Sorry if this sounds like a dumb question, but I legitimately don't know: does the thermodynamic argument hold up? (Broadly, I agree that humanity needs a healthier relationship with industrialism before fixing this is possible).
A few ways I can imagine it doesn't:
- We can reduce warming by other means, like changing the Earth's albedo.
- A lot more energy falls to Earth every day from the sun than we use via petroleum; a good amount of solar/wind would let us climb back up the hill via sequestration.
- We don't need to sequester CO2/methane into high-energy-density hydrocarbons; could an efficient sequestration process yield eventually net positive energy per unit greenhouse gas from the burn -> sequester process?
