Emeritus White's Professor of Moral Philosophy
University of Oxford
How should we respond to climate change? It is well recognized that this question raises important issues of justice over the distribution of burdens and benefits among different countries, which moral philosophy can help to settle. It also raises important issues of value, and these too fall within the domain of moral philosophy. How should we cope with the great uncertainty that surrounds climate change? Climate change will kill many people in many ways; how should we take account of these deaths in our planning? And how should we take into account the effects climate change will have on the world's future population? There is a very small chance climate change will even lead to our extinction. What can moral philosophy say about this?
