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.

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
