4. New Hampshire (Infrastructure score: 145 out of 425 points)
According to the Environmental Protection Agency, this state has experienced a temperature rise of about three degrees over the past century. This is not good news and can have significant effects on the environment and infrastructure.
One of the most visible changes is the loss of trees and wetlands. This destroys natural habitats, and the shift from snow to rain during the winter also increases the risk of flooding.
Less snow means less tourism in the popular areas and also less meltwater for farms and forests.
In the future, researchers from the University of New Hampshire predict more frequent and intense droughts. When it rains, most probably during the winter, flooding is the number one danger for aging infrastructure, putting immense strain on roads, bridges, and utilities.
