Using a representative consumer survey in the U.S., we elicit beliefs about the economic impact of climate change. Respondents perceive a high probability of costly, rare disasters in the near future due to climate change, but not much of an impact on GDP growth. Salience of rare disasters through media coverage increases the disaster probability by up to 7 percentage points. We analyze these findings through the lens of a New Keynesian model with rare disasters. First, we illustrate how expectations of rare disasters impact economic activity. Second, we calibrate the model to capture the key aspects of the survey and quantify the expectation channel of climate change: disaster expectations lower the natural rate of interest by about 65 basis points and, assuming a conventional Taylor rule for monetary policy, inflation and the output gap by 0.3 and 0.2 percentage points, respectively. The effect is considerably stronger if monetary policy is constrained by the effective lower bound.
