The future of utilitarianism

My recent work has focused on the demands of utilitarianism, and our obligations to future people. In my current work, I draw on that earlier work, and ask how utilitarians might deal with the ethical challenges of climate change. Climate change has obvious practical implications. It will kill millions of people, wipe out thousands of species, and so on. My question in this paper is much narrower. How might climate change impact on moral theory — and especially on the debate between utilitarians and their non-utilitarian rivals?
