Claims that CO2 warming is causing oceans to loose oxygen is thoroughly examined and refuted. In truth, the increase in upwelling and marine productivity, supporting a robust marine ecosystem since the Little Ice Age , is responsible for changes in the volume of oxygen minimum zones. The loss of oxygen is due to the increased consumption of oxygen needed to digest and decay the increasing abundance of organic matter. The media’s headlines of a “de-oxygenation crisis” is simply profit seeking click-bait misinformation, while politicians and researchers seeking funding claim they have the solution to the non-existent crisis.

More CO2 = more plant life = more oxygen
I detest Carbon Cycle deniers!
Seeing as how we are carbon based, more CO2 is good for us animals and fungi.
The released oxygen comes from reducing water.
A sea water crisis is imminent!! It’s worse than we thought!
Wait… so sea levels are going to fall? I though they were supposed to rise.

I’m so confused.

No, less, but I wonder where it’s going? Wait, doesn’t CO2 dissolve in…never mind.

A true, but irrelevant fact.
One that everyone is already aware of.
Except Zig Zag Wanderer, that’s why I pointed it out.
It really is sad when Loydo tries to pretend he knows what he is talking about.
As I stated before true, but utterly unrelated to the point that ZZW was making.
Loydo
When any gas is in contact with water, some gas will dissolve in the water.
The amount that dissolves at a particular temperature depends on the pressure, or partial pressure, of the gas. The dissolved gas and the undissolved gas are in equilibrium.
But when when concentrations of O2, CO2 and temperature are all varying then it’s a complex situation.
What’s your considered opinion on how the situation in the oceans is changing when ocean temperatures are rising and we’re adding CO2 and reducing O2 atmospheric concentrations?
In my considered opinion you’re better off just looking at a few graphs.

Loydo still is unable to connect his fact to anything the rest of us are talking about.
Unless you are actually stupid enough to believe that higher CO2 levels in the atmosphere are the cause of these small drops in O2 levels in the oceans.

Try to tell us, how oceans are warming. CO2 ?? No
Sunlight ?? Yes
Himan climate change ?? No.
Once again you are trying to violate hundreds of millions of years of reality with fake nonsense.
During the most fertile period of life on earth (Cambrian Explosion )
co2 levels were almost 20* higher ,yet this was the time when the first fishes appeared, Einstein.
And the greatest increase in fish variety happened during the Devonian when co2 levels at their lowest were at least as high as they are now but most of the time much higher.
Neither have this co2 levels ever caused a runaway effect nor had they caused negative conditions for the fish – the exact opposite is true as it almost always is when the planet has more co2.
Blame fertilizers or pollution for lower oxygen but not co2.
How do you know these low-oxygen zones have not always been there?
The second map is “Change in oxygen content of the global ocean in mol O2 mā2 decadeā1.”
Jim’s “upwelling’ may well be contributing but a lower atmospheric conc. is probably also a factor.
I would have thought that surface water temperature and air temperature would have played a large part as well. Obviously you haven’t considered the change from warm to cold state of the AMO or PDO, not to mention the changes due to La Nina/El Nino conditions. Viewing one factor to the exclusion of all others is remarkably stupid and unscientific – look at everything that is happening with the oceans.
And there we have it, folks: Climate Scientology in a nutshell!
“I would have thought that surface water temperature and air temperature would have played a large part as well.”
I’m sure that’s right, I never said they didn’t.
“Viewing one factor to the exclusion of all others is remarkably stupid and unscientific”
My previous post included two possible causes, so why don’t go out for a walk and get some fresh air.
Once again, you are making the assumption that oxygen concentrations are static, which is obviously false. So you have no idea.
Um, no I posted evidence of it changing.
What evidence do you have that atmospheric oxygen concentration has declined recently?
I did the research for you, I provided a link to it for you. What, you want me to spoon feed it to you?
Nowhere in your links can I find any mention of atmospheric oxygen concentration changing.
To be fair to Loydo, the relevant link was provided above as:
http://www.astronomynotes.com/solarsys/pics/CO2-levels.png
The plot does not tell the whole story, however. The decline in atmospheric oxygen (data from Scripps O2 program expressed as Ī“O2/N2: see https://scrippso2.ucsd.edu/) is remarkably linear when plotted against atmospheric CO2 and reflects about 2.2 moles reduction per one mole increase in CO2 (terrestrial photosynthesis is about 1.1 in the opposite direction).
If the organic matter originates from carbon based life forms & increasing CO2 engenders more bio-mass then CO2 is an “abundance” factor contributing to “increased consumption of oxygen” in marine ecology. Maybe it’s not CO2 “warming” as Original Post points out, but we still get to implicate rising CO2 somehow.
Always look forward to your informative posts Jim. A minor concern is the video format as opposed to written contributions. I find written words easier to assimilate.
I agree Dnalor50, I always appreciate when a video is accompanied by a transcript.
I am now looking into how I can make a transcript of my videos
Jim, very much appreciated!
From now on I am generating a transcript for each video. The transcript for this video is now available at

