Climate change and global warming scientists seeking grants for continuing research use computer model simulations to fabricate justify why they need more budget monies from the government - it is a constant doomsday whining that inflicts (and impacts) the entire science community.
The latest simulated calamity that is being tossed around as a doomsday scenario has the oceans being depleted of oxygen because of CO2, thus making marine life impossible.
As with all computer climate simulations, this is junk science that policymakers and the public have no need for. It's a disaster-distraction used to pretend that "scientists", with just a little more money (but always turns out being a whole lot more), will be able to quantify doomsday from natural climate reality - not very likely.
“Since oxygen concentrations in the ocean naturally vary depending on variations in winds and temperature at the surface, it’s been challenging to attribute any deoxygenation to climate change."
Objectively, this certainly appears to be just another case of ever money-desperate climate science sucking the oxygen out of all other scientific endeavors.
Because, if it ain't ocean acidification that will kill of marine life, then for sure it's gotta be the speculative oxygen starvation that does the job, donchaknow!

Scientists know that a warming climate can be expected to gradually sap oceans of oxygen, leaving fish, crabs, squid, sea stars, and other marine life struggling to breathe. This is absolute rubbish Year ………. Feb ………. Aug Ocean temperature from February to August in 2014 goes up by nearly 5C: Ocean August temperature from 1860 -2014 (154 years) changed by 0.7C |
Guess all the oceans died during the Medieval Warm Period and the rest of the 95% of the earth’s history when temps were higher.

O2 from ocean based photosynthesis is estimated to be around 50% of total O2 production. More CO2 in the water means more biomass which means more O2. Good thing, considering we need O2 just like plants need CO2. Win, win. |
02 flux has actually varied (15% to 35%) throughout millions of years of geological time. We are currently near the middle of this range. Here is a good summary of disparate causes and observations… http://r.duckduckgo.com/l/?kh=-1&uddg=http%3A%2F%2Fwww.pnas.org%2Fcontent%2F96%2F20%2F10955.long |
So in other words. Their model that was program to show CAGW causing oxygen depletion, shows oxygen depletion. Wow! That is about as scientifically important as the fact that turning on my oven causes it to heat up. A model will do what it is program to do. The important thing is does the model react the way the real world does. Did they verify any of their model output with actual real word data? If not they should be forced to pay back all the money they got and have their degrees revoked. |
Sigh – good thing we are still well within the natural variation that already happened since the end of the last full on ice age (we are still in an ice age). It’s been warmer, quite a bit warmer, 5 times since then. Everything survived and we are still swamped by past natural variation. Only hubris in the guise of models creates the panic to drive political change or simply grant money. |
More garbage from people that have never taken an oceanography course or picture the ocean as, “it’s just there” and refuse to believe that it is a dynamic environment we do not understand! We know more about the moon than we do about the ocean. So to “conclude” that lower O2 levels will become detectable in….wait for it….yep 20 years time is absolute rubbish. Why is every doom and gloom prediction on a 20 year scale? Has anyone ever asked that question? Maybe they should. |
