IPCC models are based on economic models that use faulty methodology (MER vs accepted PPP). In these, North Korea and similar basket cases will have a GDP 2x that of US in 2100.
These are base models.

All subsequent models use these faulty initial economic models.
Most use RCP 8.5 (worst case emissions and forcing models). This is a likely IMPOSSIBLE scenario, as it assumes using several multiples of current coal reserves, at low prices, with little tech innovation.
