      abstract = {The potential of geoengineering as an alternative or  complementary option to mitigation and adaptation has  received increased interest in recent years. The scientific  assessment of geoengineering is driven to a large extent by  assumptions about its effectiveness, costs, and impacts,  all of which are highly uncertain. This has led to a  polarizing debate. This paper evaluates the role of Solar  Radiation Management (SRM) on the optimal abatement path,  focusing on the uncertainty about the effectiveness of SRM  and the interaction with uncertain climate change response.  Using standard economic models of dynamic decision theory  under uncertainty, we show that abatement is decreasing in  the probability of success of SRM, but that this relation  is concave and thus that significant abatement reductions  are optimal only if SRM is very likely to be effective. The  results are confirmed even when considering positive  correlation structures between the effectiveness of  geoengineering and the magnitude of climate change. Using a  stochastic version of an Integrated Assessment Model, the  results are found to be robust for a wide range of  parameters specification.},
