We construct novel proxies of aggregate physical and transition climate risks by conducting textual analysis of Reuters climate-change news over 2000-2018. This analysis uncovers four textual risk factors related to the topics of U.S. climate policy, international summits, natural disasters, and global warming, respectively. The rst two factors proxy transition risks, whereas the last two proxy physical risks. We nd that only the climate policy factor is priced in the U.S. stock market, with the evidence being more pronounced over 2012-2018. The documented positive premium is consistent with the argument that investors hedge short-term transition risks. We validate this explanation using a narrative approach to mark the content of climate news. Our results imply that investors' attention is an important driver of asset returns.
