Abstract

Climate change is a moral problem. The main reason to reduce greenhouse gas emissions is a concern for faraway lands (Schelling 2000), distant futures (Nordhaus 1982), and remote probabilities (Weitzman 2009). The people who emit most are least affected by climate change, and the benefits of their abatement would be diffused. Carbon dioxide dwells in the atmosphere for decades and the effects on temperature and sea level play out over even longer periods. On central projections climate change and its impacts are a nuisance for rich countries and a problem for poor countries. But there is a chance that things will go horribly wrong. If you do not care about risk, the future, or other people, then you have little reason to care about climate change.
