Climatologists have recently introduced a distinction between projections as scenario-based model results on the one hand and predictions on the other hand. The interpretation and usage of both terms is, however, not univocal. It is stated that the ambiguities of the interpretations may cause problems in the communication of climate science within the scientific community and to the public realm. This paper suggests an account of scenarios as props in games of make-belive. With this account, we explain the difference between (...) projections that should be make-believed and other model results that should be believed. (shrink)

In this article I propose to explore two issues. The first concerns what kinds of contributions academics can make to reducing poverty. I argue that academics can contribute in a number of ways, and I seek to spell out the diversity of the options available. I concentrate on four ways in which these contributions might differ.My second aim is to outline some norms that should inform any academic involvement in activities that seek to reduce poverty. I set out six proposals. (...) These concern: (1) the need to construct coalitions among people with different ethical frameworks; (2) the value of constructing nonideal theory on the basis of our best understanding of an ideal world; (3) the need for integrated analysis that connects antipoverty initiatives to other areas of moral concern; (4) the vital importance of interdisciplinarity; (5) the need for epistemic modesty and revisability; and (6) the need for accountability.

Here I argue that the hyper-individualistic and rationalistic ethical paradigms – originating in the late eighteenth century and dominating moral philosophy, in various permutations, ever since – cannot capture the moral concerns evoked by the prospect of global climate change. Those paradigms are undone by the temporal and spatial scales of climate change. To press my argument, I deploy two famous philosophical tropes – John Rawls's notion of the original position and Derek Parfit's paradox – and another that promises to (...) become famous: Dale Jamieson's six little ditties about Jack and Jill. I then go on to argue that the spatial and especially the temporal scales of global climate change demand a shift in moral philosophy from a hyper-individualistic ontology to a thoroughly holistic ontology. It also demands a shift from a reason-based to a sentiment-based moral psychology. Holism in environmental ethics is usually coupled with non-anthropocentrism in theories constructed to provide moral considerability for transorganismic entities – such as species, biotic communities, and ecosystems. The spatial and temporal scales of climate, however, render non-anthropocentric environmental ethics otiose, as I more fully explain. Thus the environmental ethic here proposed to meet the moral challenge of global climate change is holistic but anthropocentric. I start with Jamieson's six little ditties about Jack and Jill.
