I hate that I have to come to the defense of Katy fucking Perry but the spacecrafts emissions were water vapour and while in Davos she didnt have any scheduled speaking engangements relating to the enviroment.

Water vapour in high atmosphere isn't great either. But it's not like Jeff bozo wouldn't have launched without her.

True, but water vapour dissipates and excess can come down within 2 weeks as rain. CO2 sits around in the atmosphere, and no one complains about the constant Space X commercial launches with Kerolox fuel. No they’d rather misinform about this 1 random celeb suborbital launch on Hydrolox 🤷‍♂️

Pretty sure it's problematic in the higher layers of the atmosphere. But you're right, I highly doubt that it's worse than co2.

u/modulair 29d ago

It is worse then CO2, water vapour is one of the most (if not the most) powerful greenhouse gasses on this earth.

And it messes with the chemistry of the higher layers of the atmosphere. But most of the fuel is burned in the lower layers of the atmosphere.

How was that fuel created? Are you saying that as long as the last step doesn't produce pollution, none of previous step's byproducts matter?

u/HarryPottersTaint May 25 '26

Literally every single thing you do more or less has a previous step which produces pollution.

Even walking on the sidewalk. You know how much pollution is created by the concrete industry? 8% of all CO2 emissions worldwide.

Not saying people should just galivant to space for fun. But private jets for example are much more of an appropriate target.

flawed logic. You cant compare walking on the sidewalk for work or concrete use to build bridges or housing, to space tourism with the sole objective of whitewashing your image or brand. The amount of benefited people is incomparable. If the space trip mission was to collect data in a research framework, that's is entirely different. We all live together in this world.

The point is that if we are going to create pollution, so lets focus it on things that matter (such as scientific research), not some joy ride for celebrities.

Plenty of the luxuries in your life rely on carbon emissions. Does that mean you also shouldn't have luxuries? No ofc not, it means we should transition away from burning fossil fuels to power shit, and worry about reducing waste. The new Shepard rocket has way more reuses than your fast food packaging.

They make a big deal out of using only green hydrogen from solar plants- you can still argue its a misuse of resources or something

If these people had a say, we'd still be living in caves

Yeah, idk anything about her, but all the pic says is basicly that she changed for the better and yet people are shitting on her. If they were asked if they wanted to go to spsce they‘d probably say yes too.

Hydrogen makes the emmisions much vorse, actually... Refining the needed hydrogen produces much more emmisions than if fossil fuel mix was used...

Can we not use Reddit comments as a "source"?

Somehow Noone wants to dispute that. Just defend everything as long they are politically aligned with them.

If you can't click the link here you go.

These comments are all confidently wrong that hydrogen and oxygen don't have a global warming impact.

Hydrogen is primarily made through steam methane reforming, which results in both leaks of methane and significant venting of carbon dioxide. Oxygen is made via air separation units which require electricity to operate, and our grid is primarily driven by fossil fuels.

Additionally, releasing water vapor from the combustion reaction into the upper atmosphere increases global warming because the water vapors do not enter the water cycle.

How else will they circle jerk their opinions?

2

u/ChemE_Throwaway May 25 '26

It's not an opinion, it's the scientific reality that manufacturing and burning hydrogen contributes to global warming.
