Climate Risk Exposure: An Assessment of the Federal Government's Financial Risks to Climate Change [open pdf - 5MB]
From the Introduction: "The climate crisis poses a serious threat to the United States economy and human welfare, with a narrowing timeframe to invest in opportunities to avoid the most catastrophic impacts. Extreme weather events can be exacerbated by climate change, disrupting supply chains, and flooding made worse by sea level rise can destroy critical infrastructure. As a smaller subset of these impacts, climate change threatens the Nation's fiscal health. The Fourth National Climate Assessment (NCA4) notes that: 'Climate change creates new risks and exacerbates existing vulnerabilities in communities across the United States, presenting growing challenges to human health and safety, quality of life, and the rate of economic growth'. The impacts of climate change on businesses and communities are broad; escalating costs, and lost revenue as a direct or indirect result of a changing climate is significant and varied. Across the United States, estimated damages from a subset of storms, floods, wildfires, and other extreme climate-related weather events have already grown to about $120 billion a year over the past five years."
