In this paper I show that the definition of convention offered by david lewis in his book "convention: a philosophical study" fails to shed much light on "our common, Established concept of convention." first I set out lewis' definition of convention. I then show, Via counterexample, That satisfaction of lewis' definition is not a necessary condition for something to be a convention. I also show via counterexample that it is doubtful that satisfaction of lewis' definition is a sufficient condition for something to be a convention. I conclude that lewis has invented a new concept of convention that is seriously at odds with the established concept of convention

In recent years the idea of geoengineering climate has begun to attract increasing attention. Although there was some discussion of manipulating regional climates throughout the l970s and l980s. the discussion was largely dormant. What has reawakened the conversation is the possibility that Earth may be undergoing a greenhouse-induced global wamring, and the paucity of serious measures that have been taken to Prevent it. ln this paper Iassess the ethical acceptability of ICC, based on my impressions of the conversation that is now taking place. Rather than offering a dispassionate analysis, I argue for a point of view. I propose a set of conditions that must be satisfied for an ICC project to be morally permissible and conclude that these conditions are not now satisfied. However, research on ICC should go forward..