If at first you don’t succeed, tell bigger lies.
The climate science motto.
Would you believe global warming is making sushi taste fishier?
Seems a bit fishy to me.
It’s making SOMETHING fishier, for sure.
A decade before the CO2 climate scam came along, people were hyperventilating about humans consuming everything on the planet. This was the basis of Paul Ehrlich’s and John Holdren’s carnival barking claims to fame. Oxygen depletion of course came up from its obvious use in the combustion of fossil fuels.
The preeminent scientist of the day (late 60’s, early 70’s) on this topic was Wallace “Wally” S. Broecker, of Columbia University, who passed away in February 2019. Wally Broecker popularized the term “global warming” as a possibility of adding additional CO2 to the atmosphere, even though the heat trapping effect of CO2 concept itself went back much further to Calendar and Svant Arrhenius.
Wally Broecker authored the attached essay (as an image) in Science Magazine, issue 26 June 1970:
I was little, but I remember a friend of my dad’s talking about this and him pointing out all the vegetation around that produce oxygen.
Joel, Great article to add here. In 1970’s Broecker was not only showing quantitatively why de-oxgenation will never be a problem, but he asked mainstream media to help dispel the de-oxygenation fear mongering of his time.
Sadly. in their quest for click bait profits, Lame-street Media has done just the opposite and intensified the far mongering
A short Google News Search on “De-Oxygenation Crisis” Turns up this headline from the World Economic Forum (WEF)
You can’t have a healthy planet without a healthy ocean:
Interview with UN Special Envoy for the Ocean.
where you will find this graphic and at the bottom is a chart for sea level. After some computer aided graphic eyeballing it looks like the lowest scenario SSP-1.9 is about 0.5 meters of sea level rise by 2100, or almost 6.3 mm/yr every year starting right now. Does anyone ever run those numbers when so many meters of sea level rise by the end of the century are tossed around?
Just remember, Maurice Strong a former Chairman of the WEF is quoted as wanting to bring about the collapse of industrialized civilization. And Christiana Figueres featured in a side bar at the bottom of the WEF article has been quoted as wanting to change the economic development model that has been reigning since the industrial revolution.
People in 1925 didn’t believe what was written in Mein Kampf* and look what happened. The world needs to wake up to the fact that the disciples of Marx are alive and well, but most importantly, they are busy.

That is about the diameter of a very large raindrop. And according to ‘experts,’ will result immediately in more severe flooding.
Loooooooooooose

Loose oxygen. Just the way I like my women.
Loose women are easy to lose….
If you met a tik-toker you couldn’t lose it quick enough.
As so often, the precise opposite is true.
Rising CO2 actually increases oxygenation of the deep ocean as showed by isotope data:
https://ptolemy2.wordpress.com/2020/10/14/atmospheric-co2-is-good-for-the-deep-ocean/
as shown
The oxygen has been taken by oxygen thieves. CO2 gets taken up by life.
Oxygen depletion does explain the lack of higher thinking by the Greens. Maybe if they quit holding their breaths in childish-anger their brains would start functioning again?
Saint Greta put a curse on you Robert.
No worries. No worries at all.

The good news is, if we’re going to a hydrogen-powered economy, then all that sea water that gets split for the ‘H’ will also provide lots and lots of ‘O’s.
–
The bad news is that we might need to make so much hydrogen that sea level will drop alarmingly.

**sigh** For worriers, there’s always something to worry about.

Keep an eye on the Chinese soot (Fe2O2 component) as a reason for increased ocean productivity.
Interesting… Would have to evaluate the ocean productivity downwind of any plant.
Every cloud has a silver lining.
