"In a warming world, the U.S. could see its cities inundated with water, its power grids threatened by intense storms, its forests devastated by wildfire and insect infestations, and its coastlines washed away by storm surges.
Climate change also threatens roads, pipelines, power lines and rail lines in ways that may not be quite as in-your-face as the stark images of homes washed away on a hurricane-eroded beach. Bridges and highways can be weakened or destroyed in floods. Power lines can be burned in wildfires and damaged in major storms. Roads and airport runways are vulnerable to extreme heat, which can soften and deteriorate asphalt.
You can add 'sun kinks,' or railways that buckle in extreme heat, causing derailments, to the list of things that are already taking a toll on U.S. transportation, a problem that figures to grow significantly as the U.S. warms."
