Trouble is that carbon-neutral flights are possible, but they're decades away. There is not way in which we meaningfully limit climate change that doesn't come with a radical change (reduction by most measures) in the quality of life of your average 1st world resident.

How do we change decades to months? Pretty sure it’s possible if we invest in it. Look at rocketry or nukes in the WW2. We need that kind of focus and investment.
