The geography of geoengineering


IN DISCUSSIONS of climate change it is an article of faith that there are no winners, only losers. This is in part an expression of bien-pensant solidarity, but it is also realistic. It recognises the degree to which current human arrangements—farming practices, positioning of cities, etc—are adapted to current climatic conditions, and that shifts in those conditions will impose transition costs even if not in absolute terms dreadful. It also acknowledges the world’s ever greater level of interdependency. If the local effects of climate change in Syldavia, say, are pleasing to the residents, those benefits can still be offset by a loss in trade with the much worse affected Ruritania, or through conflict over water resources with now-parched Borduria, or by influxes of refugees from Vulgaria, and so on.
