In this sobering article, Freeman and Guzman (FG) challenge the argument that the United States could be a “climate change winner,” which asserts that, due to its temperate climate and advanced economy, climate change will benefit the United States relative to other countries or even in absolute terms. They argue that, setting aside any moral argument that the United States has an obligation to act aggressively to reduce emissions, it is independently in its self-interest to do so.
