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.
What would be the closest “we’ve got to change or perish” moment we’ve successfully navigated?
“Plasma Tunnels Reveal How Dying Satellites Fall to Earth” (ieee.org)
I.E. avoiding population collapse due to lack of ecosystem carrying capacity? Eliminating famine? etc.
Banning CFCs perhaps?
If you want to go older and more localised you could look at forestry and fisheries laws. Sometimes we self-regulate and form a stable state, other times we over-extract until collapse
It is possible for us to work together and fix these things.
Edit:
Moving away from leaded gas might be another example.
(CFCs and leaded gas invented by the same dude, fun fact: https://en.wikipedia.org/wiki/Thomas_Midgley_Jr. Quite a legacy...)

Climate change has been the story of evolution since life appeared on earth and aglae filled the atmosphere with gasses.
> Climate scientists can raise the alarm or whatever but have no credibility
Climate scientists have credibility.
Seriosly? Imo they never recovered it since the "hide the decline".
What would you do if you studied this matter for several years, and found overwhelming evidence that this is such a category of problem?
If you don't know, maybe you should look it up instead of touting your ignorance in a public discussion forum? Your ignorance is not noteworthy. And while you're at it, you can educate yourself on climate change and proposed solutions to it, too. You seem to be suffering from several significant misconceptions, likely because you're bought into a narrative spun out by political hacks with zero understanding of the relevant scientific principles/knowledge and a vested interest in never changing that.
Please make an effort to engage more substantially with reality, especially on this forum.
Absolutely ridiculous. Climate scientists have credibility; climate science denying cranks who blather about communism have none.

Muted via my HN front end ... I won't be responding further.
Also, it's important to realize that climate change, as we best understand it right now, is not a "or perish" type of situation. RCP8.5 has now been soundly eliminated from the set of potential climate trajectories, so what we're left with is a question of 1) how much mass migration will be forced upon the world, with concomitant wars and social strife, and 2) how much economic loss results from that, as well as from lost opportunity by not adopting cheaper renewable energy routes.
Technological innovation has done something absolutely remarkable: the future with the cheapest and most abundant energy is the one that switches to renewable energy and storage the fastest. Every day we delay, not only do we end up with a worse climate outcome, but we also just light money on fire, with worse economic efficiency. And in economies built on the continual compounding interest of technological advancement, we subject humanity to far greater poverty for every day we delay the transition.
Most of the world will benefit from this technological change happening quickly. There will be some outliers, like the US, that choose to be poorer and less influential by actively subverting renewable energy in the marketplace (the Trump administration has done a huge amount of economic damage in only a small amount of time), but the US will come around. Texas is leading the way, because they are actually market driven more than they are politically driven, but the rest of the US is kind of screwed on that front for a while.
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?
I'll pick on the US, because blaming India and China will incite their little public defenders to bury the thread.
The Gulf of Mexico is currently downstream of the US's crop production which dumps nitrogen and phosphorous into it, which is bad and causes problems like the article attempts to illustrate.
As you should. The current administration is partially owned by the fossil fuels industry and is literally paying to destroy existing and planned renewable energy sources.
The agricultural runoff problem is an ecological crime scene. We could solve it if we weren't so corrupt.
The point is being deranged about the current admin doesn't help the scenario. Every team (political group) fucked up royally, continues to fuck up, and only cares about how much money businesses are putting into their second home or their kid's trust fund.
There is no hope unless we decide to do things globally. And until you are willing to "compel" countries who don't play along, it's not happening.
So, no, shaming people or telling them to be afraid will not help.
who could have thought, eh?
It's real, and documented: https://mississippiriverdelta.org/learning/explaining-the-gu...
If it's a thirst for librul teers, sorry to disappoint you.
This is normal. This is how our Earth the planet works.
I do not know why you think only aerobic biota has a divine right to live.
Do you now feel yourself not completely intellectually honest?
For example, I clicked on the random link in that paper (referenced as a proof of river oxygen decline) — the article was not even based on some actual data log but fucking deep learning model (which may or may not work)

Do you think climate change wipes us out before some other natural disaster?
