Good luck…we can’t even get companies to stop poisoning drinking water for entire cities…you won’t stop Elon from doing whatever he wants when he and his buddies can just buy new laws.
Ozone is something where we’ve gotten big changes like that before.

How about we wait until the science is actually in before kneejerking around? We have had the science equivalent of a shower thought, actual work and analysis needs to be done before jumping to conclusions.

How about we wait until the science is actually in before sending hundreds and thousands of satellites into LEO?

NOAA is doing this science and is alarmed, this isn’t just some shower thought
Using an extraordinarily sensitive instrument custom-built at NOAA in Boulder, Colorado, and mounted in the nose of a NASA WB-57 research aircraft**, scientists found aluminum and exotic metals embedded in about 10 percent of sulfuric acid particles, which comprise the large majority of particles in the stratosphere. They were also able to match the ratio of rare elements they measured to special alloys used in rockets and satellites, confirming their source as metal vaporized from spacecraft reentering Earth’s atmosphere.

There will be a lot of work to understand the implications of these novel metals in the stratosphere,” Murphy said
I don’t see anything in that article about them being “alarmed”.
So far all the scientists appear to be saying “heads up, we need to investigate this further”, not “stop launching, this is bad”. We should listen to the scientists.

if you read the linked pnas article at https://www.pnas.org/doi/10.1073/pnas.2313374120 while remaining scientifically dispassionate I very much get the impression they are trying to warn us about the trajectory we are currently on.
You are correct though, the article doesn’t say that they are alarmed I have inferred that from following the subject in general.

Let’s fire some shit in the atmosphere first and then let scientists figure it out when it’s too late anyway. Absolute boomer shit

Methane is CH4. When it burns, it turns into Carbon (NOT carbon dioxide) and Hydrogen.

Have yet to see any of these ‘studies’ take into account and compare with natural meteorite effects, which are orders of magnitude larger than the satellites.

Niobium and hafnium do not occur as free elements in nature, but are refined from mineral ores. They are used in semiconductors and superalloys.
In addition to these two unusual elements, a significant number of particles contained copper, lithium and aluminum at concentrations far exceeding the abundance found in meteorics, or ‘space dust.’ “The combination of aluminum and copper, plus niobium and hafnium, which are used in heat-resistant, high-performance alloys, pointed us to the aerospace industry,’’ Murphy said.
they are finding elements that don’t even occur in nature, and elements that do occur but in proportions in the atmosphere that have grown significantly since we started burning up rockets.
Armchair scientists don’t seem to give actual scientists much credit.

Best be hoping Tesla collapses and Elon gets his with the SEC. When TSLA falls, he will lose his connections and no one will be willing to protect him, just another loser millionaire white guy and sometimes the government does go after them.
Elon will likely be fried at that point because he will have committed the worst crime in America: messing with rich people’s money.

Of all the valid reasons to hate elon for, this is not one of them. The emissions from the entire world’s satellite re-entries are basically nothing on an atmospheric scale.
- Hirom ( @Hirom@beehaw.org ) 4•3 months ago
The article cite a peer-reviewed scientific paper which indicate satellites reentry has a significant effect.
Have you published (or know of) a better research paper that show this is incorrect?
the population of reentering satellites in 2022 caused a 29.5% increase of aluminum in the atmosphere above the natural level.
[…]
As aluminum oxide nanoparticles may remain in the atmosphere for decades, they can cause significant ozone depletion.
There article is about a paper showing that there’s a significant increase in aluminum oxide in the atmosphere. The particulates from that are part of how the small amounts of chlorine in the atmosphere are able to destroy ozone.

https://phys.org/news/2024-06-satellite-megaconstellations-jeopardize-recovery-ozone.html
When old satellites fall into Earth’s atmosphere and burn up, they leave behind tiny particles of aluminum oxide, which eat away at Earth’s protective ozone layer. A new study finds that these oxides have increased 8-fold between 2016 and 2022 and will continue to accumulate as the number of low-Earth-orbit satellites skyrockets.
Those micrometeors aren’t mostly aluminium.
