The objectives of this project are:
1. To examine policy decision making under conditions of severe uncertainty: situations in which we lack complete information about the probabilities of possible future states of the world, about what actions will be available and what their outcomes will be, and about the desirability of these outcomes.
2. To study scientific models that are both imperfect and non-linear, especially those of the climate and of climate change, with a view to:
(i) understanding what limits they imply on our ability to generate forecasts that can be used by policy-makers; and
(ii) investigating ways in which such models can be fashioned to provide policy-relevant information.
3. To study the implications for climate policy-making of the inherent limitations we face in making predictions about relevant climate variables, in relation both to our ability to assess the impact of possible interventions and to our ethical assessment of them, and to propose techniques for dealing with these limitations.
4. To develop philosophical expertise in the field of decision-making under severe uncertainty by providing doctoral training and supervision.
The project was initiated with a large AHRC grant (running from March 2013 to March 2016) and now carries on with funding from CPNSS. It is carried out in collaboration with economists and climate scientists in other departments at LSE (and elsewhere).
