In a November 28, 2017 report, Moody’s Investors Service warned cities and states that they faced the risk of a credit rating downgrade if they were not proactive in planning to mitigate the risks of climate change. The Moody’s report listed six indicators that it used to assess the exposure and overall susceptibility of states and municipalities to the physical effects of climate change, including share of economic activity derived from coastal areas, hurricane and weather damage as a share of the economy, and the share of homes in a flood plain. Based on these indicators, Florida, Georgia, Mississippi, and Texas were the states most at risk from climate change. Although Moody’s couldn’t point to a specific state or municipality whose rating was (or might be) downgraded as a result of a failure to plan for climate change, the Moody’s report clearly sets the stage for such downgrades in the future.
