As I understand it, this scenario excludes the interplay between games in mitigation and games in geoengineering.
Present political debate around GE is highly affected by the interplay. Indeed, it could be argued that this interplay is the central factor in current debate. The simplifying assumption used by the authors therefore applies only in a decarbonised world, and is thus inapplicable to all near-term scenarios. Therefore, a more realistic model is that of torture. For example, the UK has a history of posturing against torture, whilst tacitly and deeply co-operating with states that torture - in both the practice of torture and the utilization of intelligence gained by torture. We should expect similar double-standards from developed nations with an active environmental lobby in the case of GE.
