A corolla is better for the environment than a Prius.
https://www.theguardian.com/football...-electric-cars
TL,DR version below :
But what about the environmental effects of building the car?
A report by the Ricardo consultancy estimated that production of an average petrol car will involve emissions amounting to the equivalent of 5.6 tonnes of CO2, while for an average electric car, the figure is 8.8tonnes. Of that, nearly half is incurred in producing the battery. Despite this, the same report estimated that over its whole lifecycle, the electric car would still be responsible for 80% of the emissions of the petrol car. More recently, an FT analysis used lifecycle estimates to question the green credentials of electric cars, especially heavy ones.

There are just several practical/economic problems with liquid H2...
It's corrosive as heck, if you understand chemistry well it will happily function as a reducing OR an oxidizing agent.
It's explosive as heck (google "challenger").
It needs to be kept cryogenic as heck.
Also it's not very dense, so would take up a lot of volume compared to kerosene. Would need a custom-designed plane for the volume and cryogenic fuel storage, and might have to give up belly cargo for fuel volume. Just a SWAG but I think the fantastic specific energy would offset the weight of additional structure for fuel volume.

Maybe they’ll develop cleaner batteries but each leap in technology features increasingly dirtier elements. China has admitted real environmental catastrophe associated with these activities.
Kind of like quitting smoking then shooting yourself in the foot. Are you really better off? Maybe...I don’t know.

Source? Why are you so convinced she is a prop? Is it really impossible that someone can be a well-informed, well-spoken person as a teen?
I also disagree that her "disability" and general cuteness affords her some kind of immunity from criticism. That doesn't really make sense considering how controversial she has become and the level of ire she's drawn from some segments of the political spectrum.
And, in any case, tuning someone out simply because they happen to be young isn't all that fair either. They are the generation that has the most to lose from inaction, but their voice shouldn't matter? I think you underestimate young people here.

Her trans Atlantic crossing and the facts behind it turned off the now rational people.

As others have said, you're wrong.
In any case, this is a complete red herring and has nothing to do with the issue. So what if she has aspergers? You can't refute anything she's said, so you make up half truths and lies to try and undermine her credibility because you can't offer any factual reason to disagree. What a sad and pathetic person you are.
That teenage girl with "severe autism" has more intelligence and poise than all these grown ass adults foaming at the mouth because she's pointing out uncomfortable truths.

Yeah seriously what “facts” has she actually brought up. When someone can explain to me why the ice glaciers melted to become the Great Lakes and how Holland has water rising thousands of years ago just as Miami continues today, before there were humans sala long the earth, than I’ll listen. Until then, I’m chalking it up to the earth changes when it wants to and our CO2 emisiones have very little effect. If anything, more CO2 is helping the trees anyways

And CO2 is good for sodas too !
I find it so ironic that pilots make fun of those chemtrail/flat earth idiots (and rightfully so!) and yet a good portion of said pilots, usually well educated and emotionnally balanced people, brush off 99% of the scientific community with the same thought process than conspiracy people mentionned above...
Actually, I dont know if it's ironic or really depressing.
Also, there is no so-called "Lift" on a wing, it's only invisible elves that push on the bottom of the wing with a broomstick.

I don't think most people here brush off the scientific community but people with a political stake in climate change have been fear mongering and crying wolf for decades and it grows tiresome. It's especially transparent when sensible people who propose nuclear energy as a way of reducing carbon emissions are shunned by the same group of people who claim to support science. It's a political issue, that's why you have differing opinions and not consensus.
Nuclear fission can be considered a stop-gap measure, within 20-200 years it's essentially inevitable that fusion and/or large scale space-based solar will be viable. The former sooner, the later not-so-soon.
If carbon is really THAT big of an issue, it should be worth dealing with some fission waste for a few decades. We've been doing it for about 70 years anyway, in many nations.
Greta and OAC can get back to me when they get onboard with that, and stop talking about shutting down airlines (and the entire economy) by 2030.
We do have to be fair, hard-core lefties are not the only impediment to paradigm shifts in the energy sector, I'm sure the petroleum lobby is paddling furiously to protect their interests. Hopefully they're smart enough to start working on synth/bio fuel soon, they are best suited infrastructure-wise to doing the heavy lifting on alternative liquid fuels.
Also have to recognize that ending the petroleum production industry will have far-reaching economic consequences as well, but probably not as bad as grounding all the jets. A lot of folks are employed in oil production, and some regionas (including Alaska, Canada, and several US states) would be destitute. Some of that will be mitigated by alt liquid fuels but most pax cars will end up on batteries, or with part-time hybrid and a fuel tank that only gets used on long road trips. Liquid fuel would probably be reserved for applications where the energy density of batteries won't cut: Jets, large trucks, ships, some heavy equipment, and weapons systems.
