish on Sweetly Soured Rice called Sushi and Pickled Ginger with a nasty little Additive to the Ginger itself might be the driver of high seafood consumption besides the Deep Fried fare that is Equally Popular.
Sushi and the Aspartame in that condiment of sushi called Pickled ginger is more to blame for the Overfishing due to sheer demand via the feeling the need to eat more sushi not due to sushi being "light not heavy food" but the Ingredient in Pickled Ginger that breaks down into the "Diabolical-Neurotoxin Trinity" of Formaldehyde, Phenylalanine(Toxicity via excess amounts disrupts serotonin levels in the Brain), and Aspartic Acid(Excitotoxin which Overexcites/Burns Out neurons in the Brain) which causes cravings for more Sushi.

I Vote Tillapia to replace Cod and Haddock.
Pick one you anthropogenic climate change shills: co2 or nuclear.. Cause solar and wind can never add up to the amount of energy that we use, not they can replace normal generation b because we don't have any reliable way of storing the huge amounts of energy that we use. Batteries, even lithium ion can't put a dent on it. I'm sick of that jerk off elon musk and his pseudoscience with the tesla wall crap. Ask a real power engineer you shill
