Average person 40% poorer if world warms by 4C

*Average person will be 40% poorer if world warms by 4C, new research shows.* Experts say previous economic models underestimated impact of global heating — as well as likely ‘cascading supply chain disruptions’.

If they have estimated well the effect of those cascades, maybe this estimate will be on target. But I doubt that is even possible. With globalized production, it is easy for even a local disaster to make a crucial component totally unavailable for years. Maybe there would be no new computers, or no new cars.
