alt Hacker NewsUnderwater oxygen loss threatens earth's stability, researchers warn
Comments
Have we ever as a species successfully changed our behavior on a scale needed to address something like climate change and underwater oxygen loss?
What would be the closest “we’ve got to change or perish” moment we’ve successfully navigated?
As the link is university press release, here is study mentioned: https://aslopubs.onlinelibrary.wiley.com/doi/full/10.1002/ln...
Oxygen loss already happens, see news about dead fish.
Issue here is that becomes more common and underwater oxygen loss is approaching an “unsafe space” with impacts likely irreversible within human lifetimes, some of which could persist for centuries.
Coastal “dead zones”, impact of fish food etc.
"Irreversible on human timescales" is a nice succinct wording; I think I usually end up discussing that concept in a less clear / more roundabout way.

It's almost like we might need that network of oceanic data collection sites.
The one recently defunded by the Trump administration.

Go team!
The feedback loop between warming and deoxygenation is particularly concerning for deep-water systems that have been stable for millennia. If we hit the thresholds mentioned where the ocean's 'internal clock' is disrupted, it might permanently alter nutrient cycling beyond what current atmospheric models predict. I'm curious if any researchers here have insight into whether localized aeration tech could mitigate this in crucial spawning grounds, or if the scale is simply too vast.
Next post would be what: Human hubris as measured by UN Hubris Measuring Commitee now threatens to collapse the entire solar system into a purple hole?
Can we please snap out of it and use something like if not common sense but at least a Fermi approach? Or did he die in vain?
“Threatens earths stability”
So do nukes. Or a series of earthquakes. Or a really bad set of solar flares. Or a world war.
This just in, death threatens life. The internet sucks.
Oxigen is ALSO, and perhaps in vast quantities produced at the bottom of the ocean, by lumps of metal that react with sea water (aka Dark Oxygen). Interestingly, there are now massive marine harvesting operations targeting that very ore.
