Document Summary
Transportation is backbone of economic activity, connecting manufacturers with supply chains, consumers with products and tourism, and people with their workplaces, homes and communities across both urban and rural landscapes. Ability to perform reliably, safely efficiently is undermined by changing climate. Heavy precipitation, coastal flooding, heat, wildfires, freeze thaw cycles and changes in average precipitation and temp impact individual assets across all modes. Sea level rise making coastal roads and bridges more vulnerable and less functional. Many coastal cities in us have experienced increase in high tide flooding that reduces functionality of low elevation roadways, rail, and bridges often causing costly congestion and damage to infrastructure. Inland transportation infrastructure is highly vulnerable to intense rainfall and flooding. Loss of efficiency as well as risk of accidents. Transportation not only vulnerable to impacts of cc but also contributes significantly to the causes of cc. In 2016 transportation sector became top contributor to us ghg emissions.
