It’s frustrating, as there are options that could be scaled given enough support. But we don’t want to subsidise it, as there’s not enough short-term profit for investors. I suppose there’s some sense in that given other areas are far more polluting, but it seems short-sighted to not subsidise the uptake of potentially game changing technologies.
Although here’s your regular reminder that the fossil fuel industry received over $1 trillion of subsidies globally in 2022, the highest on record, despite the industry making record revenue of over $4 trillion. |  |

To add to your point- over half of global fossil fuel production was produced by state owned energy companies - in such cases tax payers are directly funding the capital for E&P. Norway are still handing out licenses for artic exploration to their state owned Statoil. |  | | |

That is the problem. To get a big aircraft (plus payload) a long distance requires a lot of fuel. It's just the laws of physics.
Much more efficient than it used to be, with modern high-bypass turbofan engines, but still massive consumption in absolute terms.
That's without considering the issue of particulate pollution in the upper atmosphere. |  |

We need a flying car. Piloted by a drunk. ham sandwich-eating fox. |  |

It will be interesting when the inevitable where are you going for your holiday threads appear on here over the next few weeks.
Plenty talk a good game but don't want to give up their lifestyle.
Not aimed at you OP or anyone specific. |  |

Indeed. I haven't flown for nearly ten years now, and I suspect I probably won't fly again. But I'm not sure I won't be tempted to put a bag over the old conscience and nip off to somewhere hot.
We don't do principled selfless action very well. |  |

Are there really options that could be scaled without massive impacts on other environmental issues though? Biofuel or waste-generated fuels are fine in principle, but how much do you need and what natural ecosystems or farmland do you destroy to create even a fraction of what would be required to lift hundreds of thousands of tons of aircraft every day to 10km, shift them across the world, and put them down again?
I don't know the answer or whether my estimate of mass are remotely close, to be honest. | |

Tech bros and market dynamics will save civilisation, you just need a little faith.
Seriously though, I wonder how exposed the financial sector is to the impacts you talk about. I've seen pension funds that claim 5C of warming is a risk they can manage and is based on the models built by economists that assumes ergodicity and find optimal warming of 3-3.5C. A recent paper calculated GDP out to 2100 to four significant figures - just ludicrous nonsense. It is no wonder that impacts are likely to hit earlier than people expect as these 'experts' have told them there is little to worry about in this half of the century.
If the financial sector collapses again, the funding for the tech bros, energy transition and adaptation are likely to stall. This would hugely impair our ability to build resilience for the worsening impacts. |  | | |
