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?

CFCs are responsible for the ozone hole. There are no known significant natural sources of CFCs. The ozone hole was caused by humans and its course correction was due to the political will to phase out CFCs.

Climate scientists have credibility.

It's been a known issue since the 1980s. LUMCON/Rabalais, Farm Bill in 1995, 1997 Hypoxia task force, 2001 Action plan, 2008 Action plan, 2011 Stoner Memo... 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.

This admin is detaching from democracy and encourages a fact-free world. We will need those to fix climate change.

Are there actual measurements that even show this deoxygenation? 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) https://www.nature.com/articles/s41558-023-01793-3

Yes, the organization I work for studies this phenomenon extensively. We measure pH, temperature, oxygen, flow, and many other factors related to ocean health, and over time, climate change. Hypoxia (and acidification) are emerging concerns.

> Things like this, it’s still hypothetical. Climate scientists can raise the alarm or whatever but have no credibility, certainly not when the proposed solution is some kind of global authoritarian communism, and it always is.

Absolutely ridiculous. Climate scientists have credibility; climate science denying cranks who blather about communism have none.

Things are really bad.

Muted via my HN front end ... I won't be responding further.

Ozone hole over Antarctica. 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...)

When the costs are low and require no change in personal behaviour, nor even belief in the problem. Billions of people had no idea about changes to aerosol propellants or refrigerants and they were not required to know or agree in order to solve the problem.

Do people have to know about what generates their electricity? They get input now, but we could probably just stop taking public input on new infrastructure and that would avoid poorly motivated protests of wind farms or nuclear.

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.

Yeah, sure. Meanwhile pollutants and CO2 per person have been on a downward trend for decades. But two years of this admin has ruined in all? 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.

We did a reasonable job with ozone depletion, but that has much lower costs. https://en.wikipedia.org/wiki/Ozone_depletion

Acid rain as well.
