The Dangers of Underscoping Risk
In 4°C, Ruhl and Craig effectively argue that governance measures, particularly adaptation planning, will fall short if institutions fail to embrace the real possibility that the planet will blow well past 2° Celsius (°C) above pre-industrial temperatures. Further, they argue that 4°C is a better target for adaptation planning because this metric better captures the future risk the nation faces. Ruhl and Craig are keenly aware that serious talk of a possible 4°C future will almost certainly trigger accusations of “doomism” from various critics.
