Zusammenfassung: 
Let there be a positive (exogenous) probability that, at each date, the human species will disappear. We postulate an Ethical Observer (EO) who maximizes intertemporal welfare under this uncertainty, with expected-utility preferences. Various social welfare criteria entail alternative von Neumann- Morgenstern utility functions for the EO: utilitarianism, Rawlsianism, and an extension of the latter that corrects for the size of population. Our analysis covers, first, a cake-eating economy, where the utilitarian and Rawlsian recommend the same allocation. Second, a productive economy with education and capital. There, however, the recommendations of the two Ethical Observers are in general different. But when the utilitarian program diverges, then it is optimal for the extended Rawlsian to ignore the uncertainty concerning the possible disappearance of the human species in the future. We conclude discussing the implications for intergenerational welfare maximization in the presence of global warming.
