Abstract
Arguments in environmental ethics often appeal to information from environmental science, such as information about the causes of environmental problems. Contemporary work in philosophy of science can shed light on the practice of environmental science as well as some of the challenges it faces. This chapter surveys some of this work, focusing on three interrelated topics: the nature of scientific evidence, including connections with uncertainty and consensus; the use and evaluation of scientific models; and values and objectivity in scientific practice. A better understanding of these topics can help to ensure that scientific information is used appropriately and effectively in ethical argumentation.
