Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Well, it's a demonstration of hydrogen utilization. And if it spares ice vehicle trips, it's just fine.
I see what you did there.
Please do explain how is less harmful to drive in a diesel tractor around.
This sounds almost like tractors are born in a shed, not made in a factory.
Not so much and less with newer battery types
Again, see first comment. Out of curiosity, what are coal-burning factories anyway?
While tractors are relatively cheap, you fail to see all the disadvantages with them it seems. Like fuel grows in a fuel pump stations and I'm sure they are very beneficial to air you breath, not counting co2 emissions and many other negative aspects. Let's do a test. I'll lie down next to e-vehicle exhaust and you'll do the same next to a tractor exhaust or any other ICE vehicle of your choice. Let's do that for 5 minutes while engines are running.
And how are we doing with consuming less? Oh, wait, I know - consumption of oil and coal is at all time high.
Nah, not very fine. I wonder if it could be less eco-friendly to run something like this over an ICE car simply due to the massive energy demands of such a vehicle and the losses on energy to hydrogen to energy conversion.
Flying transportation is only reasonable at a large scale and high speeds, which is not a characteristic of an air taxi.
Also, better use hydrogen-powered car then.
While hydrogen is expensive to produce, it can be produced from reusable sources or surplus energy which makes it way cheaper and way cleaner. Also solves energy storage. A side note: ICE is around 20% efficient. I'm also sure that flying in choppers and private jets is not that clean and efficient. And yes, cars would be better, but both can coexist.
True, but that would require building expensive infrastructure that would sit idle for most of the time while we wait for the surplus - assuming we talk intermittent renewables.
Sure enough, hydrogen fuel cell is cleaner than ICE, my objection was to the form of transportation that might require so much power an ICE car would be a better alternative (but not an ICE air taxi, to be clear)
From an ecological perspective, they can not, and that's what this "invention" pretends to be about. Also, cars too are far from perfect, but at least better than this monstrosity
