Essential infrastructure systems such as water, energy supply, and transportation will increasingly be compromised by interrelated climate change impacts. The nation’s economy, security, and culture all depend on the resilience of urban infrastructure systems."^^ . . . "In developing key messages, the report author team engaged in multiple technical discussions via teleconference. A consensus process was used to determine the final set of key messages, which are supported by extensive evidence documented in two Technical Report Inputs to the National Climate Assessment on urban systems, infrastructure, and vulnerability: 1) Climate Change and Infrastructure, Urban Systems, and Vulnerabilities: Technical Report for the U.S. Department of Energy in Support of the National Climate Assessment , and 2) U.S. Cities and Climate Change: Urban, Infrastructure, and Vulnerability Issues . Other Technical Input reports (56) on a wide range of topics were also received and reviewed as part of the Federal Register Notice solicitation for public input. "^^ . "Recent studies have reported that population and economic growth have made urban infrastructure more fragile and deficient, with work projecting increased stresses due to climate change and increased costs of adaptation plans due to more extensive urban development. Additionally, a few publications have assessed the main drivers of vulnerability and the effects of the amalgamation of climate change stresses with other urban and infrastructure stressors."^^ . "Given the evidence base and remaining uncertainties, confidence is very high that climate change and its impacts threaten the well-being of urban residents in all regions of the U.S. Given the evidence base and remaining uncertainties, confidence is very high that essential local and regional infrastructure systems such as water, energy supply, and transportation will increasingly be compromised by interrelated climate change impacts."^^ . "Given that population trends and infrastructure assessments are well established and documented, the largest uncertainties are associated with the rate and extent of potential climate change. Since the last National Climate Assessment, recent publications have explored the driving factors of vulnerability in urban systems and the effects of the combined effect of climate change and existing urban stressors."^^ . . . . . . . . . . . . . . . . . .
