It is undeniable that global warming is an issue to address now, and not in the future. Science proves that temperatures have been on a steady rise, according to the Press Herald, “Don’t let a little April snow fool you. The trend is undeniable: According to the National Oceanic and Atmospheric Administration (NOAA), last year was the warmest year on record since 1880. Previously, the hottest year had been 2014, and 15 of the 16 hottest years in history have been since 2000. The 16th was 1998.” With global temperatures on the rise, there are many things that can and will change about our environment. Global warming has been associated with rises in sea levels, rises in average temperature, and even rises in the frequency and intensity of precipitation events. From a transportation engineering perspective, global warming will have effects on our current transportation infrastructure, as well as future infrastructure design. This report looks at these effects, specifically in Maine, and will discuss possible modifications engineers may have to make in anticipation of future climate change.
Maine has approximately 3,500 miles of tidal shoreline according to the NOAA, so a rather important effect we will look at is the rise in the ocean level.
Global warming also has a possibility to cause indirect effects like higher vehicle miles. Higher vehicle miles are the outcome of shorter winters because less snow falling on the roads means people drive more miles.
